4.2.12 Frost protection
Room temperature: Target room temperature in frost protection mode for all heating circuits
Heating limit: If this temperature is exceeded on the outdoor sensor, then all heating circuits in frost
protection mode switch to “Off”
4.2.13 Outputs:
Time delay
Switch-on: Switch-on delay for boiler master-and-slave circuit
Shut down: Switch-on delay for boiler master-and-slave circuit
Temp. difference: Switch-on delay for boiler master-and-slave circuit
In this menu the individual parameters for power output can be set, if under point 4.2.10.1.2 the setting “Boiler sequ
circuit” is selected. The switch-on delay starts to elapse as soon as the actual boiler temperature (forward flow
temperature) drops below the boiler setpoint temperature, minus the boiler temp. differential and the “temperature
difference” of the power output, and a boiler request is present. After the switch-on delay has elapsed the second
boiler is requested. As soon as the forward flow temperature exceeds the described temperature, the switch-off
delay starts running and again cancels the boiler request after the set time.
The output is not set when the input “External 1” is open (stop function). The output is also set when the boiler is
switched off with the “Boiler on/off”, function or if a fault occurs.
