Smart Home Thermostat with Touchscreen for Alexa and Google Assistant

If you do not have the C-wire, you can try the following steps, but it is crucial to confirm with your HVAC manufacturer or an electric engineer first. For the furnace part, connect the G-wire to the C terminal and use a black jumper wire to connect the G and Y or W terminals (connect to W if you need heat, otherwise connect to Y). On the thermostat part, connect the G-wire to the C terminal on the wall plate, as the G terminal on the wall plate is blank.

A C-wire, also known as a common wire or a "continuous wire," is an electrical wire that provides a constant source of power to a thermostat or other HVAC equipment.

The Vine TJ560 WiFi Smart Thermostat and the TJ550 WiFi Smart Thermostat are two options for smart temperature control. The TJ560 has a 4-inch screen, while the TJ550 has a 2.8-inch screen. Both are touchscreen-operated, with the TJ560 having a touchscreen and the TJ550 having 3 touch buttons.

The Vine Smart Thermostats offer wide compatibility, working with 90% of HVAC systems, including conventional (2H/2C), heat pump (4H/2C), and various heat sources (natural gas, electric, hot water, gas fireplaces, oil). All system types require a common wire (C-wire) for proper operation.

Installation is quick and easy, with step-by-step online guides and videos to help users set up the thermostats in just 20 minutes or less. The Vine Thermostat App or Smart Life App allows remote control and monitoring of the WiFi-enabled thermostats. Additionally, voice control compatibility with Alexa and Google Home enables hands-free temperature adjustments.

The smart thermostats feature 7-day programmable schedules and an Auto Home/Away mode, automatically adjusting the room temperature to maintain comfort while helping to save on HVAC expenses. They are ENERGY STAR certified, ensuring energy efficiency.

Other practical functions include temperature alerts, filter change reminders, automatic time and date synchronization, and child lock functionality, all designed to provide comfort and peace of mind for homeowners.
