Last year I removed my furnace as it didn’t work and installed a diesel heater instead. I now find that my thermostat is blank and will not run air conditioner. Apparently there is a connection with the furnace that turns on the thermostat. There is a 6 pin plug that attaches to furnace it has only 4 pins used, White wire 12VDC which also is number 1 from left on thermostat. Nr 2 not connected on thermostat. 3 on thermostat is red wire +12VDC. 4 is black on thermostat Relay Com. 5 is green AC compressor also at plug to furnace. 6 AC hi fan blue and also at Plug to furnace. 7 is low fan Orange on thermostat. 8TH on thermostat black TH from furnace.
Any( bright sparks) that can tell me how to possible jumper or attach wires so as to power up thermostat.
thanks Frank.
