Thermostat Location

Install the thermostat approximately 4-5 feet (1.2 – 1.5m) above the floor in an area that has a good amount of air circulation and maintains an average room temperature.

Avoid installation in locations where the thermostat can be affected by drafts, dead air spots, hot or cold air ducts, sunlight, appliances, concealed pipes, chimneys, and outside walls.

Install your new TopTech thermostat in 5 basic steps:

1. Install the Sub-Base
2. Provide Power
3. Connect Your Wires
4. Set Installer Switches
5. Attach Thermostat to Sub-Base

Install the Sub-Base:

• Remove the sub-base from the body of the thermostat.
• Mount the sub-base as shown below:

Drill 3/16” pilot holes in your desired location. Use supplied anchors for drywall or plaster.

Provide Power

• For 24 Volt AC power, you must connect the common side of the transformer to the C terminal on the thermostat sub-base.
• For primary or back-up power, insert the 2 supplied “AA” type alkaline batteries into the battery compartment located on the front of the thermostat near the bottom. Make sure to position the Positive (+) and Negative (-) sides of the batteries correctly with the +/- symbols in the battery compartment.
