Room thermostat for control of two-pipe fan-coil units. The thermostat is equipped with a manual heating / cooling switch , a 3-degree fan speed switch and a ventilation function .
Room temperature control in heating or cooling systems. An example is use in commercial and residential buildings or in light industrial installations .
The RAB thermostat can be used in conjunction with zone valves , fans or valves with thermoelectric drives .
Heating – when the temperature drops below the set value, the heating output contact switches on.
Cooling – When the set value is exceeded, the cooling output contact closes.
Winding – When the ventilation function is selected, the valve control valve contacts are permanently open and the fan runs at the preset speed.
Fan speed can be controlled in two ways:
Manually – one of three speeds is set via the switch. In this case, the fan runs continuously.
Automatically – the fan starts when the thermostat is switched on. In this case, the control must change the jumper on the thermostat circuit board before commissioning.
