4. - Settings
The system parameters are set in menu “4.
Settings”.
4.1. - Tmin S(X)
Sensor S(X) switch-on temperature
If the temperature at sensor S(X) exceeds the value of TminS(X) and the other con-
ditions are also met, then the controller switches on the associated pump and/or valve.
If the temperature at the sensor S (X) drops below the value of TminS(X) by 5 °C, then
the pump and/or the valve are switched off again.
Setting range: 0-99 °C /Default setting: 20 °C
The menu is closed by pressing “esc” or
selecting “Exit settings”.

3.4. - Tmax S2
Switch-on/switch-off temperature difference for sensor (X)
If this temperature difference between the reference sensors is exceeded and the
other conditions are also met, then the controller switches on the applicable relay.
When the temperature drops by
Δ T Off, then the relay is switched off again.
Setting range: Δ T: 4 - 50 °C / Δ T off: 2 - 49 °C / Default setting: depends on the hydrau-
lic variant
Setting the temperature difference too small may lead to a situation
when the heat source will not be able to heat up the solar consumer to
the value when the pump is switched off (
Δ T of source – Δ T off). Then
the pump will run continuously. Setting the temperature difference too
big may lead to switching the circulation pump on and off permanently.
Please refer to special rules described in Chapter 6.3 for switching
pumps with controlled speed.
