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 have a Rheem Gas Furnace with an old analog thermostat (Wires conneected to terminals R and 4 for the thermostat). I went to install a Rheem digital and programmable thermostat and it indicated that it would not work for that wire configuration (Instructions indicated that the thermostat would not work with wires to the #4 thermostat terminal). Is there a setting on the furnace circuit board I can change, or is there a digital, programmable thermostat one can use on this unit - Model RGDJ 12EARJR?


if you have 2 wire at thermostat Terminals at furnace that the thermostat wire attach to should be R & W if your new thermostat has R & W terminals is should work, an easy thing to remember is the red wire on R the white wire on W. If 4 wire at thermostat at furnace green on G, Blue on Y, red on R,and white on W same at thermostat If these do not match find a thermostat with these terminals

problem wiring new thermostat


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)
