The thermostat can operate the heating system based upon either an air
temperature sensor, a floor temperature sensor, or a combination of both the air
and floor temperature sensors together.
Air Temperature Only
If there is only an air temperature sensor (no floor sensor), the thermostat maintains
the 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.
