Download PDFThe TF428 RSBS digital thermostat is designed to control a 3-speed fan and valve in OPEN/CLOSE mode in 2 and 4 pipe systems with fan coil units. The RSBS (remote setback) version is suitable for connecting the hotel card module.
In addition to the basic regulation, the thermostat is equipped with a number of other functions: - The CPH function (Cycles per hour) enables more precise control of the desired room temperature - The shutdown function after a set time allows the building administrator to turn off the device, for example, after the end of working hours and thus prevent unnecessary energy consumption during when not needed. - The gradual random start function protects the building's electrical network.
