Hope someone can help with this! I have a Coleman 3400A816 unit with a Carrier 38yg outside unit. There are 4 wires coming out of the coleman / aspen unit to connect to a thermostat, They are yellow,green,red and brown. red and yellow both go to the transformer. how do I connect the thermostat. Someone else disconnected all the wires.
