Before making a purchase, ensure that the product is suitable for your system and verify its dimensions to determine if it can conceal the marks left by the previous thermostat installation.
The Aowel AW721 is a non-programmable heat pump thermostat designed for residences with up to 2 heating stages and 1 cooling stage.
It is compatible with heat pump systems (including those with auxiliary or emergency heating) and standard heat pumps without backup heat, accommodating up to 2 heating stages and 1 cooling stage. Make sure to access the menu to initialize the heat pump system.
This thermostat is also compatible with a wide range of 24V conventional single-stage systems, such as forced air, central gas, oil, and electric furnace systems, supporting up to 2 heating stages and 1 cooling stage. Please note that you must adjust the menu settings to operate with conventional systems.
**Important Notes:**
1. This thermostat does not function with conventional multi-stage systems, mini-split systems, or 12V RV thermostats.
2. It is not compatible with 110-240V electric heating systems, including electric baseboard heaters, line voltage systems, convectors, and radiant ceiling heaters.
The device is powered by either 24VAC or 2 AAA batteries, and it typically does not require a common wire (c-wire) for most setups, though it may be necessary for heat-only or cool-only systems.
Featuring a clear 5.0 square inch display with a white backlight, the large, illuminated digital readout is especially user-friendly for older adults. It shows both indoor temperature and humidity levels.
This digital thermostat offers separate swing settings for heating and cooling (Cycle Rate), with a default of 0.5°F (adjustable from 0.2°F to 2°F) and includes a 3-minute compressor delay feature (selectable ON or OFF) as well as a low battery replacement alert.
It supports error correction for ambient temperature readings, providing accurate temperature control within +/- 1°F for consistent comfort. The room temperature display range is from 32°F to 99°F, while the adjustable temperature control range spans from 44°F to 90°F.
We provide friendly service with a 2-year warranty and 24-hour customer support. (Tip: Before buying, please verify that the wiring connections of your old thermostat are compatible.)
