IMPORTANT SAFETY INFORMATION

WARNING:

• Always turn off power at the main power source by unscrewing fuse or switching circuit breaker to the off position before installing, removing, cleaning or servicing thermostat.

• Read all of the information in this manual before installing or programming this thermostat.

• This is a 24V AC low-voltage thermostat. Do not install on voltages higher than 30V AC.

• All wiring must conform to local and national building and electrical codes and ordinances.

• Do not short (jumper) across terminals on the gas valve or at the system control to test installation. This will damage the thermostat and void the warranty.

2. Press either the or button to adjust the temperature setting either up or down.

The display will return to the room temperature display five seconds after the last input and the new setpoint will be saved.

Changing Temperature Differential

IMPORTANT: The temperature differential is factory set at 1 (1°). This means that whenever the room temperature changes by one degree

Fahrenheit from the temperature setting, the system will turn on. If the system turns on too often, increase the temperature differential.

at the same time and hold for one second.

2. Press either the or button to adjust the 1st stage temperature differential up or down.

3. After 5 seconds DIFF will begin to flash on the display indicating 2nd stage differential value.

To Test Thermostat

WARNING: DO NOT SHORT (JUMPER) ACROSS TERMINALS OF GAS VALVE OR

SYSTEM CONTROL TO TEST OPERATION. THIS WILL DAMAGE THE THERMOSTAT AND

VOID YOUR WARRANTY.

CAUTION: D

O NOT SWITCH SYSTEM TO COOL IF THE TEMPERATURE IS BELOW

50°F (10°C).

T

HIS CAN DAMAGE THE AIR CONDITIONING SYSTEM AND CAUSE PERSONAL INJURY

.

1. Place the COOL-OFF-HEAT switch into the COOL position.

2. Press the button until the temperature setting is at least

3 degrees below the room temperature. The air conditioning system should turn on within a few seconds.

COOL-OFF-HEAT

NOTE: When in the COOL mode once the thermostat turns off, a built in 5minute delay prevents the system from turning on again. This protects the compressor. No additional time delay relay is required. To override the 5minute delay for installation, press the RESET button.

COOL-OFF-HEAT

3. Put the COOL-OFF-HEAT switch into the OFF position. The air conditioning system should turn off.

4. Put the COOL-OFF-HEAT switch into the HEAT position.

5. Press the button until the temperature setting is at least

3 degrees above room temperature.

The heating system should turn on.

The fan may not turn on immediately, depending upon the fan delay built into the furnace.

6. Put the COOL-OFF-HEAT switch into the OFF position. The heating system should turn off. The fan may continue to run for a short period of time.

7. Put the AUTO-ON switch to the

ON position. The blower fan should turn on.

8. Put the AUTO-ON switch to the AUTO position. The blower fan should turn off.

Changing Fahrenheit (F) to Celsius (C)

The thermostat is preset to display the temperature in degrees Fahrenheit.

You may change the display readout to Celsius if desired.

1. Move the manual switch marked F (Fahrenheit) and C (Celsius) located at the center of the circuit board to the desired setting (page 5).

2. Press RESET button located to the right of the LCD display to register the change.

The display will change to show the temperature in your desired temperature scale. To return the thermostat to its original setting, repeat steps 1 and 2 above.

Note: Pressing the RESET button resets the 1st and 2nd stage differential to factory preset conditions.

LED Indicator

The LED indicator illuminates during a call for second stage heating or cooling. The auxiliary stages are used to maintain comfort during extremes in weather conditions. If the LED is illuminated too frequently during periods of moderate temperature, check the differential settings

(page 6).

Troubleshooting

Symptom Remedy

Thermostat does not turn on system.

Check wiring.

(See INSTALLATION)

Check fuse. Replace with 2 amp fuse if fuse has opened.

Thermostat turns on and off too frequently.

System fan does not operate properly.

Thermostat does not display proper room temperature.

Increase temperature differential.

(See DIFFERENTIAL)

Move fan option switch to either gas or electric, to match system.

(See INSTALLATION)

Check F Fahrenheit/C Celsius switch located at top center of circuit board for proper position. If a new selection is made, press

RESET button located directly below LCD display.
