It runs on 12 volt DC, gives you a clear digital readout, high\/low fan speeds, and an Auto\/On fan mode in a low-profile black case.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Coleman 9420A381 is a single-stage digital wall thermostat built for Coleman Mach heat pump and gas furnace RV systems. If your old dial control finally gave up, or you just want a clean digital readout at the wall, this is the direct replacement for a Coleman Mach heat pump setup. It runs on 12 volt DC, so it wires straight into your RV's house electrical without any extra transformer.\u003c\/p\u003e\n\u003cp\u003eWhat you get is straightforward, honest climate control. The digital readout shows you exactly where the temperature sits, no squinting at a dial. You get high and low fan speed control, so you can run it quiet overnight and step it up when the coach heats up midday. The fan mode switches between Auto and On. Leave it on Auto and the fan cycles with the system. Flip it to On and the fan runs continuously to keep air moving, which a lot of folks prefer for even temps front to back.\u003c\/p\u003e\n\u003cp\u003eThis is a single-stage control, meaning it manages one stage of heating and cooling. It's designed specifically for Coleman Mach heat pump systems, and it also handles gas furnace control in those setups. That's an important point. This isn't a universal thermostat you drop on any RV. It talks to Coleman Mach heat pump gear, so check that your rooftop unit and control box match before you order.\u003c\/p\u003e\n\u003cp\u003eInstallation is about as simple as it gets. The unit comes pre-wired to two electrical connectors, so you're plugging into existing harnesses instead of fishing individual leads onto screw terminals. That keeps the swap quick even if wiring isn't your favorite job. The black case measures 5-1\/2 inches long by 3-3\/4 inches wide by 1-1\/8 inches deep, a low-profile footprint that sits flat against the wall without dominating the space.\u003c\/p\u003e\n\u003cp\u003eIf you're a full-timer or a weekend camper who wants dependable, no-nonsense temperature control that matches your Coleman Mach system, this is the replacement to grab. Wire it in, set your temp, and get back to enjoying the trip.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eSingle-stage digital control for Coleman Mach heat pump and gas furnace systems, one unit for both heating and cooling\u003c\/li\u003e\n  \u003cli\u003eDigital temperature readout, no more guessing at a dial position\u003c\/li\u003e\n  \u003cli\u003eHigh and low fan speed control for quiet nights and strong midday cooling\u003c\/li\u003e\n  \u003cli\u003eAuto\/On fan mode, cycle the fan with the system or run continuous airflow\u003c\/li\u003e\n  \u003cli\u003e12 volt DC operation wires directly into RV house power, no separate transformer\u003c\/li\u003e\n  \u003cli\u003ePre-wired to 2 electrical connectors for plug-in installation\u003c\/li\u003e\n  \u003cli\u003eBlack case, 5-1\/2 in L x 3-3\/4 in W x 1-1\/8 in H low-profile footprint\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Coleman reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWill this thermostat work with any RV air conditioner?\u003c\/summary\u003e\n    \u003cp\u003eNo. The 9420A381 is designed for Coleman Mach heat pump systems only.
