Your solar storage heater controller

2.1

What your solar storage heater controller does

When correctly programmed and used in conjunction with an appropriate hydraulic circuit, the controller helps make the most of incident solar energy. This can make a conventional boiler unnecessary.

2.2

User adjustments

The front-panel controls allow you, as user, to do the following: • "Select operating mode (without access code)" (page 14) • "Read temperatures and values, change regular display (access code 1)" (page 17) • "Test outputs or include them in the regular display (access code 1)" (page 19) All other adjustments may be performed only by qualified personnel. Improper adjustment can lead to malfunctioning of the solar heating system, or a reduction in operating life.

2.3

Parameters/access code protection

Parameters are values that may be modified or included in the regular display, or functions that may be activated/deactivated. The range of possible adjustments is divided into 3 authorization categories: Category Authorization required to modify

Display

The regular display is recognisable by the four items with a dotted line running across the middle. The first three lines show temperatures, values, or output switching states. the fourth line shows the current operating mode. In manual mode, blinking arrows at the left and right, next to manual, warn of incorrect operation.


In the event of a fault, auto alternates with Err. There is a list of display abbreviations and their meanings in the section "19 Explanation of terms and abbreviations", on page 49. If you have changed to another display, the controller always reverts to the regular display after a two-minute timeout interval. A menu contains just text, without the dotted line.


A submenu includes a dotted line across the middle of the display.

Description of functions

After you have chosen the hydraulic variant correct for your heating system from the list in chapter "15.3 Hydraulic variants", page 37, you will find a description of possible functions given in the following.

10.1

Collector minimum temperature

In order for solar charging to be enabled, the collector temperature TKO must be above this set value. The "minimum collect. temp." limiting value is set to a switching hysteresis of -5K. (Example: collector min. 20 °C, enabled at 20 °C; disabled at 15 °C.)


10.2

Solar charging without return flow sensor for DHW tank, storage tank or swimming pool

Enabling of the solar pump PS takes place when the difference in temperature between the collector sensor TKO and the consumer sensor (TBU, TPU, TSB) is larger as the defined set value "differ on". The solar pump is switched off if the difference in temperature between the collector sensor and the consumer sensor (TBU, TPU, TSB) is smaller than the defined set value "differ off" or if a maximum or set temperature by the consuming units or collector is exceeded. Using speed control (revs) it is attempted to maintain a minimum temperature difference at the collector sensor (TKO, TKO2). The value Xs for the speed control is calculated using following formula: Xs TKO-DHW tank

= TBU + ½ x (differ on + differ off)

Xs TKO-storage tank

= TPU + ½ x (differ. 2 on + differ. 2 off)

Xs TKO-swimming pool

= TSB + ½ x (differ. 3 on + differ. 3 off)

The solar pump PS is started with the set value PS maximum revolut.

10.3

Solar charging with return flow sensor for DHW tank, storage tank or swimming pool

The solar pump is switched on if the difference in temperature between the collector sensor and the consumer unit sensor (TBU, TPU, TSB) is larger than the determined set value "differ on".

Operating instructions Solar Energy Controller PS 5511 S-3.2 The solar pump PS is switched off when the difference in temperature between collector sensor and consumer unit sensor (TBU, TPU, TSB) is smaller than the defined set value "differ off" or if a maximum or set temperature at the consumer units or collector is exceeded. Using speed control, it is attempted to maintain a minimum temperature difference at the collector sensor (TKO, TKO2). The value Xs for the speed control is calculated using following formula: Xs TKO-DHW tank

Xs TKO-swimming pool

= TKR + ½ x (differ. 3 on + differ. 3 off)

10.4

Legionella protection function

According to the DIN DVGW worksheet W 551 for DHW tanks. This function is fully integrated and switches the output 5 on for maximum 2 hours every 24 hours at around 10.00 p.m. If the TBU has not reached the pre-set legionella temperature "legion. temp." within the 24 hours the pump PSZ is switched on at 10.00 p.m. If the "external DHW tank" option is activated and, therefore, energy management of a compatible heating controller is available, the heat generator is switched on in addition to pump PSZ. If the set "legion. temp." is reached before the end of the 2 hour time period, the function is satisfied and the circulation pump PSZ is switched off again. If this function is present, the time can be changed and controlled under "adjust. paramet. settings" without use of an access code. If the pre-determined "legion. temp." value is set to 0, the function is de-activated.

