We have a new double wide and I want to replace the thermostat with a new programmable one. We took off the old one and it has 3 red wires, 2 yellow, 1 white and 1 green. I get the 2 red indicate a multi system hvac, but what about the extra red one and the extra yellow one. Where do those go in the wiring of the new system?

  • Where were they hooked up on the old thermostat? And good job mentioning mobile home because a lot of things in them is non-standard. – JPhi1618 Mar 30 '16 at 20:40
