PE and load terminals

Connecting the device to the mains supply must always be the last step of the installation!

The power supply to the controller must be carried out via an external power switch (last step!). The supply voltage must be 100 … 240 V~ (50 … 60 Hz). Flexible cables must be attached to the housing with the enclosed strain relief and the corresponding screws.

The controller is equipped with a semiconductor relay, to which a load such as a pump, a valve etc. can be connected:

Relay 1

18 = conductor R1 17 = neutral conductor N 13 = protective conductor

The mains supply is to be carried out at the terminals: 19 = neutral conductor N

20 = conductor L 12 = protective conductor ⏚ The temperature sensors (S1 up to S4) are to be connected to the following terminals with either polarity: 1 / 2 = Sensor 1 (e.g. Sensor collector) 3 / 4 = Sensor 2 (e.g. Sensor store) 5 / 6 = Sensor 3 (e.g. Sensor store top) 7 / 8 = Sensor 4 (e.g. Sensor return) All Pt1000 temperature sensors are equipped with a platinum measuring element in their tip. The electrical resistance of the measuring element changes in relation to the temperature (see table in chap. 5). The difference between FKP and FRP type sensors only lies in the cable insulation material. The insulation material of FKP type sensor cables resists a higher temperature, so that FKP type sensors should be used as collector sensors. FRP type sensors are best used as reference sensors in stores or pipes.

The controller is equipped with 1 input for a digital VFD Grundfos Direct Sensor™ for measuring the ﬂow rate and the temperature. Connection is made at the VFD terminal (bottom left).

1.4 PWM output

The speed of a HE pump is adjusted through a PWM signal. In addition to connection to the relay, the pump must be connected to the PWM output of the controller.

Power is supplied to the HE pump by switching the relay on or off. The two left-hand pins of the connection marked “PWM” are the control output

for a pump with PWM control input. The two right-hand pins are inactive.

Drainback system layout

System layout 1

The controller calculates the temperature difference between collector sensor S1 and store sensor S2. If the difference is larger than or identical to the adjusted switch-on temperature difference (DT O), the solar pump will be operated by relay 1, and the store will be loaded until the switch-off temperature difference (DT F) or the maximum store temperature (S MX) is reached.

Sensors S3 and S4 can optionally be connected for measurement purposes. S3 can optionally be used as reference sensor for the store emergency shutdown option (OSEM).

If heat quantity measurement (OHQM) is activated, S4 and VFD are to be connected as ﬂow and return sensors respectively.

4.2 Adjustment channels

∆T control

DT O

Switch-on temperature diff. Adjustment range: 1.0 … 20.0 K [2.0 … 40.0 °Ra] Factory setting: 6.0 K [12.0 °Ra]

The controller works as a standard differential controller. If the switch-on difference is reached, the pump is activated. When the temperature difference falls below the adjusted switch-off temperature difference, the respective relay switches off.

Note:

The switch-on temperature difference must be at least 0.5 K [1 °Ra] higher than the switch-off temperature difference.

DT F

Switch-off temperature diff. Adjustment range: 0.5 … 19.5 K [1.0 … 39.0°Ra] Factory setting: 4.0 K [8.0°Ra]

Note:

When the drainback option ODB is activated, the temperature differences DT O, DT F and DT S are set to a ﬁxed adjustment:

DT O = 10 K [20 °Ra] DT F = 4 K [8 °Ra] DT S = 15 K [30 °Ra] Previous adjustments made in these channels will be overridden and may

have to be entered again if ODB is deactivated later on.

Pump speed control

DT S

Nominal temperature difference Adjustment range: 1.5 … 30.0 K [3.0 … 60.0 °Ra] Factory setting: 10.0 K [20.0 °Ra]

RIS

Rise Adjustment range: 1 … 20 K [2 … 40 °Ra] Factory setting: 2 K [4 °Ra]

Note:

For pump speed control, the operation mode of the relay must be set to Auto (adjustment channel MAN)

When the switch-on temperature difference is reached, the pump is activated at full speed for 10 seconds. Then, the speed is reduced to the minimum pump speed value (factory setting = 30 %).

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

Note:

The nominal temperature difference must be at least 0.5 K [1 °Ra] higher than the switch-on tempe rature difference.

