Temperature Sensor
Location
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.
SetPoint 521 Programmable Thermostat User Manual
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.
