If your thermostat is being used for radiant floor heating, a floor sensor can be
connected to it. Radiant floors heat the air by raising the floor temperature. Setting
a floor temperature is a way of enhancing the comfort of your living space. There
are two methods to operating the thermostat using a floor sensor.
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. The floor
maximum setting prevents damage to the wood floor from overheating.
