Heating circuit 1...10 frost protection temperature
If the temperature at the flow temperature sensor of the
heating circuit falls below this value, the heating circuit
pump is started to keep the water in motion.
Heating circuit 1...10 mixing valve Kp
Specifies the gain of the stepped controller for the mixing
valve.
Heating circuit 1...10 mixing valve Tn
Specifies the delay of the stepped controller for the mixing
valve.
Heating circuit 1...10 mixing valve Ty

DHW tank
DHW tank 1...5 DHW tank mode
Defines the function of the DHW tank:
▪ Automatic: The DHW tank is loaded according to the
programme that is set, Legionella heating is released.
▪ Continuous loading: The DHW tank is maintained at the
desired DHW tank temperature continuously (24 hrs),
Legionella heating is released.
▪ Off: The DHW tank and the Legionella heating are
deactivated.
DHW tank 1...5 temperature setpoint
If the DHW tank temperature falls below the value set here
within the set time window, DHW tank loading is released.
If the heat source (boiler or storage tank) has enough
energy, DHW tank loading will remain active until the set
loading increase is reached (“DHW tank loading
temperature minimum difference for loading” parameter).
DHW tank 1...5 loading at lower temperature
If the DHW tank temperature falls below the value set
here, the time window is active and the loading source
(boiler or storage tank) indicates the set loading increase,
and the DHW tank loading is started.
DHW tank 1...5 loading temperature minimum difference
for loading
DHW tank loading only starts within the set time window if
the upper storage tank temperature is greater than the
current DHW tank temperature.
DHW tank 1...5 legionella heating
Specifies the day on which legionella heating should be
completed.
