Electrical connection
WARNING!
ESD damage!
Electrostatic discharge can lead to damage to electronic components!
ÎÎTake care to discharge properly before touching
the inside of the device.To do so, touch a grounded
surface such as a radiator or tap!
Note:
The minimum pump speed must be set to 100 % when auxiliary relays or
valves are connected.
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

Note:
The mains supply is to be carried out at the terminals:
The mains connection must be carried out with the common ground 19 = neutral conductor N

Terminal allocation
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.

• 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!
ÎÎ Switch off power supply and disconnect the device
from power supply before working on the device or
the cables connected!

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.
20
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.

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.
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.

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

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
