===== General description =====

FC-1-IQ is main actuator for TH units. It can drive fully featured fan-coils for wide range of convectors with electromechanical valves and 3 speed fan motor It can be used for controlling practically any heating/cooling system including: hot-water radiator valve, ceiling fan, ceiling/floor heating valve, electrical radiator power relay and AC’s.