PUM

Pump control type Selection: OnOF, PULS, PSOL, PHEA Factory setting: PSOL

With this parameter, the pump control type can be adjusted. The following types can be selected: Adjustment for standard pump without speed control

• OnOF (pump on / pump off) Adjustment for standard pump with speed control

• PULS (pulse packet control via semiconductor relay) Adjustment for high efﬁciency pump (HE pump)

• PSOL (PWM proﬁle for a high-efﬁciency solar pump)

• PHEA (PWM proﬁle for a high-efﬁciency heating pump)

In order to reduce the number of switching processes for high-efﬁciency pumps, the controller is equipped with a relay overrun function that automatically comes into effect when the speed control signal is not issued by the relay itself (PUM = PSOL or PHEA). The corresponding relay will then remain switched on for an hour after the switch-off conditions are fulﬁlled.

WARNING!

Electric shock!

During the overrun time, the relay symbol disappears from the display and the pump is inactive, but the relay is still energised!

Î Switch off power supply and disconnect the device

from power supply before working on the device or the cables connected!

Minimum pump speed

nMN

Minimum pump speed Adjustment range: (10) 30 … 100 % Factory setting: 30 % A relative minimum pump speed can be allocated to the output R1 via the adjustment channel nMN.

Note:

When loads which are not speed-controlled (e.g. valves) are used, the value must be set to 100 % in order to deactivate pump speed control.

nMX

Maximum pump speed Adjustment range: (10) 30 … 100 % Factory setting: 100 %

A relative maximum pump speed can be allocated to the output R1 via the adjustment channel nMX.

Note:

When loads which are not speed-controlled (e. g. valves) are used, the value of the relay must be set to 100% or the pump control type must be set to OnOF in order to deactivate pump speed control.

Maximum store temperature

S MX

Maximum store temp. Adjustment range: 4 … 95 °C [40 … 200 °F] Arr 3: 4 … 90 °C [40 … 190 °F] Factory setting: 60 °C [140 °F]

Once the adjusted maximum temperature is exceeded, the solar pump is switched off and further loading of the store is prevented to reduce scald risk or system damage. A ﬁxed hysteresis of 2 K [4 °Ra] is set for the maximum store temperature.

When the temperature at the corresponding sensor exceeds the adjusted maximum store temperature, the ☼ symbol is shown on the display.

Note: If the collector cooling or the system cooling function is activated, the adjusted store temperature may be overridden. In order to prevent system damage, the controller is also equipped with an integrated store emergency shutdown if the store reaches 95 °C [200 °F].

Store emergency shutdown option

OSEM

Store emergency shutdown option Adjustment range: OFF / ON Factory setting: OFF

This option is used for activating the integrated store emergency shutdown for an upper store sensor. If the temperature at the reference sensor exceeds 95 °C

[200 °F], the store will be blocked and loading will be stopped until the tempera-

ture falls below 90 °C [190 °F]

Note:

Sensor S3 ist used as the reference sensor.

Collector temperature limitation Emergency shutdown of the collector

Collector temperature limitation Adjustment range: 80 … 200 °C [170 … 390 °F] Factory setting: 130 °C [270 °F]

If the adjusted collector emergency shutdown temperature (EM) is exceeded, the controller switches off the solar pump (R1) in order to protect the system against overheating (collector emergency shutdown). A hysteresis of 10 K [20 °Ra] is set for the collector temperature limitation. While the collector is in emergency shutdown, ⚠ (ﬂashing) is shown on the display.

Note:

If the drainback option ODB is activated, the adjustment range of EM is changed to 80 … 120 °C [170 … 250 °F]. The factory setting in that case is 95 °C [200 °F].

WARNING!

Danger of injury and system damage through pressure surges!

If water is used as a heat transfer medium in a pressure-less system, the water will start boiling at 100 °C [212 °F].

Î If a pressure-less drainback system is used with water

as a heat transfer medium, do not adjust the collector temperature limitation EM to more than 95 °C [200 °F]!

Cooling functions

In the following the three cooling functions – collector cooling, system cooling and store cooling – are described in detail. The following note is valid for all three cooling functions:

Note:

The cooling functions will not become active as long as solar loading is possible.

Collector cooling function

OCC

Option collector cooling Adjustment range: OFF / ON Factory setting: OFF

CMX

Maximum collector temp. Adjustment range: 70 … 160 °C [150 … 320 °F] Factory setting: 110 °C [230 °F]

When the collector cooling function is activated, the controller aims to keep the collector at an operational temperature.

