Setting The Temperature

To change the heat temperature setting, push the

buttons to select a

preferred temperature setting.

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 your 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 your

living space while protecting your floor coverings.
