INSTALLATION
Thermostat Location
Install the thermostat approximately 5 feet (1.5m) above the floor in an area that has a good amount of air
circulation and maintains an average room temperature.
Avoid installation in locations where the thermostat can be affected by drafts, dead air spots, hot or cold air
ducts, sunlight, appliances, concealed pipes, chimneys and outside walls.
Warning
Disconnect power before beginning installation.
Install the Sub-Base:
• Remove the sub-base from the body of the thermostat.
• Mount the sub-base as shown below:
Drill 3/16” pilot holes in your
desired location. Use supplied
anchors for drywall or plaster.

3 Installer Manual
Provide Power
• Battery Power - Insert the 2 supplied “AA” type alkaline batteries into the battery compartment located in
the rear housing of the thermostat. Make sure to position the Positive (+) and Negative (-) sides of the
batteries correctly with the +/- symbols in the battery compartment.
• Optional 24 Volt AC power - Connect the common side of the transformer to the C terminal on the
thermostat sub-base. In dual transformer installations, the transformer common must come from the
cooling transformer.
Attach to Thermostat Sub-Base
UP UP

Once you complete the wiring in Section 3, attach
thermostat to sub-base and then configure the
Installer Settings in Section 5.
1) Line up the thermostat body with the sub-base.
2) Carefully push the thermostat body against the
sub-base until it snaps in place.

For use with an external humidifier. Select between disabling humidification, dependent control or independent control.
The DEP setting controls humidification only during a call for heating. The IND setting allows humidification output in the heat
mode, but does not require a call for heating. It is recommended that the IND setting only be used with systems designed for

Detailed Description of Dry Contact Settings (Installer Setting 30)
Condensate COND
Door Switch DOOR
Occupancy OCC
This setting is intended for a condensate pan overflow monitor. When the
contact is active, the thermostat will immediately disable the cooling
compressor(s) and display the message OVERFLOW. After the contact is
inactive for 1 minute, the compressor(s) will resume operation and the
thermostat display will return to normal.
This setting is intended for a door switch monitor. When this mode is
selected, the thermostat will only run the occupied (OCC) portion of the
program schedule while the contact is inactive (door closed). When the
contact becomes active (door open), the thermostat will turn OFF and display
the message DOOROPEN until the contact becomes inactive again. There is a
3-minute delay before the thermostat turns OFF. Temperature override is not
permitted while the contact is active (door open).
This setting is intended for the use of an occupancy sensor or mechanical
spring-wound timer switch. When active, the thermostat will be forced
into the occupied (OCC) portion of the program schedule until the contact
becomes inactive. In setting 32 below, the Occupancy Trigger Control
can be selected (PROG or UNOC).

its normal program schedule until the dry contact is active. When the dry contact is active, the thermostat will only operate
the occupied portion of the program schedule and ignore the unoccupied portion of the program schedule. If UNOC is selected,
the thermostat will ignore the program schedule and always operate in the unoccupied state. When the dry contact is active,
the thermostat will operate in the occupied state for the duration of the contact being active.

Warning
Read Before Testing
• Do not short (or jumper) across terminals on the gas valve or at the heating or cooling system control board
to test the thermostat installation. This could damage the thermostat and void the warranty.
• Do not select the COOL mode of operation if the outside temperature is below 50º F (10º C). This could
possibly damage the controlled cooling system and may cause personal injury.
• This thermostat includes an automatic compressor protection feature to avoid potential damage to the
compressor from short cycling. When testing the system, make sure to take this delay into account.
NOTE: The compressor delay can be bypassed by adjusting Installer Setting 19 - See section 4.

shut down.
4Press the SYSTEM button until the thermostat is in the COOL mode.
5Press the button to lower the set temperature a minimum of 3 degrees below the current room
