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.
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
