HOW TO BUY/ & INSTALL THERMOSTATS
SAVE ENERGY COSTS:
Your home's thermostat is probably the most important part of your
HVAC comfort system. If your home has an outdated thermostat, you may
be wasting your energy dollars. As a rule of thumb, every degree you
turn down your thermostat will save you 3% of energy costs over a 24
-hour period. Likewise for every degree the old thermostat is off,
you will pay 3% extra on your Utility bill.
Do you ever wish that someone else would get up and turn the heat on
in the morning? Do you ever wake up late at night and realize that
you forgot to turn the heat down? Are you looking for a quality
thermostat for a heat pump? Don't you wish that you could set and
forget your thermostat? Are the numbers on your thermostat worn down
or just too tiny to read? Is that thermostat on the wall older than
If your answer to any or all of these questions is YES, It's time to
replace that old thermostat. You may want to consider a Programmable
thermostat. Programmable thermostats can minimize wasted energy.
Sometimes by as much as 15% of your utility bill.
SHOULD YOU MOVE YOUR THERMOSTAT?
Sometimes it may be necessary to move your thermostat. Thermostats
should be mounted away from sources of heat, cold, and drafts. For
* They should be mounted on inside walls,
* Away from AC vents or returns,
* Away from stoves or other sources of heat,
* Centrally situated (not on the far side of the house),
* Out of direct sunlight.
If a thermostat is 2 = degrees warmer because of a heat source you
will pay an extra 10% on your utility bill. Likewise if it is on an
outside wall on a cold day and reads 2 = degrees cooler you will pay
10% more.If you decide to move it you may want to consider a wireless
thermostat. It is expensive ($200) but if you have to spend the same
amount (or more) to move it you lose nothing and gain all the
convenience of a movable one. Besides, you can take it with you if
It will cost $150 to $250 for an AC Company technician to crawl
through your attic and move it. You can move the thermostat from room
to room at will and you can also have more than one in any room you
want (although only one can be active at a time). Wireless
thermostats are available through RCI Automation, LLC and other
Companies or call your local AC Company.
DO IT YOURSELF?
If you wish to replace it yourself you need to be warned of an
ELECTRICAL SHOCK HAZARD. Turn off power at the main service
panel by removing the fuse or switching the appropriate circuit
breaker to the off position before removing or installing any
thermostat.Installing a thermostat is a simple do-it-yourself home
improvement that can be done in about 30 minutes. Wireless are even
Before you start disconnecting the wires you should become familiar
with the colors and labels on the thermostat. Most newer thermostats
have a connector that has various letters on it. They are R, C, Y,
W1, W2, G, O, and B. Some thermostats do not have all the above
letters but they have most. The older "mercury switch" thermostats do
not have a connecter but rather small screw contacts but have no
fear, they are labeled by letters also. This depends on various
factors such as with Heat Pumps, one or two stage compressors, etc.
* (R), Red, hot side of transformer (24 volts AC). Be careful!
Although this is not high voltage it will still give you a shock.
* (C) Common side of transformer (usually Blue). York and Trane like
to use (B) as common. Brown common in York or Trane.
* (Y), Yellow, Compressor activity (cooling or cooling and heating on
a heat pump).
* (W), White, Heat (gas burner, oil burner, electric heat,
(auxiliary heat on a heat pump including defrost output from the
outdoor unit to activate electric heat and turn on the AUX. heat
* (G), Green, furnace/air handler blower fan. (Needed for air
conditioning, heat pumps and some electric furnaces).
* (O), Orange, Energize to cool (used for reversing valve on heat
* (B), Blue or Orange, Energize to heat (used on some systems,
Rheem/Ruud is notorious for this). Follow the steps below and
remember to check the owner's manual before installation:
1. Turn off power and remove the old thermostat.
2. Label wires if there is a difference in the color codes above,
attach thermostat mounting plate to wall and connect wires to
3. Snap thermostat onto mounting plate. (Make sure batteries are
installed if necessary.)
4. Program new unit (if applicable)
5. Turn all settings to off (including fan)
6. Turn on power.
