In Temperature andTimer mode, it acts as a 4-stage run-back timer where the heating period will be active until the run-back timer expires. There is a choice of three time periods available: 5, 15 or 30 minutes. When the button is pressed four times, this takes the run-back time period to 20, 60 or 120 minutes. Target room temperature can be set using the temperature control buttons.
In Temperature Control mode, it features temperature control for comfort and setback periods which can also be used in conjunction with the Timer mode.
