thermostat installation

Attic fans - either roof-top or gable-end attic fans - can be electric or solar powered, and may allow huge energy savings. If your attic attains high temperatures in hot weather conditions and you want to lower these temperatures in order to get lower temperatures in your house, gable and roof-top attic fans are an alternative to consider.

Location

Thermostats should be located away from drafts and from heating or cooling sources. So, do not locate them near windows or doorways, and do not expose them to bright lamps and direct sunlight... Also do not block them with furniture or curtains. Programmable thermostats are often located in the hall, landing areas, stairs or other areas where they can detect temperatures.

Thermostats, replacements & Do-It-Yourself

Programmable thermostats involve a low voltage wiring installation, which makes the installation a relatively simple and safe job if there is already an existing wiring and an old thermostat. The previous attachments will help you to connect the new thermostat.

Just be careful, and do not forget obvious things like to shut down the electricity.

Read all the manufacturer’s instructions thoroughly. You will have to deal with some wires (usually 2–10 wires), but with the guiding instructions and the previous attachment points, the installation will be relatively easy.

Replacement steps

Follow some basic rules:

- Find out the existing wiring connections to your heating and cooling system.
- Match up the new wires with the old ones.
- Disconnect all the existing wiring, without losing or tangling the existing wiring.
- Drill the holes into the wall for the new thermostat.
- Connect the wires taking into account the spaces designed for them on the new thermostat subbase, that is, the back of the thermostat, which should be mounted first.
- With the wires properly connected, screw in the subbase.
- Connect the wires, paying close attention to the proper terminals; get stuck to the manual, the instructions and the labels.
- attach the thermostat to their base.

New installations

If the installation requires more than just a replacement, it’s better to call a professional. A proper installation and a good operation of your heating and cooling system are more important than some small savings.

Old thermostats with mercury switch

If you're replacing an old thermostat with a mercury switch, be careful not to break the tube with the mercury and look for advice on proper disposal.
