Floor Limit Settings
You can set the minimum and maximum temperature that your floor
can reach. These settings are available only if the temperature
control mode setting is at
AF
(refer to section 3.2).
NOTE: The desired ambient temperature might not be attainable if
the maximum floor temperature is set too low.
The thermostat generally turns heating On or Off to control the ambi-
ent temperature. However, if the floor temperature drops below the
set minimum floor temperature limit or rises above the maximum
limit, the thermostat will turn heating On or Off respectively, regard-
less of the ambient temperature, to maintain the floor temperature
within the desired limits.
The minimum and maximum floor temperature
limits are factory-set at 50 °F (10 °C) and 82 °F
(28 °C) respectively. To modify the limits, pro-
ceed as follows:

equipped with a dry contact. When the contact closes, the Unoccu-
pied Mode is activated and the Unoccupied Mode icon