10.5

Bypass function

The following conditions must be fulfilled for the bypass valve UBY to switch over to the consumer circuit DHW tank or storage tank (on). The bypass temperature TBY is higher than the temperature at the consumer sensor TBU/TPU + differ off + 2K and the solar pump PS is enabled. The bypass valve UBY switches back to the collector circuit if the bypass temperature TBY is lower than the temperature at the consumer sensor TBU/TPU + differ off or when the solar pump PS is disabled.

The solar pump PS is started with the set value PS maximum revolut.


10.6

Consumer cascade (DHW tank, storage tank, swimming pool)


Based on the solar input, the controller distinguish whether the consumers have to be charged to temperature or to energy. The priorities for charging the consumers units can be defined with the selection "priority solar charging". 10.6.1 Charging to energy This charging mode is used if only a small amount of solar energy is available and becomes operational when the following conditions are given. The average speed (revs) PSm of the solar pump PS increases but still remains less than 80%, or the average speed PSm of the solar pump PS sinks below 70%. In the case the DHW tank/storage tank with the lowest temperature, and not reached set value, will be charged first. First, the DHW tank/storage tank units are brought to the same temperature, then the DHW tank is heated by 5K. If the temperature at the sensor TBU is increased by +5K the storage tank TPU is enabled. This continues until DHW tank/storage tank has reached its set value. The swimming pool TSB is then charged. If the set value is reached, the charge is passed to the DHW tank until the pre-determined DHW tank maximum value is exceeded. If more energy is still available the storage tank is then charged up to the set maximum value. 10.6.2 Charging to temperature This charging mode is used when large amounts of solar energy are available. It becomes operational when the following conditions are given. The average speed PSm of the solar pump PS increases and is greater than 80%, or the average speed PSm of the solar pump PS sinks but remains above 70%. Depending on the priorities selected, the single consumer units are charged one after another until they reach their set values. If more energy is still available, DHW tank and storage tank are then charged up to their set maximum values. 10.6.3 Order of charging of the consumer units A choice of four different charging sequences is available. If one of the given consumer units is not available the next will be automatically chosen: •

26

Priority solar charging = 0 (automatic charging to energy "10.6.1" or charging to temperature "10.6.2") DHW tank (TBU) - storage tank (TPU) - swimming pool (TSB) When the set temperatures are reached charging continues in the following sequence until the maximum temperatures are reached: DHW tank (TBU) - storage tank (TPU).

Dok. Nr. 107694 04/2002

•

Priority solar charging = 1 (pre-determined charging to temperature "10.6.2") DHW stank (TBU) - swimming pool (TSB) - storage tank (TPU) When the set temperatures are reached charging continues in the following sequence until the maximum temperatures are reached: DHW tank (TBU) - storage tank (TPU)

•

Priority solar charging = 2 (pre-determined charging to temperature "10.6.2") Storage tank (TPU) - DHW tank (TBU) - swimming pool (TSB) When the set temperatures are reached charging continues in the following sequence until the maximum temperatures are reached: Storage tank (TPU) - DHW tank (TBU)

•

Priority solar charging = 3 (pre-determined charging to temperature "10.6.2") Swimming pool (TSB) - DHW tank (TBU) - storage tank (TPU) When the set temperatures are reached charging continues in the following sequence until the maximum temperatures are reached: DHW tank (TBU) - storage tank (TPU)

10.7

Frost protection function

The controller has a frost protection function. If the temperature at the collector sensor TKO falls below the frost limit selected, the solar pump PS is switched on at its lowest speed. If the temperature at TKO increases to 3 K above the set frost limit the pump is switched off. Note: This setting cannot be changed via the operating structure. The factory setting is -50 °C.

