Room thermostat with clock, surface-mounted
Electronic room thermostat with clock for time-dependent control of temperatures in closed rooms. Suitable for all types of heating. It can be used as a master (pilot controller) to reduce the temperature of other controllers. Controllers of the FETR, FTR and RTBSB series are suitable for this purpose as slaves (satellite controllers).
