Coleman-Mach Cool Only Analog RV Thermostat 12V
Coleman-Mach Cool Only Analog RV Thermostat 12V — Product description
This is the Coleman-Mach cool-only wall thermostat, the simple analog control for your RV's rooftop air conditioner. No screens, no menus, just a dial you set and forget. It runs on 12-volt DC, comes in black to match most modern interiors, and handles cooling duty without the complexity of a heat-pump or furnace-integrated unit.
If your RV's air conditioner just needs a straightforward way to call for cooling, this is it. The Coleman-Mach 7330-3861 is an analog wall thermostat built for one job, cooling, and it does that job without asking you to learn a menu system. You get a temperature dial and a fan control, both mechanical, both easy to read at a glance. Set it where you want it and let the AC do the rest.
We like recommending a simple analog thermostat like this for a few reasons. First, there's nothing to fail in software. No firmware, no pairing, no batteries dying at the worst moment. It draws its power from the RV's 12-volt DC system, so it wakes up the moment your coach does. Second, it's honest about what it is. This is a cool-only control. It won't run a furnace and it won't drive a heat pump. If your rig only has rooftop cooling, that's exactly what you want, and you're not paying for functions you'll never touch.
The black finish blends into most modern RV interiors better than the old bone-white units, and the low-profile face sits flat against the wall. Installation is familiar territory for anyone who's swapped a thermostat before. You're working with low-voltage DC wiring, so it's a manageable job with the power off and a little patience matching the leads.
Who's this for? Owners running a single-zone, cool-only Coleman-Mach rooftop system who want a reliable manual control, or anyone replacing a cracked or failed analog thermostat and who'd rather keep things simple. It's also a solid choice if you've had trouble with a digital unit and just want to go back to a dial that works.
A couple of honest notes. If your system uses a heat pump or a gas furnace, this isn't the control for it, and you'll want a heat-capable thermostat instead. And because it's analog, you won't get programmable schedules or a digital temperature readout. That's the trade. What you get in return is dead-simple operation that just about anyone in the family can use without a tutorial.

It's analog. You get a manual temperature dial and fan control rather than a digital screen. No programming, no menus, just set it and go.
What color is it?
Black. The finish sits flat against the wall and blends into most modern RV interiors.
