The heating actuator can control 230V thermoelectric actuators for up to 12 different heating/cooling zones. It can be installed directly in the heating distribution box and requires a 230V mains supply. It is primarily used for controlling surface heating/cooling systems (e.g. underfloor heating), but is not limited to this. It receives the setpoint and actual values from the Room Controller, Room Manager or Home Manager. The heating actuator has an integrated pump control/heat request, whereby the heating pump/heat generator can be connected both locally and via a radio switching actuator. The option of external switching via a change-over signal makes this control system suitable for heating and cooling in single-circuit systems. The cooling function can be interrupted if condensation occurs using a dew point sensor. The device is suitable for NC or NO systems.
