THEBEN
FCA 2 KNX
KNX fan coil actuator
Product code:
4920210
With the fan coil actuator FCA 2 KNX, Theben presents a fan coil actuator for efficient heating control. It supports 2 and 4 pipe systems and is, for instance, optimally suited for the use in hotel rooms, office buildings, and apartment complexes. Proportionally controllable control valves and fan (0-10 V) ensure precise temperature control. Via the switch outputs, the fan can be controlled in three increments. Two inputs can be used for condensation monitoring and for connecting an external temperature sensor or window contact. The KNX actuator can be used universally for voltages from 100-240 V and 50-60 Hz. Thanks to the adjustable restart delay, small split units can also be controlled.
