Temperature controller, normally closed, with central piece, time-controlled in white, glossy finish. The temperature controller allows for the adjustment of heating needs to individual lifestyles by regulating room temperature based on time of day and day of the week (program), with print. It is suitable for heating or cooling operation and can be used in room and underfloor heating systems. The integrated temperature sensor enables regulation via room and/or external temperature controllers. Additionally, there is a connection for an external floor temperature/remote sensor.

The large, backlit display shows texts, and the operating languages can be set to German, English, Dutch, or French. The controller offers a maximum of 9 switching times per weekday and 3 preset time programs that can be individually customized. Programming can be done with the control panel removed.

It features a switch between manual and automatic operation as well as an automatic summer/winter time switch (which can be disabled). The temperature control range is adjustable, and there is a manual temperature value adjustment. A timer allows for hourly temperature changes, and a holiday program with date activation is also available.

The operating hour counter or energy consumption display is adjustable. The controller offers a valve protection function, frost protection function, and access protection. The control method can be selected between PWM or 2-point (On/Off), and the PWM cycle time as well as the hysteresis (for two-point control) are adjustable. The type of actuator (normally closed/open) is also adjustable. Additionally, the controller features a self-learning heating curve, does not require expansion claws, and has screw terminals. A neutral conductor is required.