10.8

Auxiliary boiler function

The solar controller has four different auxiliary boiler functions. 10.8.1 Auxiliary boiler minimum temperature For the auxiliary boiler to be released, the temperature in this boiler TFK must be higher than the set value. The minimum temperature limiting value minimum aux.b. temp. has a switching hysteresis of -5 K. (Example: auxiliary boiler min. temp. 30 °C; enabled at 30 °C, disabled at 25 °C).

Dok. Nr. 107694 04/2002

27



Operating instructions Solar Energy Controller PS 5511 S-3.2 10.8.2 Auxiliary boiler function without thermal return flow increase The setting aux. b. temp. increase must be set to 0. The boiler circulation pump PFK is enabled when the difference in temperature between the sensor of the auxiliary boiler TFK and the storage tank sensor TPU is larger than the pre-defined set value "aux.b. differ on." The auxiliary boiler circulation pump PFK is switched off when the difference in temperature between the TFK sensor auxiliary boiler and the storage tank sensor TPU is smaller than the pre-set set value "aux.b. differ off". A minimal charging temperature difference at auxiliary boiler sensor TFK is maintained by speed regulation. The value Xs for the speed control is calculated from the following formula:


Xs TBO aux. boiler = storage tank temp. set value + ½ x (aux. boiler diff. on + aux. boiler diff. off)

10.8.3 Auxiliary boiler function with thermal return flow increase If a thermal return flow increase is used, the auxiliary boiler circulation pump PKF can be enabled due to the increase in temperature at the auxiliary boiler sensor TFK. A minimal charging temperature difference at sensor TFK is maintained by speed regulation. The value Xs for the speed control is calculated from following formula: Xs TFK aux. boiler = storage tank temp. set value + ½ x (aux. boiler diff. on + aux. boiler diff. off)

The aux. boiler circulation pump PFK may also be enabled due to the increase in temperature at the auxiliary boiler sensor TFK. 10.8.4

Release of the aux. boiler circulation pump PFK due to the increase in temperature at the sensor TFK If the increase in temperature in the auxiliary boiler is sufficient, the aux. boiler pump PFK is switched on even though the boiler temperature is less than the "minimum aux. b. temp." and the difference in temperature between TPU and TFK is not sufficient. Over a continual period of 10 minutes, an average value is taken from the actual auxiliary boiler temperature TFK. If the increase in aux. boiler temperature at sensor TFK is higher than calculated average value by the value "aux.b. temp. increase x 5 K", PFK is switched on for a period of 10 minutes at minimum speed. If, after 10 minutes, the criteria, aux. boiler temp. min. and difference in temperature between auxiliary boiler sensor TFK and storage tank sensor TPU are fulfilled, the aux. boiler circulation pump PFK remains switched on.

Operating instructions Solar Energy Controller PS 5511 S-3.2 10.8.5 Auxiliary boiler function with 3-point mixing valve motordrive for the return flow temperature control function The boiler circulation pump PFK is enabled when the difference in temperature between the auxiliary boiler sensor TFK and the return flow sensor TFR is greater than the pre-set set value "aux. boiler diff. on". The auxiliary boiler circulation pump PFK is switched off when the difference in temperature between the auxiliary boiler sensor TFK and the return flow sensor TFR is less than the pre-set set value "aux. boiler diff. off". Using speed control, it is attempted to reach and maintain a minimal difference tank temperature at auxiliary boiler sensor TFK. The value Xs for the speed control is calculated from following formula:

The aux. boiler circulation pump PFK may also be enabled due to the increase in temperature at the auxiliary boiler sensor TFK. See "10.8.4" for details. In both cases, with an activated pump PFK, the 3-point mixing valve MR is used to try and reach and maintain the minimum temperature, minimum aux.b. temp. at the sensor TFR. The mixing valve is set with a p-band of ± 5 K.