When the adjusted maximum store temperature is reached, solar loading stops. If the collector temperature increases to the adjusted maximum collector temperature, the solar pump is activated until the collector temperature falls at least 5 K [10 °Ra] below the maximum collector temperature. The store temperature may increase (subordinate active maximum store temperature), but only up to 95 °C [200 °F] (emergency shutdown of the store).

If the collector cooling function is active, ⓵ and ☼ (ﬂashing) is shown on the display.

Note:

This function will only be available if the system cooling function (OSYC) is deactivated.

Note:

In system layout 3, the parameter CMX is available without the OCC function. In system layout 3, CMX is used to set the activation temperature for the heat dump function. No other switch-on condition is needed in that case.

System cooling function

OSYC

Option system cooling Adjustment range: OFF / ON Factory setting: OFF

DTCO

Switch-on temperature diff. Adjustment range: 1.0 … 30.0 K [2.0 … 60.0 °Ra] Factory setting: 20.0 K [40.0°Ra]

When the system cooling function is activated, the controller aims to keep the solar system operational for a longer time. The function overrides the maximum store temperature to provide thermal relief of the collector ﬁeld and the heat transfer ﬂuid on hot days.

If the store temperature is higher than the maximum store temperature (S MX) and the switch-on temperature difference DTCO is reached, the solar system remains activated. Solar loading is continued until either the store temperature reaches 95 °C [200 °F] (emergency shutdown of the store), the temperature difference falls below the adjusted value DTCF or the collector emergency shutdown temperature EM is reached.

If the system cooling function is active, ⓵ and ☼ (ﬂashing) is shown on the display.

DTCF

Switch-off temperature diff. Adjustment range: 0.5 … 29.5 K [1.0 … 59.0 °Ra] Factory setting: 15.0 K [30.0 °Ra]

Note:

This function will only be available if the collector cooling function (OCC) is deactivated.

Store cooling function

OSTC

Store cooling option Adjustment range: OFF / ON Factory setting: OFF

OHOL

Holiday cooling option Adjustment range: OFF / ON Factory setting: OFF

THOL

Holiday cooling temperature Adjustment range: 20 … 80 °C [70 … 175 °F] Factory setting: 40 °C [110 °F]

When the store cooling function is activated, the controller aims to cool down the store during the night in order to prepare it for solar loading on the following day.

If the adjusted maximum store temperature (S MX) is exceeded and the collector temperature falls below the store temperature, the system will be reactivated in order to cool down the store. Cooling will continue until the store temperature has fallen below the adjusted maximum store temperature (S MX) again. A ﬁxed hysteresis of 2 K [4 °Ra] is set for this function.

Reference threshold temperature differences for the store cooling function are DT O and DT F.

If no DHW consumption is expected for a longer period of time, the additional holiday cooling option OHOL can be activated in order to extend the store cooling function. The adjustable temperature THOL then replaces the maximum store temperature (S MX) as a switch-off temperature for the store cooling function.

When the holiday cooling function is activated, ☼ and ⚠ (ﬂashing) are shown on the display.

While the holiday cooling function is active, ⓵, ☼ and ⚠ (ﬂashing) are shown on the display.

Collector minimum limitation option

OCN

Collector minimum limitation Adjustment range: OFF / ON Factory setting: OFF

CMN

Collector minimum temp. Adjustment range: 10.0 … 90.0 °C [50.0 … 190.0 °F] Factory setting: 10.0 °C [50.0 °F]

If the collector minimum limitation option is activated, the pump (R1) is only switched on if the adjustable collector minimum temperature is exceeded. The minimum temperature prevents the pump from being switched on too often at low collector temperatures. A ﬁxed hysteresis of 5 K [10 °Ra] is set for this function

If the collector minimum limitation is active, ❄ (ﬂashing) is shown on the display.

Note:

If OSTC or OCF is active, the collector minimum function will be overridden. In that case, the collector temperature may fall below CMN.

OCF

Antifreeze function Adjustment range: OFF / ON Factory setting: OFF

CFR

Antifreeze temperature Adjustment range: -40.0 … +10.0 °C [-40.0 … +50.0 °F] Factory setting: 4.0 °C [40.0 °F]

The antifreeze function activates the loading circuit between the collector and the store when the temperature falls below the adjusted antifreeze temperature. This will protect the ﬂuid against freezing or coagulating. If the adjusted antifreeze temperature is exceeded by 1 K [2 °Ra], the loading circuit will be deactivated.

