Pulse width modulation (PWM) or two-point control system

Adjustable cycle time (PWM), hysteresis and minimum on/off time (two-point)

Switch-on delay, such as for burners (with two-point control)

Adaptation to valves normally open or closed

Valve protection (as a room temperature controller with and without a limiting function)

Separate resetting of user and installer settings

Heating interruption acc. to EN 50559 adjustable (not for valves opened without power)

The control method depends on the type of heating and is determined by the installer:

Room temperature controller: The heating is turned on when the room temperature falls below the set target temperature (measured with an internal sensor or external remote sensor).

Floor temperature controller: The underfloor heating is turned on when the floor temperature falls below the set target temperature (measured using an external remote sensor).

Room temperature controller with a limiter (in conjunction with underfloor heating): The room temperature is measured and regulated using the internal sensor. An additional external remote sensor is connected to measure the floor temperature, and a target temperature range for the floor is set. The room temperature control is deactivated when the floor temperature is outside of this range. If temperature falls below this range, the heater is turned on, and if the temperature is above this range, the heater is turned off independent of the current room temperature.