10.9

Cooling down function

If the temperature at the top DHW tank sensor TBO or top storage tank sensor TPO rises to 3K above the set DHW tank or storage tank maximum value, the pump PRK is switched on. The pump PRK is switched off when the temperature at sensor TBO or TPO falls below the set DHW tank or storage tank maximum value. If the sensors TBO or TPO are not available, the temperatures at sensor TBU or TPU are used to control this cooling-down function.

Options

Depending on the hydraulic variant chosen (refer to "15.3 Hydraulic variants", page 37), only the options available for selection are displayed and can be selected.

11.1

External DHW tank


If the option "yes" is chosen the solar controller may be operated over an eBUS with a compatible heating controller and economical use of energy for after-heating of the DHW tank can be ensured. The DHW tank sensor must be connected to the heating controller. The "DHW tank set value" and the "minimum DHW tank temperature" are adjusted on the heating controller. The two settings "DHW tank temp. setting" and "maximum DHW tank temp." in the solar controller do not have any function and are not displayed. The bottom DHW tank sensor TBU and the top DHW tank sensor TBO are also not displayed. The DHW tank set value will be set to the adjustable "minimal DHW tank temperature" for after-heating when a good solar yield (average revolutions of the solar pump PSm above 50 %) is available. This reduction is removed when the average revs PSm of the solar pump are below 50 %. The after-heating is set to minimum DHW tank temperature for 18 hours if the "DHW tank set temperature" is reached with solar energy and the average revolutions of the solar pump PSm drop below 80 % or the DHW tank temperature falls below the set value. This reduction is de-activated by a reset or power failure to the controller. Note: If there is selected a hydraulic variant with auxiliary boiler function and the auxiliary boiler pump PFK is switched on, the DHW tank set value is switched to DHW tank minimal temperature.

11.2

External storage tank

If the option "yes" is chosen the solar controller may be operated over an eBUS with a compatible heating controller and economical use of energy for after-heating of the DHW tank can be ensured. The storage tank sensor must be connected to the heating controller. The size in reduction of the set value is adjusted on the heating controller. The two settings "tank temp. settings" and "maximum tank temp." in the solar controller do not have any function and are not displayed. The bottom storage tank sensors TPU and the top storage tank TPO are also not displayed. 30

Dok. Nr. 107694 04/2002

Operating instructions Solar Energy Controller PS 5511 S-3.2 When a good solar yield (average revolutions of the solar pump above 50 %) is available, the storage tank set value (dependant on demand) for the after heating is reduced by an adjustable amount (e.g. 15 K). The reduction is de-activated if the average revolutions PSm of the solar pump PS drop below 50 %. The storage tank set value is continually calculated by the heating controller. The degree of reduction of the set value is adjusted on the heating controller Note: If a variant with auxiliary boiler function is selected and the aux. boiler pump PFK is activated, the reduction in storage tank set value becomes activated.

11.3

Overheating protection

• • • • • •

collector switch-on temperature collector switch-off temperature collector protection temperature DHW tank protection temperature storage tank protection temperature swimming pool protection temperature

110 °C 100 °C 130 °C pump always disabled 95 °C pump always disabled 95 °C pump always disabled no switch-off

If the TBO or TPO sensors are connected, this takes the function of overheating protection, otherwise the TBU or TPU sensors perform this function. If the TKO rises above 110 °C, the solar pump is switched on with lowest power (even when DHW or storage tank maximum has been reached) and, using speed control, attempts to maintain the collector temperature at 110 °C. If the TKO increases to above 130 °C the pump is disabled. The pump is also disabled if the TKO sinks below 100 °C (if DHW or storage tank maximum has been reached). At the DHW storage tank protection threshold temperature of 95 °C the pump PS is always disabled and then re-enabled when the DHW storage tank temperature sinks below 93 °C. Priority overheating protection: If overheating of the collector occurs, the heat is passed to the available heat consumption units DHW tank, storage tank or swimmingpool. As a rule, a fixed order for allocation is defined in the controller. Swimming pool-storage tank-DHW tank. The first available consumption unit is compelled to accept the heat.

