Smart Thermostat with Alexa and Google Assistant Compatibility, 7 Day Programmable WiFi Control for Single Stage 1 Heat/1 Cool HVAC System

Experience effortless control of your home's temperature from anywhere with the MechDoc smart WIFI thermostat. Our goal is to bring you convenience for your daily life. Our thermostat is compatible with a wide range of systems and offers numerous features and specifications.

With compatibility for 85% of systems, our thermostat works with single stage 1 heat and 1 cool HVAC systems including gas or oil heat, electric furnaces, heat pump without aux heat, and cool/heat only systems such as floor or wall furnaces. Please refer to the #4 main image for wiring diagrams before making a purchase. Our thermostat supports conventional systems and heat pump systems with no more than 6 wires including RC, RH, C, G, W/O/B, and Y. When disconnecting wires, take a photo of the wire connections for future reference and use sticky tags to label each wire.

It is important to note that our thermostat requires a 24VAC power supply and a C-wire for primary power. Battery power is not supported. Without a C-wire, our thermostat will not power up and cannot be used in your system. Please check if your home has a C-wire installed or if it needs a C-wire power adapter (sold separately).

Our thermostat offers smart home integration and works with voice assistant devices like Amazon Alexa and Google Assistant. It also features easy programming with flexible 7-day schedules and 4 periods per day, allowing you to optimize energy consumption. Control your Wi-Fi thermostat anytime, anywhere using the Smart Life app, Alexa app, or Google Assistant. Please note that our thermostat only supports 2.4 GHz Wi-Fi and not 5 GHz Wi-Fi.

Designed for easy operation, our thermostat features a large backlit digital display and user-friendly controls. It provides reliable performance and precise temperature control for long-lasting use.

If you don't have a C-wire, you can find an extra wire to act as a C-wire or use the G wire as a substitute for furnace systems that burn gas or propane (not compatible with oil burners) and heat pumps without backup heat. Detailed instructions are provided for both scenarios in the installation manual.

Please exercise caution and carefully check system compatibility and wiring diagrams before purchasing and installing the thermostat. Incorrect wiring can damage the thermostat. If you encounter any issues during installation, please consult a local HVAC technician.

Note that the LCD backlight automatically turns off after 30 seconds of inactivity. Pressing any key will illuminate the backlight again. The thermostat's system clock synchronizes automatically with your cellphone when successfully connected to Wi-Fi.
