theben FCA 1 KNX Fan Coil Actuator (4920200)

Description

Introduction

The theben FCA 1 KNX (Item no. 4920200) is a dedicated KNX fan coil actuator engineered specifically for controlling fan coil units in modern building automation infrastructure. Operating on an auxiliary mains voltage of 220 V AC – 230 V AC at 50 Hz – 60 Hz along with a KNX bus connection (bus voltage, ≤10 mA), this device supports both 2-pipe and 4-pipe fan coil configurations. This device is part of our professional KNX AC Controller range.

Designed for standard DIN rail mounting with a width of 4 modules, the FCA 1 KNX features Triac contact switching, an additional relay switching capacity of 16, and a blower relay switching capacity of 8. Operating reliably across ambient temperatures from -5°C to 45°C with IP 20 protection and Class II insulation according to EN 60 730-1, it serves as an efficient HVAC control component in KNX networks.
