2. Place the FAN switch in the AUTO position. (See Figure 2)

3. Push the button on the bottom of the thermostat and gently pull the front cover straight off

the base. (See Figure 3A)

4. Using thermostat base, identify the placement of the thermostat on the wall or junction box.

Ensure that the base is oriented so that the button latch (from step 3) is at the bottom, and

feed the wires through the wire opening in the base.

5. Using the mounting screws (and anchors) provided, mount the thermostat base loosely to

the wall or junction box. (See Figure 3B)

6. Place a level against the bottom of the base and adjust until level, then tighten the screws.

(Leveling is for appearance only and will not affect thermostat operation.)

7. Insert stripped, labeled wires into matching wire terminals. (See Figure 4 below)

CAUTION: Be sure exposed portions of wires do not touch other wires.

WIRING DIAGRAMS

Notes:

* Auxiliary and emergency heat operate from a single relay, and the “AUX” and “E” terminals may

be jumpered as necessary.

‡Reversing valve activates in cooling when wired to the “O” terminal and activates in heating when

wired to the “B” terminal.

The common must be connected to operate the system. If batteries are installed, they will only

maintain the clock during power outages.

CONFIGURATION MENU CHART

See “Parameters” section for a detailed explanation of parameters and values.

PARAMETERS

CC - Select Cooling Cycle Rate

The FA setting produces shorter cooling cycles. The SL setting produces longer cooling

cycles. FA cycles the system at a 0.75ºF differential (0.5°C), and SL cycles the system at a

1.5ºF differential (1°C).

HC - Select Heating Cycle Rate

The FA setting produces shorter heating cycles. The SL setting produces longer heating

cycles. FA cycles the system at a 0.75ºF differential (0.5°C), and SL cycles the system at a

1.5ºF differential (1°C).

CP - Select Compressor Lockout Delay

To protect the compressor from short cycling, you can select the minimum length of time the

compressor will turn off between cycles from 0 to 5 minutes in 1 minute increments. When a

compressor lockout delay occurs, “COMP DELAY” will flash.

AU - Select Auxiliary Heat Offset

This feature allows you to select when the auxiliary heat system will turn on. This offset can

be set from 1 to 10 (degrees), in 1°increments, and the auxiliary system will turn on (in

addition to first stage of heat) when the room temperature is below the setpoint by the

selected number of degrees plus heating cycle rate value (HC). For example, if 4 is selected

for the auxiliary heat offset and SL is selected as the heating cycle rate, the auxiliary heat will

turn on when the room temperature shows 6°below setpoint:

4°for offset + 1.5°for SL cycle rate = 5.5°(rounded to 6°on thermostat display)

bL - Select LCD Backlight Duration

The LCD backlight improves display contrast in low lighting conditions. Select 1 for no

backlight. Select 2 for the backlight to come on for approximately 30 seconds when any

button on the thermostat is pressed. Select 3 for the backlight to remain on continuously.

FL - Select Filter Service Time

The thermostat will display “SERVICE FILTER” after a set time of operation. This is a

reminder to clean or replace your air filter. This time can be set from 1 to 12 months in 1

month increments. Note: 1 month = 30 days, and the number of days is also displayed in the

upper left corner of the LCD. A selection of 00 will deactivate this feature. When “SERVICE

FILTER” is displayed, in EMH, HEAT or COOL mode it can be cleared by pressing the ▲

and ▼ buttons at the same time. This resets the timer and starts counting down the days

until the next filter service.

FC - Select ºF or ºC Temperature Scale

Selects the temperature scale to be displayed –(F)ahrenheit or (C)elsius - as desired.

CL - Select Temperature Calibration Value

This feature allows you to adjust the displayed room temperature from 1°to 4ºhigher or

lower than the actual room temperature. Your thermostat can be accurately calibrated to

match your previous thermostat. The temperature displayed will reflect the adjusted

temperature. Select 0 if no calibration is desired.

SYSTEM CHECK

If at any time during testing your system does not operate properly, contact a qualified HVAC

contractor.

Ensure that there is power to the system.

Fan Operation

(If your system does not have a “G” (Fan) terminal connection, skip to the “Heating System”

section.)

1. Move the SYSTEM switch to the OFF position.

2. Move the FAN switch to the ON position. The blower should begin to operate.

3. Move the FAN switch to the AUTO position. The blower should stop immediately.

Heating System

1. Move the SYSTEM switch to the HEAT position. If the auxiliary heating system has a

standing pilot, be sure to light it.

2. Adjust the setpoint to a temperature above the current room temperature.

If the (FA)st heating cycle rate is selected in the configuration menu (see “Configuration

Menu Chart”), the thermostat will call for heat when the room temperature is 0.75ºF (0.5ºC)

below setpoint and turn off at setpoint.

