pump for a while, by choosing

fan and by choosing

6. Additional functions.
To improve comfort in heated rooms, the controller has been equipped with an input
allowing to connect any kind of room thermostat with contact output. When
temperature in the room is below desired temperature, the central heating pump is
turned on and the room thermostat indicator is lit. It means that the boiler should keep
temperature set by the room thermostat knob. After reaching desired temperature in
the room, the room thermostat indicator turns off, the central heating pump is turned
off and the boiler switches to mode in which it keeps burning at minimum temperature.
CAUTION
. In case of not having room thermostat in the system, the room thermostat
input contacts must be short-circuited.
