Customer Question

I have red, blue, orange, green and black wire for thermostat. On the new Honey well thermostat I have C connection, G connection, Y connection, W connection,. Which colour wire connects to each connection? I know the black wire is the hot wire or R Connection. Please help as soon as possible.
The Totaline thermostat I removed, has the connection labels behind the wires and is white on white; very hard to see until you remove the thermostat and see it up close.
Also I turned off all breakers and thermostat remained live.

Answer:

It sounds like this thermostat may not work, based on the wiring you have listed that would be a heat pump unit and the connections on the thermostat do not support a heat pump so you may need a different thermostat to make this work.