If the (SL)ow heating cycle rate is selected, the thermostat will call for heat when the room

temperature is 1.5ºF (1ºC) below setpoint and turn off at setpoint.

The auxiliary heat will activate when the room temperature is below the setpoint by the

auxiliary heat offset value (AU) plus heating cycle rate value (HC), as established during

configuration. When auxiliary heat turns on “AUX” will be displayed. (See “Configuration

Menu Chart”, “Parameters”, and Figure 1.)

* Note: Auxiliary heat will only activate in conjunction with the compressor and fan and

therefore will be affected by compressor lockout delay settings. (See “Configuration

Menu Chart”) Once activated, auxiliary heat will continue to run until the room

temperature is less than 2°F (1°C) below setpoint, and the first stage of heat will

complete the call.

3. When the thermostat calls for heat, will display. If is not displayed and “COMP

DELAY” is flashing, the compressor lockout delay feature is operating in the heat pump

mode. (See “Configuration Menu Chart”)

Emergency Heating System

The Emergency Heat System bypasses the heat pump to use the heat source connected to

terminal “E” on the thermostat. It is typically used when compressor operation is not desired or

you prefer to use the backup heating system only.

1. Move the SYSTEM switch to the EMH position. “EMH” will flash on the display as long as

- 9 -

the switch stays in this position.

2. Adjust the setpoint to a temperature above the current room temperature.

If the (FA)st heating cycle rate is selected in the configuration menu (see “Configuration

Menu Chart”), the thermostat will call for emergency heat when the room temperature is

0.75ºF (0.5ºC) below setpoint and turn off at setpoint.

If the (SL)ow heating cycle rate is selected, the thermostat will call for emergency heat

when the room temperature is 1.5ºF (1ºC) below setpoint and turn off at setpoint.

3. In emergency heat mode, “AUX” will display when the thermostat is in a call for heat.

Note –will not display.

Cooling System

CAUTION: To prevent compressor and/or property damage, if the outdoor temperature

is below 50ºF (10ºC), DO NOT operate the cooling system.

1. Move the SYSTEM switch to the COOL position.

2. Adjust the setpoint to a temperature below the current room temperature.

If the (FA)st cooling cycle rate is selected in the configuration menu (see “Configuration

Menu Chart”), the thermostat will call for cooling when the room temperature is 0.75ºF

(0.5ºC) above setpoint and turn off at setpoint.

If the (SL)ow cooling cycle rate is selected, the thermostat will call for cooling when the

room temperature is 1.5ºF (1ºC) above setpoint and turn off at setpoint.

3. When the thermostat calls for cooling, will display. If is not displayed and “COMP

DELAY” is flashing, the compressor lockout delay feature is operating. (See “Configuration

Menu Chart”)

Equipment Monitor

The “L” terminal on the thermostat allows for an equipment monitor input. For example, a

compressor drip pan overflow alarm could be wired. When a 24 VAC signal is sent to the “L”

terminal, the thermostat will flash “SERVICE” on the LCD to indicate that action is required.

Contact your HVAC contractor for details on what may be wired to the “L” terminal.

If all functions listed above operate properly, the thermostat is installed correctly.

BASIC THERMOSTAT OPERATION

Setting the Thermostat

1. This thermostat is very easy to operate. Move the SYSTEM switch to either EMH, HEAT, or

COOL, then press either the ▲ or ▼ button to adjust the setpoint to the desired value.

2. Move the FAN switch to either AUTO or ON. AUTO will run the fan only when the

thermostat calls for heating, emergency heating (depending on the position of the FAN

OPTION switch –see page 5), or cooling. ON will run the fan continuously. Note –

continuous fan will run in EMH, HEAT, COOL, and OFF system settings.

1. Move the SYSTEM switch to the EMH, HEAT, or COOL position, then press and hold the ▲

and ▼buttons at the same time for 5 seconds to enter the filter review mode. (Note –When

“SERVICE FILTER” message is displayed and after filter has been cleaned or replaced, this

same process is used to clear “SERVICE FILTER” message.)

2. The number of days left until filter cleaning or replacement will be displayed.

3. Press either the ▲or ▼button one time to exit the filter review mode. If no buttons are

pressed within 15 seconds, the thermostat will exit to normal operation.

4. In filter review mode, press and hold the ▲and ▼buttons at the same time to reset the

amount of time until the next filter service. The display will flash “dEF”to indicate that reset

has been completed, unless FL has been deactivated, selection 00. (See “Configuration

Menu Chart”)
