How to Install a Programmable Thermostat
Programmable thermostats are a great way to save money and conserve energy. Two things we're all concerned about these days. Depending on the model you select, you can program day and night temperatures and even a setting for every day of the week. You'll be more comfortable with your heating and cooling bill too. Read the instructions with the new unit BEFORE starting the installation. Manufacturer's installation instructions might differ slightly for each model. Here are the basic steps.

Instructions:
- Turn off the power supply to the thermostat. Remove the old thermostat, including the wall plate.
Your thermostat will have two or four wires depending on whether your heating and cooling systems are separate or one unit. Label the wires, noting where they were attached on the old thermostat. Secure them (tie into a loop or tape them to the wall) to keep them from falling back into the wall. - Install the new wall plate, if there is one. You may need to drill new holes for the new model. Use a level to mark where the holes are to be drilled. Use drywall anchors, if necessary.
Connect the wires as directed by the instructions that come with your particular unit. Follow these instructions carefully. Install batteries, if needed.- Mount the unit to the wallplate. Restore power and program the new thermostat as directed. If you come home at 5pm, make sure your heat kicks back on around 4:30pm so it's nice and toasty when you walk in the door. And breath easy that you didn't keep an empty home warm and cozy while you were away.
