Smart Thermostat, 7 Day Programmable WiFi Thermostat for HVAC, APP & Voice Control

Effortlessly control the temperature of your home from anywhere with the MechDoc smart WiFi thermostat. It's our goal to bring you convenience for your daily life.

Compatible Systems: - Works with 85% of systems, including single-stage 1 Heat and 1 Cool HVAC systems (gas, oil, electric furnaces, heat pumps without aux heat, cool/heat only systems) - Not compatible with 110V/220V systems - Before purchasing, check the wiring diagrams in the #4 main image to ensure compatibility with your system - Our thermostat supports conventional systems and heat pump systems with no more than 6 wires (RC, RH, C, G, W/O/B, Y) - Take a photo of the wire connections for reference when replacing your old thermostat, and label each wire as you disconnect it

Power Requirements: - 24VAC power supply is required - C-wire is the primary power source and is necessary for the thermostat to function - Battery power is not supported - If your system doesn't have a C-wire, you'll need to install a C-wire power adapter (sold separately)

Smart Home Integration: - This 7-day programmable smart WiFi thermostat is compatible with Amazon Alexa and Google Assistant

Energy Saving Features: - Take advantage of the 7-day, 4-period-per-day programming schedules to optimize energy consumption and fit your lifestyle

Easy Control: - Use the Smart Life app, Alexa app, or Google Assistant to control your WiFi thermostat anytime, anywhere - 6.8 sq. inch backlit digital display and intuitive controls provide a user-friendly experience - Designed for reliable performance and precise temperature control

Wiring Considerations: - If you don't have a dedicated C-wire, check if you have an unused wire that can serve as the C-wire - As an alternative, you can use the G-wire as the C-wire for gas/propane furnaces and heat pumps without auxiliary heat (this solution does not work for oil furnaces)

Cautions: - Carefully check system compatibility before purchasing - Read the installation manual and wiring diagrams thoroughly before installing - Incorrect wiring may damage the thermostat - If the thermostat doesn't power on after installation, check compatibility or consider hiring an HVAC technician for assistance

Note: - The backlight will automatically turn off after 30 seconds of inactivity, but pressing any key will illuminate it again - The system clock will automatically synchronize with your smartphone when the WiFi connection is successful.
