Place the FAN (AUTO/ON) switch in the AUTO position.
Gently pull the cover straight off the base.
Put the thermostat base against the wall where you plan to mount it. (Be sure the wires will feed through the wire opening in the base of the thermostat.)
Mark the placement of the mounting holes.
Move the base out of the way. Drill mounting holes. Use a hammer to tap in the supplied anchors into the mounting holes.
Fasten the base loosely to the wall , using two mounting screws. Place a level against the bottom of the base and adjust until level, then tighten the screws. (Leveling I for appearance only, and will not affect thermostat operation.)
Insert stripped, labeled wires into matching wire terminals. See “Wiring Diagrams”, Section 3,
Tighten screws on terminal block. Gently tug on each wire to be sure of proper connection.
Double check that each wire is connected to the proper terminal
Install two fresh “AAA” alkaline batteries in the battery compartment. Be sure to match positive (+) ends of batteries with positive (+) battery terminals in the battery compartment.
(The thermostat will operate from 2 size “AAA” alkaline batteries or 24VAC power. When operated from 24VAC power, your thermostat will maintain time and continuously display the temperature during a loss of AC power with the batteries installed).
Replace the cover on the thermostat by snapping it in place.
Turn on power to the system at the main service panel.
Test thermostat operation as described in the following section

FAN OPTION SWITCH
Read the following information before setting the fan option switch (See figure 1). If you are unsure of your application, contact a qualified service person. This thermostat is configured from the factory to energize the fan on a call for heat. If your system is an electric heat or heat pump that REQUIRES the thermostat to turn on the fan on a call for heat, place the fan option switch in the ELEC position. If your system does not require the thermostat to energize the fan on a call for heat such as fossil fuel (gas, oil, etc.), forced air system as well as hydraulic heating systems, place the fan option switch in the GAS position.

BATTERY OPERATION
The thermostat will operate from 2 size “AAA” alkaline batteries or 24VAC power. When operated from batteries, connection to the “C” (common) or (neutral) terminal is not required.

NOTE: When operated from batteries only, the LCD display backlight will be lighted less than 5 seconds after each button pressed ,when backlight option are set to 2) or 3).

Wiring Diagrams

CHECK THERMOSTAT OPERATION
If at any time during testing your system does not operate properly, contact a qualified service person.
Turn on power to the system.

Fan Operation

Move the system switch to the OFF position. If your system does not have a “G” (Fan) terminal connection, skip to the Heating System
Move the fan switch to the ON position. The blower should begin to operate.
Move the fan switch to the AUTO position. The blower should stop immediately.

Heating System

Move the SYSTEM switch to the HEAT position. If the auxiliary heating system has a standing pilot, be sure to light it.
When the (FA)st heating cycle rate is selected in the configuration menu, (see configuration menu item 2), the thermostat will call for heat at 0.5ºF (0.5ºC) below set-point, and turn off at set point. When the (SL)ow heating cycle rate is selected, the thermostat will call for heat at 1.5ºF (1.5ºC) below set-point, and turn off at set-point. When the thermostat calls for heat, the display will show Heat On. If the Heat On display is flashing, the compressor lockout feature is operating in the heat pump mode. (Note: See Configuration menu item 8).

Cooling System

Move the SYSTEM switch to the COOL position.
When the (FA)st cooling cycle rate is selected in the configuration menu, (see configuration menu item 2), the thermostat will call for cooling at 0.5ºF (0.5ºC) above set-point, and turn off at set point. When the (SL)ow cool cycle rate is selected, the thermostat will call for cooling at 1.5ºF (1.5ºC) above set-point, and turn off at set-point. When the thermostat calls for cooling, the display will show COOL On. If the COOL On display is flashing, the compressor lockout feature is operating. (Note: See Configuration menu item 8).

Replacing Batteries
If your thermostat was pre-installed, the batteries may be in place. If the battery icon on the display is flashing, it indicates that the batteries need to be replaced. When the thermostat is powered only by battery, the battery icon will flash for approximately 2 months before the batteries are expected to expire. Then the thermostat will cut power to the heating/cooling system. Important: Replace the batteries when the low battery message flashes on the display. This will keep the thermostat operating properly. With two “AAA” batteries installed, your thermostat will maintain time and continuously display the temperature during a loss of AC power.

Place the COOL/OFF/HEAT switch in the OFF position.
Put the FAN AUTO/ON switch in the AUTO position.
Gently pull the cover straight off the base.
Install two “AAA” alkaline batteries in the battery compartment. Be sure to match the positive (+) ends of the batteries with the positive terminals marked in the battery compartment.
It may take as long as 30 seconds of operation for the Low Battery icon to disappear after changing batteries
