Specifications

1) Dual-Mount Thermostat (Wall Thermostat)
A) Use
The dual-mount thermostat or "wall 'stat" is factory mounted in the unit for setpoint adjustment and
diagnostics. As factory wired, this thermostat is NOT used to sense temperature. This thermostat may
be removed from the unit and remotely mounted. In the remote location, the thermostat may be used
for setpoint adjustment and diagnostics, but it can also be used to sense the space temperature. See
Section 1-E for mounting details and instructions on using this thermostat to sense space temperature.

C) Adjusting Setpoints
The Mode Button and Fan Button are not used.
The setpoint button is used in conjunction with the up/down button to set one of four setpoints. Press
the setpoint button once to get the first setpoint, twice for the second setpoint, etc. Use the up/down
button to increase/decrease the setpoint value. The setpoints are:
Setpoint # Point Range Default Icons Displayed
1 Space Setpoint 65 - 85 °F 74 °F °F
2 Unoccupied Offset 0 - 15 °F 5 °F °F, Unoccupied
3 Minimum Position 0 - 100 % 10 % %, Cool
4 Deadband 1.5-3 °F 2 °F °F
(1) Space Setpoint - Used to calculate the heating and cooling setpoints.
(2) Unoccupied Offset - Used to calculate the unoccupied heating and cooling setpoints. This value is
added to the cooling setpoint and subtracted from the heating setpoint.
(3) Minimum Position - sets the minimum position of the outdoor air damper in terms of damper
actuator position. Value is used only in occupied mode.
(4) Deadband - offset value used calculate the heating and cooling setpoints.
Occupancy Offset = 0°F in occupied mode and Unoccupied Offset in unoccupied mode.
Heating setpoint = Space Setpoint - Deadband - Occupancy Offset. Cooling setpoint = Space Setpoint +
Deadband + Occupancy Offset.
D) Unoccupied Override
A single press of the override button is used to provide a 2 hour unoccupied override. The override LED
is lit during override. The occupancy override may be canceled by pressing the override button for more
than 4 seconds, but less than 8 seconds.
