KNX DRA fan coil act. [216300] Fan coil actuator for KNX Heating, ventilation, air conditioning DRA Features: - 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.