When the antifreeze function is activated, ❄ is shown on the display. If the anti-

freeze function is active, ⓵ and ❄ (ﬂashing) are shown on the display.

Note:

Since this function uses the limited heat quantity of the store, the antifreeze function should be used in regions with few days of temperatures around the freezing point. The antifreeze function will be suppressed if the store temperature falls below 5 °C [40 °F] in order to protect the store from frost damage.

Grundfos Direct Sensor™ registration

GFD:

Grundfos Direct Sensor™ registration Selection: OFF, 12, 40, 40F Factory setting: OFF

Registration of a digital ﬂow rate sensor which can be used for heat quantity measurement.

OFF : no Grundfos Direct Sensor™ 12 : VFD 1 - 12 (water / glycol mixture) 40 : VFD 2 - 40

40F : VFD 2 - 40 Fast (water only)

Heat quantity measurement

OHQM:

Heat quantity measurement Adjustment range: OFF / ON Factory setting: OFF

If OHQM is activated, the heat quantity gained can be calculated and displayed. Heat quantity measurement can be run in 2 different ways (see below): with a ﬁxed

ﬂow rate value or with a VFD Grundfos Direct Sensor™.

Î Activate the heat quantity measurement option in the OHQM channel Î Select the ﬂow rate detection type in the SEN channel

Heat quantity measurement with a ﬁxed ﬂow rate value

Heat quantity measurement is possible if a ﬂowmeter is used. To enable heat quantity measurement, proceed as follows:

Î Read the ﬂow rate (l/min) from the ﬂowmeter at maximum pump speed and

adjust it in the FMAX channel

Î Adjust the heat transfer ﬂuid and the concentration of the antifreeze in the

channels MEDT and MED%.

FMAX:

Flow rate in l/min Adjustment range: 0.5 … 100.0 Factory setting: 6.0

Note:

The FMAX channel will be available only if the SEN channel has been set to OFF.

Heat quantity measurement with a VFD Grundfos Direct Sensor™

Heat quantity measurement with a VFD Grundfos Direct Sensor™ is possible in all system layouts.

In order to use a VFD Grundfos Direct Sensor™ for heat quantity measurement, proceed as follows:

Î Register the VFD Grundfos Direct Sensor™ in the GFD channel. Î Adjust the position of the VFD Grundfos Direct Sensor™ in the SEN channel. Î Adjust the type and ratio of the heat transfer ﬂuid in the channels MEDT and

MED%.

LS / G-LS

MED%:

Antifreeze ratio in Vol-% (MED% is hidden when MEDT 0 or 3 is used.) Adjustment range: 20 … 70 % Factory setting: 45 %

Drainback option

Note:

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

A drainback system permits the heat transfer ﬂuid to drain back into the holding tank when solar energy is not collected. The drainback option will initiate the ﬁlling of the system when solar loading begins.

If the drainback option ODB is activated, the pump will operate at 100 % speed for the adjusted ﬁlling time tFLL in order to ﬁll the system with ﬂuid from the holding tank. After tFLL, pump speed will go down to the adjusted minimum pump speed nMn. The switch-off conditions will then be ignored for the stabilisation time tSTB in order to avoid the system from shutting down prematurely.

If the function is activated, the menu items described in the following (tDTO, tFLL and tSTB) have to be adjusted:

ODB:

Drainback option Adjustment range: OFF / ON Factory setting: OFF

Note: When the drainback option ODB is activated, the cooling functions OCC, OSYC and OSTC as well as the antifreeze function OCF are

not available. If OCC, OSYC, OSTC or OCF have already been activated before, they will be deactivated again as soon as ODB is activated. They will remain deactivated, even if ODB is deactivated later on.

Note:

When the drainback option ODB is activated, the temperature differences DT O, DT F and DT S as well as the minimum speed values nMN are set to a ﬁxed adjustment. Additionally, the adjustment range and the factory setting of the collector emergency shutdown temperature EM changes (see the corresponding channel descriptions for further information). Previous adjustments made in these channels will be overridden and have to be entered again if ODB is deactivated later on.

Time period - switch-on conditions

tDTO:

Time period - switch-on conditions Adjustment range: 1 … 100 s Factory setting: 60 s

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

Filling time

tFLL:

Filling time Adjustment range: 1.0 … 30.0 min Factory setting: 5.0 min

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

Stabilisation

tSTB:

Stabilisation Adjustment range: 1.0 … 15.0 min Factory setting: 2.0 min

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