Features
- Heating actuator for switching thermal 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.
- Standard protection.
- Feedback via bus e.g. for overload and short circuit.
- Switching the heating circuit pump (standard functions).
- Passive group feedback of the closed servos.

Features
- Fan coil actuator for operation of ventilator convectors (fan coil
units), implemented for room air conditioning.
- The actuator receives telegrams, for example from room
temperature controllers, and converts corrected variable
telegrams into equivalent fan speeds and valve positions.
- Connection of a ventilator convector with up to six ventilator
gradations or connection of two ventilator convectors each with
up to three fan speeds with double pipe systems.
- Manual actuation.
- Building site operation: Outputs can be operated manually
without bus voltage with operating voltage only.
- Operating modes for heating or cooling mode, or combined
heating/cooling mode.
- Double tube or quadruple tube operation. Double tube system
heats or cools via a shared water cycle. Quadruple tube system
consists of separate flow and return for heating and cooling.
- Individual or hierarchic switching of fan speeds.
- Feedback, output indication, block function for each channel,
level limitation.
- Behaviour after bus voltage failure or bus/mains voltage failure
and following an ETS programming process can be configured.
- Limit values can be set.
- Cyclical or event-oriented transmission.
- Free channels can be used for switching functions, e.g. for room
lighting
