to many wires

I purchased a new thermostat and when I disconnected the old thermostat I seen 6 wires the new has places for 5. Out of the RV wall is 2 red wires and the 4 color coded wires. I can not find a thermostat with places for 6 wires, can anyone suggest what to do with this situation?

My first question is what are you controlling with that thermostat? A furnace, heat pump, air conditioner, or some combination? If a heat pump, does it have electric heat strips? Do you have more than one of any of those units? What are the brand names and model numbers? Did you check the manuals for the equipment you're trying to control to see if it has any special thermostat requirements? The installation manual should have wiring diagrams and show how things connect up.

As you can see, there are far too many possibilities, and many questions to be answered before a solution can be determined. Household furnaces and heat pumps are fairly standardized and thermostats are generally interchangeable. RV systems can run the whole range from simple to complicated, with some systems even requiring proprietary thermostats that can't be replaced with a simple household thermostat.

More information is needed.

The thermostat controls heat and a/c a/c is a Dometic duo-therm and not sure about the heater. The old thermostat has Heat /off/cool on one side Fan hi/low and below fan is ON/Auto top has the toggle for set temp.

This might help:
Hunter 4299B Digital Thermostat RV Installation
I used it a few years ago to replace the mechanical thermostat in my RV with a digital Hunter from Home Depot.

There is also some useful information here:
