Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must be
provided by the customer!
Other values, for example, Teco, apply in economy mode.
DHW request
Thermostat is started for a DHW - heat request.
Heating Circuit request
Thermostat is started with a heating circuit - heat request.
Tset
The target temperature of the thermostat sensor 1. Below this temperature, the thermostat turns on until Tset+ Hysteresis is reached.
Hysteresis
Hysteresis of set point temperature.
Energy Saving Mode
The Energy Saving Mode switches the heating on when “T Eco on” is undershot and heats up to “T Eco” + hysteresis when solar charge
or solid fuel boiler is active.
Delay
Delay for this function.
The function first turns on after this time span if the switch conditions were reached and are still present. This delay is intended to pre-
vent unnecessary switching operations caused by temperature fluctuations or to
Give another energy source time to provide the necessary energy.
Thermostat sensor 1
TH Set is measured at thermostat sensor 1. With a connected thermostat sensor 2, the relay switches on if “TH Ref” at thermostat sensor
1 is undershot and off if “TH Ref” + hysteresis is exceeded at thermostat sensor 2.
Thermostat sensor 2
Optional switch off sensor
If “TH target” + hysteresis is exceeded on thermostat sensor 2, the relay will be shut down.
Thermostat enable
Thermostat activity times
Here the desired periods are set in which the thermostat function is approved. For each weekday, three times can be specified, fur-
thermore, you can copy individual day to other days. The thermostat function is shut down outside of the set times.
Electric heating rod (auxiliary heating)
An electric heating rod that heats up the storage water heater if needed. The heating rod function can be used in 2 modes. "On" = the
relay is switched on when all switching conditions are reached.
"Inverted" = the relay is switched off when all switching conditions are reached and is otherwise switched on.
Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must be
provided by the customer!
DHW request
Electric heating rod is started for a DHW - heat request.
HC request
Electric heating rod is started with a heating circuit - heat request.
TH Set
The target temperature of the thermostat sensor 1. Below this temperature, the eat turns on until TH Set + Hysteresis is reached.
Delay
After reaching the switching conditions, the time set here will be waited until the heating rod is actually turned on in order to give another
heat source time to heat up.
