R3x Wall mounted room thermostat for use in HVAC systems

R3x is an electro-mechanical room thermostat intended for wall mounting. The thermostat contains a pair of gas-filled bellows with a stainless steel membrance which reacts to changes in temperature by generating a movement which is transmitted to a change-over relay. The thermostat can control a heating or cooling function.

The temperature setpoint can be adjusted via the tem­perature wheel. The setpoint range can be mechanically limited.

Main features:

• Cooling or heating function
• Available with on/off or summer/winter switch
• Well-suited for mounting in small and dry areas
