RTBSB-201.065/02
Room thermostat, surface-mounted super flat, 5…30…°C, 230V AC, 2(1)A, two-way contact, heating/cooling switch, scale *…6
Electromechanical room thermostat in super-flat surface-mounted housing (only 13.9mm deep) for controlling or monitoring temperatures in offices, living rooms, and hotels. The thermal feedback achieves a very accurate switching differential. The setting range can be changed with the range restriction located under the setting knob. The unit is mounted by means of surface/wall mounting (4-hole fastening on the flush-mounted box).
Suitable for 2-pipe systems, especially heat pumps. Heating/cooling changeover is performed via a switch on the device.
