by comparing the set temperature with the actual room temperature and comparing the preset floor temperature
limit with the actual floor temperature. The factory default maximum floor limit is 40℃or 104℉. You can change it
in configuration menu item 4. Assuming that the floor temperature is below the maximum floor temperature limit,
the heating should begin to operate if the set temperature is 1℃or 2℉ higher than the actual room temperature.
Mode
is room sensor control mode.
