Temperature Limiting
Note:
This feature is not available with the Remote
Thermostat ― Class 2.
Temperature limiting can reduce energy costs by
limiting the lowest temperature that can be set for
cooling and the highest temperature that can be set
for heating. Temperature limiting is controlled by the
right-hand set of auxiliary switches, # 1 through #6.
The fi rst 3 switches are used to select the cooling
limits, and the remaining 3 switches are used to
control the heating limits.
Heat Sentinel
When this switch is enabled (UP), it turns on the heat
sentinel protection feature. With the switch disabled
(down position), the heat sentinel is deactivated. This
feature automatically provides cooling without user
interface. This helps to prevent an excessively hot
room by turning the air conditioner ON at 85°F and
OFF at 80°F. The heat sentinel will remain enabled
when the unit has been turned off by the remote
CDC. The heat sentinel is functional with a wall
thermostat as well.
Heat Boost (3800 Series only)
When this switch is enabled (UP) and outdoor
temperatures are between 20°F and 46°F, the heat
pump-only operation is locked out. This setting is
used to provide supplementary heat to the heat
pump operation in conditions where the heat
pump-only operation is not suffi cient to maintain a
consistent, comfortable room temperature.
Note:
This is an auxiliary switch for 2800 Series
models and must remain in the down position.
