It runs both the heat pump and gas furnace from one black panel, with a clear digital readout, high and low fan speeds, and Auto or On fan modes. Runs on 12 volt DC and ships with the plug connector for a clean wire-in.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Coleman Mach 9420A382 is the wall thermostat that runs the show in a Coleman Mach heat pump setup. It's a single-stage digital control built to manage both the heat pump and a gas furnace, so your coach moves between cooling, electric heat, and gas backup from one clean black panel. If your Coleman Mach heat pump system lost its thermostat or the display went dark, this is the direct replacement.\u003c\/p\u003e\n\u003cp\u003eHere's the important part. This control is made for Coleman Mach heat pump systems only. It isn't a universal thermostat you drop onto any rooftop unit. It talks to the Coleman Mach heat pump and gas furnace specifically, and that's what lets it hand heating duty over to the furnace when it's too cold outside for the heat pump to keep up. On a chilly morning in the mountains, that handoff is what keeps the coach warm without you touching a thing.\u003c\/p\u003e\n\u003cp\u003eThe digital readout makes setting temperature simple. No squinting at a dial. You get high and low fan speed control, so you can run the blower quiet overnight and turn it up when you want to heat or cool the coach fast. Fan mode switches between Auto and On. Auto cycles the fan with the system, and On runs it continuously to keep air moving and even out the hot and cold spots.\u003c\/p\u003e\n\u003cp\u003eIt runs on 12 volt DC, the standard for RV control circuits, and it ships with the plug connector so wiring in is straightforward. The black case measures 5-1\/2 inches long by 3-3\/4 inches wide by 1-1\/8 inches deep, a compact footprint that fits the typical Coleman Mach thermostat opening. Most folks comfortable with basic 12V work can swap this in an afternoon. One thing to confirm first: make sure your rooftop unit is actually a heat pump model. This control won't do the heat pump job on a cool-only air conditioner.\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 panel for cooling, electric heat, and gas backup\u003c\/li\u003e\n  \u003cli\u003eDigital readout for precise temperature setting, no analog dial guesswork\u003c\/li\u003e\n  \u003cli\u003eHigh and low fan speed control to run quiet overnight or move air fast\u003c\/li\u003e\n  \u003cli\u003eAuto and On fan mode, cycle the fan with the system or run it continuously for even airflow\u003c\/li\u003e\n  \u003cli\u003e12 volt DC operation, the standard RV rooftop control voltage\u003c\/li\u003e\n  \u003cli\u003eShips with the plug connector for a straightforward wire-in\u003c\/li\u003e\n  \u003cli\u003eCompact black case, 5-1\/2 in L x 3-3\/4 in W x 1-1\/8 in H, fits standard Coleman Mach openings\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\u003eWhat systems does the Coleman Mach 9420A382 thermostat work with?\u003c\/summary\u003e\n    \u003cp\u003eIt's built for Coleman Mach heat pump systems only.
