Fan coil actuator for KNX REG plus Features: Fan coil actuator for controlling fan coil units that are used to air-condition rooms. The actuator receives telegrams, e.g. from a room temperature controller, and converts the control variable telegrams into equivalent fan speeds and valve positions. Connection of a fan coil unit with up to six fan speeds or connection of two fan coil units with up to two fan speeds each for 2-pipe systems. Manual operation. Construction site operation: Outputs can be operated manually without bus voltage, only with the operating voltage. Operating modes for heating or cooling operation, or combined heating and cooling operation. 2-pipe or 4-pipe operation. 2-pipe system heats or cools via a common water circuit. 4-pipe system consists of separate flow and return for the heating and cooling system.
