IV.4.C.H. Pump Activation Alarm

With this function, you can set the alarm temperature for central heating 

pump activation. The central heating pump is to be activated in case the 

boiler   should   be   overheated,   in   the   water   heater   priority   mode.   The 

pump runs until the boiler temperature drops by 2°C. This protection is 

applied when burnout functions are improperly set.

IV.5.Boiler Alarm Temperature

With this function, you can set the alarm temperature at which the feeder 

and the fan will stop and the central heating pump will be activated in 

order to distribute hot consumption water throughout the system.
