20. The COMFORT SYSTEM function
21. The protection against freezing function
22. Protection of the boiler against overheating
The COMFORT SYSTEM built-in in the controller prevents pump blockage by
deposition of scale between the rotor and stator of the pump. The controller
automatically switches the pump on for 30 seconds every 24 hours from its last
run. Pump operation in this mode is indicated by the blinking LED CH PUMP The
function takes effect after 24 hours from turning the controller on.
Note:
For the COMFORT SYSTEM function to be active after
the end of the heating season, leave the controller plugged in.
The controller reduces the risk of overheating the boiler through the continuous
operation of the pumps in the event of the boiler temperature sensor failure or if
the alarm temperature for both pumps is exceeded - see Alarm - pump
temperature
The controller protects the heating system from freezing, both pumps running all
the time when the temperature of water falls to 4 °C or lower (DHW pump will
start, provided that the controller runs in the DHW mode).
