RCF230TD Fan Coil Thermostat
Description
RCF230TD Fan Coil Thermostat
RCF230TD electronic thermostat for automatic fan speed control and electrically operated valve control in 2- or 4-pipe fan coil systems or small air conditioners.
The thermostats are equipped with digital input for economical or stand-by mode, which can be activated remotely or on its own switch, from a window contact or from an access card.
P + I control (proportional + integral) with on / off drive signal or PWM (pulse on / off modulation) on 2 or 4 pipe fan coil units.
In 2-pipe fan coil units, the thermostats can control a motorized mixing valve with a floating proportional control signal.
The EPROM memory ensures that the settings are maintained in the event of a power failure.
The thermostat can be adapted to the particularities of the application using the 38 configurable parameters.
Heat actuators / actuators are operated daily to prevent seizure.
Fan speeds change automatically depending on the deviation from the reference temperature, with continuous operation or automatic shutdown in the dead zone area (adjustable).
Supply voltage: 230V AC; Power consumption: 3 W (internal electronics), Protection class: - IP20
Display: liquid crystal, illuminated, light blue, dimmable. Display indications: thermometer, reference temperature, open window, operating mode (heating or cooling), service, operating mode (comfort / eco / standby), fan off / auto / manual 1, 2, 3.
Forms of control: P + I with on / off actuation - PWM (modulation by on / off pulses) for on / off thermoelectric actuations in systems with 2 or 4 pipes; P + I with proportional-floating actuation for servomotors mounted on mixing valves in 2-pipe systems
Configurable parameters: 38, for perfect adaptation to the specifics of the application
Internal sensor: NTC (piping sensor mount cancels internal sensor)
Adjustment range: + 5… + 35 ° C
2-pipe operating modes: heating, cooling or heating and cooling with automatic passage using pipe / thermostat sensor or configuration by changing a parameter
4-pipe operating modes: automatic heating and cooling
Optional external sensor: Pt1000 (ambient TG-R5, TG-KH or TG-K3 piping)
Occupancy contact: digital, for presence detector, contact card or window
Fan outputs: 3 relays 230 V ac / 3 A, for auto / man speed control. 1,2,3
Valve motor control outputs: 2 digital (triac), 230 V ac / 300 mA max., 20A for max. 2 ms, for control 2 on / off thermal actuations, or optionally a mixing valve with floating proportional servomotor (only 2-pipe systems)
