The Old Thermostat
Step 1: Check system
Before getting started, make sure that your HVAC system works normally.
Do not short across electric terminals at the control on the furnace or air conditioner to test the system. This may damage the
thermostat.
Step 2: Switch off power
Switch off the power to your heating and cooling systems at the breaker box or the system switch.

Step 4: Label all wires.
Use the supplied sticky tags to label each wire. Label wires according to old thermostat terminal designations and make sure that the
wires are labeled correctly.
If no tag matches a terminal designation, write the appropriate letter on a blank sticky tag.

Prepare Wires
８
Follow the tips for security:
1. Make sure that the diameter of wire is 18-24AWG;
2. Make sure that the length of exposed wire is 1/8 of the whole wire.
CAUTION: Make sure your system voltage is 24V AC. If the old thermostat is labeled 120V or 240V, or has thick wires with wire nuts, your
system is high voltage. Then do not install the Smart Thermostat, and contact HVAC specialist.

Install the Smart Thermostat
Step 1: Remove the anti-loosening screws at the bottom of the Smart Thermostat and take down its base.
After Separation:

Step 2: Mount decorative plate (Optional).
Mount the optional decorative plate to cover holes or marks made by the old thermostat. Attach the base and decorative plate together
to the wall.

Step 3: Wire the Smart Thermostat.
It is best to have this operation done by a HVAC specialist and there is a risk if it is done by a non-technical person.
Connect wires to the Smart Thermostat and mark the connected wires with a pencil in the image below. This information will be needed
when you configure the Smart Thermostat.
• Please make sure your system has a C-wire and connect it to the Terminal C on the Smart Thermostat. If your system does not have a
C-wire, it’s better to contact a specialist.
• Without C-wire, the battery of thermostat that has network function will be running out quickly.
