Auxiliary Temperature/Outdoor Air Sensor
Calibration (Cal OS)
An offset can be added or subtracted to the actual
displayed auxiliary/outdoor air temperature as needed.
The range is ±5.0 F° (±2.5 C°), adjustable in
increments of 1 F° (0.5 C°).
To change the sensor calibration/offset while in the
Installer Configuration Menu:
1. Answer NO to all prompts until the
auxiliary/outdoor sensor calibration prompt
appears in the display. Press YES to enter the
auxiliary/outdoor sensor calibration menu.
2. Use the UP/DOWN arrow keys to adjust the

Setting the Heating Lockout (H lock)
This feature disables heating operation based on
auxiliary or outdoor air temperature (requires
temperature sensor to be connected to the
Auxiliary/Outdoor Air Sensor terminal OS for the
function to be enabled). If the outdoor air temperature
is above the heating lockout temperature, heating
operation is disabled.
The heating lockout temperature parameter is
adjustable from -15 to 123°F (-26 to 51°C) in
increments of 5 F/C°.
IMPORTANT:
Setting the heating lockout to
123°F (51°C) disables the heating lockout feature.
If this parameter is being set at 123°F (51°C) to
monitor discharge air temperature or temperatures
above 122°F (50°C), note that the maximum
temperature displayed for auxiliary temperature during
operation is 122°F (50°C). The actual temperature
may be above this point.
To change the auxiliary/outdoor air temperature
heating lockout while in the Installer Configuration
Menu:
1. Answer NO to all prompts until the heating lockout
prompt appears in the display. Press YES to enter
the heating lockout menu.
2. Use the UP/DOWN arrow keys to adjust the
lockout temperature. Press YES to store the value.
The display now shows the cooling lockout prompt.
See the Setting the Cooling Lockout (C lock) section
for instructions.
Setting the Cooling Lockout (C lock)
This feature disables cooling operation based on
outdoor air temperature (requires outdoor air
temperature sensor to be connected for the function to
be enabled). If the outdoor air temperature is below
the cooling lockout temperature, cooling operation is
disabled.
The cooling lockout temperature parameter is
adjustable from -40 to 95°F (-40 to 35°C) in
increments of 5 F/C°.
