The control center for your heat pump is the thermostat installed on an interior wall of your home. There are many different types of thermostats, but they all operate pretty much the same. They have switches to select some or all of the following functions:
SETPOINT LEVER -A lever, usually near the top or bottom of the thermostat, is used to set the temperature you desire. The temperature you choose is called the “Setpoint.” (Some thermostats have two setpoint levers, one for heating and one for cooling.)
COOL -Turns cooling on when the temperature rises above setpoint.
HEAT -Turns your heating system on when temperature drops below setpoint.
AUTO -Turns on cooling or heating as required to maintain setpoints. Most thermostats have at least 4° separation between heating and cooling
OFF -Turns heating and Cooling modes off (The fan continues to run, especially in the FAN-ON mode.)
FAN-ON -Turns on fan for continuous operation.
FAN-AUTO -Fan cycles on and off with cooling or heating operations.
For the most economical operation of your system, select the highest summer setting and the lowest winter setting at which you are comfortable. Typical setpoints are 78° on cooling and 70° on heating. Remember, your operating cost goes up by 3% to 8% for each degree lower setting in summer and for each degree higher setting in winter depending on the type of heating system.
Night setback thermostats are available to automatically turn the temperature down at night and back up in the morning.
(Ask us for advice before installing a setback or “energy saving” thermostat.)
Here are some ways you can save electricity and improve your systems’ performance:
- Keep all grilles and registers open and clear of obstructions such as drapes or furniture.
- Keep doors and windows closed.
- Be sure all air ducts are well insulated and sealed with a vapor barrier.
- Let the sun in during the winter. Keep it out during the summer.
- Be sure clothes dryers are vented to the outside (away from your outdoor condenser unit).
- Fireplaces are pleasant, but most of them draw in more cold outside air than they heat. A fireplace may cause your system to run more.
- Use kitchen and bathroom exhaust fans only when necessary.
- Add insulation, storm windows and insulated outside doors. Seal cracks to prevent air leaks.
- Keep your system’s filters clean.
- Operating your indoor fan on AUTO costs less.
- Keep lamps, television and other heat sources away from thermostat.
- Keep power on at the outdoor unit at all times.
- Never use your condenser as a stand for garden hoses or tools.
- Use caution with lawn mower and trimmer to avoid damaging refrigerant piping or electrical wiring.
