Download PDFThe digital thermostat TF428 RSS is designed to control a 3-speed fan and valve in the OPEN/CLOSE mode in 2 and 4 pipe systems with fan coil units. The RSS version (remote sensor) allows connection of an external indoor temperature sensor.
In addition to basic regulation, the thermostat is equipped with a range of other functions: - CPH function (Cycles Per Hour) allows for more precise control of the desired room temperature - The timed shutdown function allows the facility manager to turn off the device for example after working hours and thus prevent unnecessary energy consumption when it is not needed. - The gradual random start function protects the building's electrical network.
