Heating actuator for switching electrothermic servos for heating or cooling ceilings.
Control using 1-bit or 1-byte corrected variable telegrams.
For 1-byte correcting variables, the outputs are controlled by pulse width modulation (PWM).
Servos with the characteristic "de-energised open" or "de-energised closed" can be controlled.
Servos can be activated with rated voltage 24 V or 230 V.
Overload protected, short-circuit protected.
Feedback via bus e.g. for overload and short circuit.
Switching the heating circuit pump (standard functions).
Passive group feedback of the closed servos.
