1. General function
The programmable electronic radiator thermostat Model L
offers a pre-programmed heating and temperature reducing
program. The program can be set individually and it is pos-
sible to control the room temperature in a time-controlled
manner. The device moves a valve to control the flow of
heat to the radiator. The programmable radiator control unit
fits all common radiator valves and is easy to install - wit-
hout discharging the heating water or interfering with the
heating system. The additional Boost function enables the
radiator to be heated up quickly for a brief period of time by
opening the valve for 5 minutes. This gives an immediate
and pleasant feeling of warmth in the room.