Dok. Nr. 107694 04/2002

31


An overheating protection with the following set values is stipulated:


11.4

Flowmeter pulse counter

If this selector is activated a flow meter with pulse output VIG and return flow sensor TKR must be connected to the controller. The performance calculation of the solar output is now made on the basis of the difference in temperature between the collector sensor TKO and the return sensor TKR, the flow volume recorded VIG and the selected heating capacity of the heat transfer medium.

11.5

Collector flow sensor

If this option is activated, the difference in temperature between collector flow and collector return flow is used to determine the performance output. The collector flow sensor disables the solar pump at a temperature above of 105 °C.


11.6

Radiation sensor (heat sensor)

Activation of this function allows the solar unit to be enabled for a period of 2 minutes following a defined increase in temperature (1 K/min.) or the minimum radiation temperature (30 °C) at the radiation sensor TST. If circulation at the collector sensor TKO still gives the enabling criteria, the solar pump PS remains operational. If the enabling criteria are not given, the solar pump PS is disabled again. If the increase in temperature at the radiation sensor TST remains given or the temperature is higher than the minimum radiation temperature, the solar pump PS is enabled again after 5 minutes. The setting "radiation min./temp. increase/ switch-on and waiting time" cannot be adjusted via the operating system.

Power calculation without a flowmeter and solar return sensor

13.1

Calculating solar power

For the controller to calculate and display power without the help of a flowmeter VIG and solar return sensor TKR, the system's solar power capability must be derived from manufacturer's specifications as shown:


α Installed collector power (kW)

Solar power (kW)

orientation factor

inclination factor

thermal coefficient of heat transfer medium

Set the resulting value in the solar collect. power submenu (see "5" (page 45)).

13.2

Setting the system flow rate

Flow rate in litres per hour is calculated using the following formula: Solar power (W) Flow rate V (l/h) =

∆T x thermal coefficient of heat transfer medium

Solar power (W)

see "13.1 Calculating solar power", page 34

∆T

= 10K (aligned at max. pump revolutions)

Thermal coefficient of the heat transfer mediumsee manufacturer's specifications The calculated flow rate V (l/h) must be set by adjusting a throttle valve (tachosetter or similar) in the system.

34

Dok. Nr. 107694 04/2002

Remote display of temperatures and values

Using the solar remote display FD 5411 it is possible to display the temperatures and values of the chosen hydraulic variants. The communication/supply to the remote display is carried out via eBUS.

15

Installation

15.1

Installation and set-up instructions

Before putting the controller into operation, check all electrical connections to the various system components. It may be necessary to electrically suppress strongly inductive loads in the vicinity of the controller (contactors, solenoid-operated valves, etc.). This can be done by connecting RC circuit directly to the coil terminals of the disturbing components. Recommended RC circuit: 0.047µF, 100Ω, rated at 250 VAC (e.g. Bosch, RIFA, etc.).

Dok. Nr. 107694 04/2002

35


Electrical installation and fuse protection must comply with local regulations. The solar controller must be powered continuously, to ensure operation at all times. Upstream switchgear should therefore be limited to emergency or main switches that are permanently "on".


15.2

Connector layout

Observe the connector layout in the diagram below, and the connector pin-outs in the section "Hydraulic variants" (page 37) when wiring up the controller. Sensor cables leading to the controller must be routed separately from power cables. The electrical supply must be switched off (controller and contacts isolated): • before opening the connector area • while wiring up the controller


Never touch the controller connectors!
