Control relay FCRY 3
Produal FCRY 3
Three-speed fan-coil control relay via 0-10 Vdc signal. Internal interlocks prevent simultaneous switching. Typically used with a room controller.
FCRY 3 is a 3 speed fan coil control relay, with 0..10 Vdc control input. Adjustable switching voltages and hysteresis. 24 Vac/dc power supply. 3 x 230 Vac 8 A relays. Internal interlocks prevent simultaneous switching. Often used with a room controller.
With this accessory, you can modify or add new controllers to an installation without replacing the fan coils or, when integrating 3-speed fans into an existing system, do so easily.
Speed selection is done automatically according to the voltage. These parameters are adjustable, but the factory settings are as follows:
RL1 set point: 2.5 V (speed 1) RL2 set point: 5.0 V (speed 2) RL3 set point: 7.5 V (speed 3) Hysteresis: 0.5 V
It connects directly to the fan motor, avoiding complex modifications to the electrical installation.
