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 prevent unnecessary energy consumption when it is not needed. - The gradual random start function protects the building's electrical network.
