Analog to Digital RV Thermostat Upgrade Mod *Explained*

I swap out my OEM Coleman Mach manual slider type thermostat for a battery-operated Honeywell RTH5100B digital with auto heat and cooling changeover.

I've done this particular upgrade a few times in the past. First I upgraded to a Hunter 42999B and then to a Honeywell Focus Pro 5000 series.

Honeywell FocusPro 5000 - https://www.loveyourrv.com/rv-thermostat-upgrade-honeywell-focuspro-5000/

The Hunter worked well but didn't have the auto heating to cooling switchover capability, so I changed it to the Focuspro 5000. Unfortunately, the Focus Pro 5000 failed, and I had to in a pinch put the old analog thermostat back in place.

Recently I bought a replacement Honeywell digital, so I decided to video the installation in greater detail than before. I answer some of the questions I've received about the mod and explain operation and wiring.

I've found some confusion has come when RVers try and follow my Coleman Mach wiring when replacing a Dometic Duo Therm. The two companies use slightly different wiring methods. The Honeywell will still work but needs a different hookup. Here is a link to a forum post with photos and a wiring diagram for the Duo Therm upgrade - https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/28254233.cfm
