REG 540/11 fan-coil unit controller

for control of the room temperature using a fan-coil unit in either 4-pipe or 2-pipe version for the heating and/or cooling of a room, with 3 switching outputs (potential-free contacts, rated voltage AC 230 V, rated current 6 A at p.f. = 1) for the control of the fan speed, with 2 switching outputs (semiconductor switches, rated voltage AC 24 V, rated current max. 0.65 A at p.f. = 1, max. continuous load 15 W) for control of small valve actuators over an up to 20 m long cable, with 1 binary input for AC 24 V for connection of a signalling contact (e.g. window contact) over an up to 30 m long cable, with 1 input for connection of the temperature sensor for measuring the room temperature, with setpoint assignment via the EIB, with the operating modes comfort, standby, night and frost or heat protection, selectable over the EIB, with temperature control using a PI-algorithm, with selectable number (1, 2 or 3) of fan speed levels, with optional utilization of unused fan control outputs for switching of lighting, with selection whether an three-step electromotive actuator or an electrothermal actuator is connected to each valve output, with communication objects for the display and operation of the controller over a separate operating device with EIB interface, with controller electronics powered by AC 24 V SELV, with integrated bus coupling unit, bus connection via 2 screw-type terminals, for mounting on DIN rail EN 60715-TH35-7.5 in the fan-coil unit or in a separate small distribution board, width 4 MU (1 MU = 18 mm).
