Fan coil actuator for operation of ventilator convectors (fan coil units), implemented for room air conditioning.
The actuator receives telegrams, e.g. from a room temperature controller, and converts 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, or combined heating and cooling.
2-pipe or 4-pipe operation. 2-pipe system uses a shared water circuit for heating and cooling. 4-pipe system consists of separate supply and return line for the heating and cooling system.
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.
