Heating Operation
Sequence of Operation
To change the heat temperature setting, push the or button to select a preferred
temperature setting. The Heat On symbol is shown on the display when the thermostat is
heating. The heat can cycle on and off /- 1.5°F (1°C) of the temperature setting.
The floor and air heating can be shut off by holding the button until Set Room is Off.
To resume heating when the Mode is Off, press the button to navigate to the Mode
setting, then press the button to select Mode Heat. The thermostat will resume heating at
the last previously set temperature.
Air Temperature Only
-----------------------------
If there is only an air temperature sensor (no floor sensor), the thermostat operates to control
your desired air temperature.
Floor Temperature Only
----------------------------
If the air sensor has been disabled, the thermostat will only maintain floor temperature and
ignore air temperature. This operation is recommended for areas such as bathrooms to ensure
that tile floors are warm to the touch.
Floor and Air Temperature
---------------------------
If the air sensor is turned on and a floor sensor is connected, the thermostat will maintain the
desired air temperature as well as a minimum floor temperature.
This operation is recommended for areas with large windows that allow the sun to shine into a
room and keep it warm without the need for heat. This can allow the floors to cool off during the
afternoon. When the sun goes down, it can take a long time for the floors to get warm again.
This may cause the room to cool off too much in the early evening. A floor minimum setting can
help with this condition by maintaining a floor minimum temperature. Keep in mind the floor
minimum temperature will override the air temperature, and if set too high, may overheat the
room.
This operation is also recommended for rooms with hardwood floors. Setting floor minimum
and maximum temperatures is a way of enhancing the comfort of the living space while
protecting floor coverings.
