The 5-piece set Model L electronic radiator thermostat with boost function offers simple installation without interfering with the heating system and fits almost all valves. The intuitive operation and large display make handling particularly user-friendly. It also has practical functions such as automatic lowering when ventilating, a child safety lock and frost protection and anti-scale functions. The battery life is around 3 years. The holiday and party functions, which can be used to maintain a set temperature for a certain period of time, are particularly useful. The programmed switching cycles are overridden and the regular settings automatically apply again once the set time has elapsed.
