ADVENT AIR ACTH12 Digital LCD Thermostat Instruction Manual Overview

Summary of Contents

Page 1: Page 1
Page 2: Features include digital communication, a liquid crystal display with room and set temperature, and blue LED illumination. The device has individual LEDs for each mode and offers both Fahrenheit and Celsius display options. It is compatible with cooling, heat pumps, heat strips, and furnaces. To operate, press and hold the designated button for 3 seconds to turn the system on or off. You can select the desired mode and room temperature by pressing the respective buttons. The fan setting and speed can also be adjusted. The temperature format can be changed from Fahrenheit to Celsius by pressing and holding two buttons together for 3 seconds. The room temperature range is 32°F to 99°F, while the set temperature range is 60°F to 86°F. Fan operation allows cycling through available settings, with the fan running in auto mode based on the temperature difference between room and set temperatures. In the cooling operation mode, the compressor cycles on and off based on the room and set temperature.
Page 3: Heat pump operation involves the compressor cycling On/Off based on the room/set temperature. The fan runs first, followed by the compressor after approximately 3 minutes. If the outdoor temperature is below 38°F, the heat pump will not work, and the thermostat will activate the furnace as the main heat source. The fan continues to run as set. Once the outdoor temperature rises above 45°F, the thermostat switches back to the heat pump. If the heat pump runs for more than 20 minutes and the room temperature is below 64°F, the thermostat activates the furnace. Heat strip operation cycles On/Off based on the room/set temperature, with a 20-second fan delay for heat buildup. The heat strip shuts off once the room temperature reaches the set temperature, and the fan runs for an additional 30 seconds to blow residual heat. Furnace operation involves the thermostat providing a 12VDC trigger to activate the RV furnace. The fan settings can be selected as Auto, On High/Medium/Low, or Off. In Auto mode, the fan runs for 30 seconds after reaching the set temperature. The thermostat error code table is included for troubleshooting. A factory reset can be performed by starting with the thermostat in Off mode and pressing specific buttons to reset to factory settings.
Page 4: Maintenance Use a moist, soft cloth to clean the thermostat. Do not spray water or solvents on the thermostat. Frost may form on the indoor coil under certain conditions. Inspect the filter and clean if dirty. Make sure air louvers are not obstructed. Air conditioners/heat pumps may frost when the outside temperature is low. Adjust the thermostat control to a warmer setting to prevent frost. Service If the unit does not operate, check the generator or shore power connection. Ensure the supply breaker is sized properly for the air conditioner/heat pump load. Check your fuse or circuit breaker to see if it is off. Call your local service center for further help; the unit must be serviced by qualified personnel. Important warranty information Do not return defective product to your place of purchase.
