KNX fan coil actuator

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
