Theben clock thermostat RAM 722 white, plug-in weekly program - 230 V

• Flat-design clock thermostats for time-dependent monitoring and control of room temperature. Easy setting of the energy-saving night setback on the program dial.
• Suitable for oil or gas heating systems.

The clock thermostat controls, for example, the circulation pump, thermal actuator, solenoid valve, motor mixer or the gas boiler directly via a relay contact.

Inserts or segments allow for lowering several times a day.

Wall construction.
