Download PDFThe digital thermostat TF428 RSS is designed to control a 3-speed fan and valve in OPEN/CLOSE mode in 2 and 4 pipe systems with fancoil units. An external internal temperature sensor can be connected to the RSS (remote sensor) version.
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.
