Your programmable thermostat should be installed on an interior wall, away from heating or cooling vents and other sources of heat or drafts (e.g., doorways, windows, skylights, direct sunlight, or bright lamps).
If you’re replacing an older programmable thermostat, be sure to read directions carefully and take the proper safety precautions. Programmable thermostats are a low-voltage wiring installation and involve anywhere from 2 to 10 wires, depending on your type of heating and cooling system. The electricity should be shut-off during any replacement.
The previous attachment points will reconnect your new unit. If the job requires more than just a replacement, call Jones Air Conditioning to ensure proper installation. It’s a good idea to upgrade an old manual thermostat to a programmable unit if you’re replacing a central air conditioning or heating system, given that programmable thermostats are far more accurate and will maximize the efficiency of your new system.
