Hi, i have recently purchased and tried to install a New Touchscreen Thermostat. I tried to follow and label and correctly wire the thermostat to my furnace and A/C but it seems i have not done it right. I can get the heat to work, but when i switch to AC, there is only regular coming out, like the compressor is not turned on or something. I tried to look at the terminals on the furnace and old thermostat.
This is the way it is was connected on the board on the furnace, 5 terminals, C which was connected to a white wire running to the AC, a G terminal connected to the G on the thermostat, a Y terminal connected to a red wire going to the AC and also a Y terminal on the thermostat,W connected to the W, and finally R connected to the RH on the thermostat. Also RH and RC are connected together on the thermostat. So i had only 4 wires from the furnace to the old thermostat.
I have about 12 terminals on the new thermostat: N,I1,I2,Dh,C,H,Y2,R,Ob,W2,G,Y1
This is what i did for the new thermostat. The C terminal on the furnace runs to the C on the thermostat and also a white wire to the AC unit. G to G. Y to Y1 on the thermostat and aslo the Red wire going to the AC. W to W2 and R to R. So i am using 5 wires now.
The thermostat is working so i obviously have power to it, when i switch to AC, the compressor doesnt kick in. Does anybody have any clue what i did wrong ????
Thanks and sorry this is so long.
