As a wire-guided mechanical room thermostat, the room temperature controllers are directly wired to a heating element. The wall unit is suitable for surface mounting. Eco-design-compliant use in conjunction with stationary infrared heating elements is not possible. Setting range 5-30°C, reduction, on/off switch, heating lamp, break contact, 230VAC, 10A, pure white similar to RAL 9010, operating voltage: 230 VAC, 50 Hz, hysteresis: approx. 0.5 K with a temperature change of max. 4 K / h, max. switching current: 10 A (2.2 kW), switching element: bimetal contact, on/off switch: yes, switching contact: break contact (max. 10 actuators), switching capacity: 2300 W, protection type: IP 30, protection class: II, dimensions 78x82x27mm. If the installed power exceeds the specified switching capacity of the respective room thermostat, the heating elements must be switched via additional load relays type LS-E.
