4. Setup Instructions

1. Unpack the Device: Carefully remove the Autopilot APCET2 thermostat and its components from the packaging.
2. Connect the Temperature Sensor: Plug the 20-foot remote precision temperature sensor into the designated port on the side of the thermostat. Ensure a secure connection.
3. Position the Sensor: Place the temperature sensor in the area where you want to monitor and control the temperature. Avoid placing it in direct sunlight, near heat sources, or in drafts, as this can affect accuracy.
4. Plug in the Thermostat: Insert the 3-prong plug of the Autopilot APCET2 thermostat into a standard 120V AC grounded wall outlet. The Power indicator light should illuminate.
5. Connect Your Device: Plug the heating or cooling device you wish to control into the integrated power outlet on the front of the thermostat.
6. Initial Check: Ensure all connections are secure before proceeding to operation.

5. Operating Instructions

The Autopilot APCET2 offers flexible temperature control with day and night settings and heating/cooling modes.

5.1 Selecting Operating Mode (Heating or Cooling)

• Locate the Heating/Cooling Mode Switch on the front panel (typically marked with flame and snowflake icons).
• Slide the switch to the flame icon for Heating Mode. In this mode, the connected device will turn ON when the temperature drops below the set point and turn OFF when it rises above the set point (considering the +/- 3°F differential).
• Slide the switch to the snowflake icon for Cooling Mode. In this mode, the connected device will turn ON when the temperature rises above the set point and turn OFF when it drops below the set point (considering the +/- 3°F differential).

5.2 Setting Day and Night Temperatures

The thermostat allows for distinct day and night temperature settings.

1. Day Temperature Setting: Use the upper knob (associated with the sun icon) to set your desired daytime temperature. Rotate the knob clockwise to increase the temperature and counter-clockwise to decrease it. The range is 50°F–100°F (10°C–38°C).
2. Night Temperature Setting: Use the lower knob (associated with the moon icon) to set your desired nighttime temperature. Rotate the knob clockwise to increase the temperature and counter-clockwise to decrease it. The range is 50°F–100°F (10°C–38°C).

5.3 Day/Night Detection Mode

The thermostat can automatically switch between day and night settings using its built-in photocell.

• Locate the Day/Night Mode Switch (typically marked with a 24h icon and sun/moon icons).
• Slide the switch to the sun/moon icon for Automatic Day/Night Detection. The built-in photocell will detect ambient light levels and automatically switch between your set day and night temperatures.
• Slide the switch to the 24h icon for 24-Hour Operation. In this mode, the thermostat will continuously use the Day Temperature Setting, regardless of light conditions.

5.4 Memory-Lock Feature

The Memory-lock feature prevents accidental changes to your set points.

• To lock the settings, slide the small switch next to the padlock icon to the locked position. This will prevent the temperature knobs from being accidentally adjusted.
• To unlock the settings, slide the switch to the unlocked position.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your Autopilot APCET2 thermostat.

• Cleaning: Disconnect the thermostat from the power outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners, solvents, or immerse the unit in water.
• Sensor Care: Keep the temperature sensor clean and free from dust or debris. Ensure the sensor cable is not pinched or damaged.
• Storage: If storing the device for an extended period, disconnect it from power, clean it, and store it in a cool, dry place.
