My ac is working and the digital display and backlight is on but when I press the up and down arrows the temperature will not change it is staying on 78. I tried changing the battery and still have the problem. Central air conditioning in Florida.
I am replacing the old Honeywell TH4110D and the wires connected are
Y Yellow and white
O no wire
R red with the Rc and R has jumper in
B and C no wire
Have bought a new Honeywell RTH6350D 5.2 day
These wires show a Y2, W2, G, W, Y, R and Rc
My question now is should I put wires the same as old with a yellow and white on the yellow or put one white on the W2.
