If the temperature difference reaches or exceeds the switch-on temperature difference, the pump switches on at 100% speed for 10 s. Then, the speed is reduced to the minimum pump speed value.

If the temperature difference reaches the adjusted nominal value, the pump speed increases by one step (10 %). The response of the controller can be adapted via the parameter Rise. Each time the difference increases by the adjustable rise value, the pump speed increases by 10 % until the maximum pump speed of 100% is reached. If the temperature difference decreases by the adjustable rise value, pump speed will be decreased by one step.

Note To enable speed control, the corresponding relay has to be set to AUTO, MIN, MAX or ADAP (adjustment channel MAN) and relay control to PULS, PSOL, PHEA or 0-10 V (adjustment channel REL).

Collector emergency shutdown

When the collector temperature exceeds the adjusted collector emergency temperature, the solar pump (R1 / R2) switches off in order to protect the system components against overheating (collector emergency shutdown). If the maximum collector temperature is exceeded,  is displayed (ﬂashing).

Note

If the drainback option is activated, the adjustment range of the collector emergency temperature is changed to 80 … 95 °C. Factory setting will be 95 °C.

WARNING!

Risk of injury! Risk of system damage by pressure surge!

If water is used as the heat transfer ﬂuid in pressureless systems, water will boil at 100 °C.

Î In pressureless systems with water as the heat trans-

fer ﬂuid, do not set the collector limit temperature higher than 95 °C.

Collector cooling

The collector cooling function keeps the collector temperature within the operating range by heating the store. If the store temperature reaches 95 °C the function will switch off for safety reasons. When the store temperature exceeds the adjusted maximum store temperature, the solar system switches off. If the collector temperature increases to the adjusted maximum collector temperature, the solar pump is activated until the collector temperature falls below the maximum collector temperature. The store temperature may then exceed the maximum temperature, but only up to 95°C (emergency shutdown of the store).

If the collector cooling is active,  is displayed (ﬂashing).

Tube collector function

This function is used for improving the switch-on behaviour in systems with non-ideal sensor positions (e. g. with some tube collectors).

This function operates within an adjusted time frame. It activates the collector circuit pump for an adjustable runtime between adjustable pauses in order to compensate for the delayed temperature measurement.

If the runtime is set to more than 10 s, the pump will be run at 100 % for the ﬁrst 10 s of the runtime. For the remaining runtime, the pump will be run at the adjusted minimum speed.

If the collector sensor is defective or the collector is blocked, this function is suppressed or switched off.

2-collector systems

In 2-collector systems, the tube collector function is available for each individual collector ﬁeld.

In 2-collector systems, the tube collector function will affect the inactive collector ﬁeld only. The solar pump of the active collector ﬁeld will remain switched on until the switch-off conditions are fulﬁlled.

Drainback option

In a drainback system the heat transfer ﬂuid will ﬂow into a holding tank if solar loading does not take place. The drainback option initiates the ﬁlling process if solar loading is about to start. If the drainback option is activated, the following adjustment can be made:

Note A drainback system requires additional components such as a holding tank. The drainback option should only be activated if all components required are properly installed.

Time period – switch-on condition

The parameter tDTO is used for adjusting the time period during which the switch-on condition DT O must be permanently fulﬁlled.

Filling time

The ﬁlling time can be adjusted using the parameter tFLL. During this period, the pump runs at 100 % speed.

Stabilisation

The parameter tSTB is used for adjusting the time period during which the switch- off condition will be ignored after the ﬁlling time has ended.

Note

If the drainback option is activated, the cooling function and the antifreeze function will not be available. The H-DAY menu (holiday function) will also not be available and cannot be selected by means of the microbutton .

Holiday function

The holiday function is used for operating the system when no water consumption is expected, e. g. during a holiday absence. This function cools down the system in order to reduce the thermal load.

Only if the holiday function has been activated with the parameter DAYS will the adjustments described in the following become active.

2 cooling functions are available: Collector cooling and store cooling

When the store temperature exceeds the adjusted maximum store temperature, the solar system switches off. If the collector temperature increases to the adjusted maximum collector temperature, the solar pump is activated until the collector temperature falls below the maximum collector temperature. The store temperature may then exceed the maximum temperature, but only up to 95°C (emergency shutdown of the store).

If the collector cooling is active,  is displayed (ﬂashing).

The store cooling option is activated by default and can be deactivated with the parameter OSTC. Store cooling starts when the store temperature exceeds the collector temperature by the adjustable value DTCO. It switches off if the store temperature reaches THOL or if the temperature difference falls below DTCF. The parameter THOL is used for adjusting the temperature for store cooling.

The parameter DAYS can be used for entering the number of days for a holiday absence. If the parameter is set to a value higher than 0, the function becomes active using the adjustments that have previously been made in the H-DAY menu. The days will be counted backwards at 00:00. If the value is set to 0, the function is deactivated.

Note

The parameter DAYS can be accessed via the microbutton  only (see page 29).

This function is used for monitoring the temperature difference.. The message 'T too high is shown, if solar loading has been carried out for a period of 20 min with a differential higher than 50 K. Normal operation is not aborted or inhibited, but the system should be checked for the cause of the warning.

