INSTALLING A NEW THERMOSTAT

WHEN BUYING A NEW THERMOSTAT THE WIRING MY SEEM CONFUSING MOST TIMES IF THE WIRES ARE PUT ON THE SAME TERMINALS AS OLD SUCH AS IF RED WENT TO TERM. R. IF YELLOW WENT TO Y. ETC. THE MOST COMMON CONFIGURATIONS ARE RED-POWER24VOLT-R
WHITE-W HEAT/ COMMON-C GREEN-FAN-G
YELLOW-COOLING-Y
PLACING THE WIRES ON THE NEW THERMOSTAT THE SAME AS OLD ONE WAS WIRED WILL WORK HOPE THIS IS HELPFUL TO HOMEOWNERS. A PROGRAMABLE THERMOSTAT CAN SAVE HUNDREDS EVERY YEAR.

I am replacing old 220 volt thermostat with a programable 220 volt thermostat. There are 6 wires in the box. (3 black & 3 red) There are only two black wires on the new thermostat. On the old thermostat two pairs of wires (2 red & 2 black) were wire to the two black wires on the thermostat. Another pair of wires (1 black & 1 red) were wired to the two red wires on the thermostat. How do I wire the new thermostat. Please Help! Confused!


Hi, this can be confusing. Be sure you have the power off before you wire it, but first you have to have an elect meter. The 6 wires in the box you will only use 2 of them. Cap the other 4 off. Use the 2 that have the correct voltage across them, 208, 220, 240 volts. The new stat is only set up for 2 hot wires 120 each. That will do it. Not to bad. be careful! Use care. Good Luck, Sincerely,

9 TIMES OUT OF 10 YOU PLACE THE COLORS ON THE TERMINALS MARKED W/ THE WIRE COLORS. BUT YOU SHOULD LABEL THE WIRES TO THE CORRESPONDING LETTERS ON THE OLD THERMASTAT THEN PLACE ON SAME LETTERS ON THE NEW. HOPE THIS HELPS EX. YELLOW (Y) RED (R)
