Use the System switch to place the system in one of the following modes:

• Cool: The system is in Cooling mode.
• Off: The system is off.
• Heat: The system is in Heating mode.

CAUTION: EQUIPMENT DAMAGE HAZARD.
Do not use Cooling mode when the outdoor temperature is below 50°F (10°C).

Fan switch (Auto/On)

Use the Fan switch to select the fan operation.

• Auto: The fan runs only when heating or cooling is activated (commonly used setting).
• On: The fan runs continuously.

Built-in compressor protection

Your thermostat has a feature that helps prevent damage to the compressor of your air conditioning or heat pump system. Because damage can occur if the compressor is restarted too soon after shutdown, this feature forces the compressor to wait 5 minutes before restarting. During the wait time, the message Cool On or Heat On flashes on the screen. When the safe wait time has elapsed, the message stops flashing and the compressor turns on.

Battery replacement

Set the System switch to Off before removing the batteries. Otherwise, the heating/cooling system could remain activated even when the batteries are removed.

Install two fresh AAA batteries when Lo Batt flashes on the screen. Lo Batt appears for 60 days before the batteries are depleted.
Replace batteries once a year, or when you will be away for more than a month.
The settings are stored in non-volatile (permanent) memory and are thus preserved when the thermostat is without batteries.

In case of difficulty

• The screen is blank.
  Ensure two fresh AAA alkaline batteries are correctly installed.
• Temperature settings cannot be changed.
  • The System switch is off.
  • You are setting the temperature outside its allowable range:
  • Heat: 40°F to 90°F (4.5°C to 32°C)
  • Cool: 50°F to 99°F (10°C to 37°C)
• Cool On or Heat On is flashing.
  The compressor protection delay is underway. Wait for the delay to end (maximum of 5 minutes).
• HI appears on the screen.
  The ambient (measured) temperature is above 122°F (50°C).
• LO appears on the screen.
  The ambient (measured) temperature is below 32°F (0°C).
• E1 appears on the screen.
  The temperature sensor circuit is opened. Replace the thermostat.
• E2 appears on the screen.
  The temperature sensor circuit is shorted. Replace the thermostat.