Possible causes are:

• pump power too weak

• blocked system components

• circulation problems in the collector

• air inside the pipework

• defective valve/ defective pump

Night circulation

This function can be used for detecting thermal circulation inside the solar circuit that leads to an unwanted cooling of the store. A warning message will appear when the following condition has been detected for at least 1 min during the period between 11 p.m. and 5 a.m.:

• collector temperature exceeds 40 °C

The delay time of 1 min ensures that the message is not triggered by short-term fault conditions.

Possible causes are:

• defective non-return valves

• defective valve

• wrongly adjusted time

Flow and return interchanged

This function is used for detecting an interchange of the ﬂow and return pipe or a badly placed collector sensor. For this purpose, the collector temperature is monitored for plausibility during the switch-on phases of the solar pump. An error message will appear, if the plausibility criteria have not been met 5 times in a row.

driver; now passable?

Pump is defective - replace it.

yes

Does the DHW circulation run for

a very long time?

no yes

Use the circulation pump with timer and switch-off thermostat energy-efﬁcient circulation).

Circulation pump and blocking valve should be switched off for 1 night; less store losses?

yes no

Check whether the pumps of the after-heating circuit run at night; check whether the non-return valve is defective; problem solved?

Check the non-return valve in

warm water circulation - o.k.

yes no

The gravitation circulation in the circulation line is too strong; insert a stronger valve in the non-return valve or an electrical 2-port valve behind the circulation pump; the 2-port

valve is open when the pump is activated, otherwise it is closed; connect pump and 2-port valve electrically in parallel; activate the circulation again. Deactivate pump speed control!

Clean or replace it.

Further pumps which are connected

to the solar store must also be

checked.

11.1 Sensors and measuring instruments

Sensors

The product range includes high-precision platinum temperature sensors, ﬂatscrew sensors, outdoor temperature sensors, indoor temperature sensors, cylindrical clipon sensors, also as complete sensors with immersion sleeve.

Overvoltage protection device

In order to avoid overvoltage damage at collector sensors (e.g. caused by local lightning storms), we recommend installing the overvoltage protection SP10.

V40 ﬂowmeter

The V40 is a measuring instrument for detecting the ﬂow of water or water/glycol mixtures. After a speciﬁc volume has passed, the V40 reed switch sends an impulse to the calorimeter. The heat quantity used is calculated by the calorimeter using these impulses and the measured temperature difference with the help of pre-deﬁned parameters (glycol type, concentration, heat capacity, etc.).

11.2 VBus

accessories

SD3 Smart Display / GA3 Large Display

The Smart Display is designed for simple connection to controllers with VBus

. It is used for visualising data issued by the controller: collector temperature, store temperature and energy yield of the solar thermal system. The use of high-efﬁciency LEDs and ﬁlter glass assures a high optical brilliance and good readability even in poor visibility conditions and from a larger distance. An additional power supply is not required. One module is required per controller.

The GA3 is a completely mounted large display module for visualisation of collector- and store temperatures as well as the heat quantity yield of the solar system via one 6-digit and two 4-digit 7-segment displays. An easy connection to all controllers with VBus

is possible. The front plate is made of antireﬂective ﬁlterglass and is printed with a light-resistant UV-lacquering. The universal VBus® allows the parallel connection of 8 large displays as well as additional VBus® modules.

AM1 Alarm module

The AM1 Alarm Module is designed to signal system failures. It is to be connected to the VBus

of the controller and issues an optical signal via the red LED if a failure has occurred. The AM1 also has a relay output, which can e. g. be connected to a building management system (BMS). Thus, a collective error message can be issued in the case of a system failure.

DL3 Datalogger

Be it solar thermal, heating or DHW heat exchange controllers – with the DL3 you can easily and conveniently log system data of up to 6 controllers. Get a comprehensive overview of all controllers connected with the large full graphic display. Transfer data with an SD memory card, or use the LAN interface to view and process data on your PC.

DL2 Datalogger

This additional module enables the acquisition and storage of large amounts of data (such as measuring and balance values of the solar system) over a long period of time. The DL2 can be conﬁgured and read-out with a standard Internet browser via its integrated web interface. For transmission of the data stored in the internal memory of the DL2 to a PC, an SD card can be used. The DL2 is appropriate for all controllers with VBus

. It can be connected directly to a PC or router for remote access and thus enables comfortable system monitoring for yield monitoring or for diagnostics of faults.

11.3 Interface adapters

VBus

/ USB & VBus® / LAN interface adapters

The VBus

/ USB interface adapter is the interface between the controller and a personal computer. With its standard mini-USB port it enables a fast transmission of system data for processing, visualising and archiving data via the VBus®. A full version of the ServiceCenter software is included.

The VBus

/ LAN interface adapter is designed for the direct connection of the controller to a PC or router. It enables easy access to the controller via the local network of the owner. Thus, controller access and data charting can be effected from every workstation of the network. The VBus® / LAN interface adapter is suitable for all controllers equipped with a VBus®. A full version of the ServiceCenter software is included.
