It's the heat pump version of the Mach control family, so it switches both cooling and heating, and it ships as a complete kit with the control box and all the mounting hardware.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Coleman Mach 9630B752 is the 12 volt DC zone control kit that sits between your wall thermostat and your Coleman Mach rooftop heat pump. If your coach runs a heat pump up top and you want a single thermostat calling the shots for both cooling and heating, this is the box that makes that happen. It's the heat pump version of the Mach zone control family, so it's built to drive a reversing heat pump, not just a plain air conditioner.\u003c\/p\u003e\n\u003cp\u003eThink of the control box as the brain of the system. Your thermostat tells it what you want, and it decides when the compressor, the fan, and the reversing valve fire. Coleman built this one to pair with the 9330A3341 black thermostat or the 9330A3351 white thermostat. Those thermostats are sold separately, so pick the color that matches your interior and order it alongside this kit if you don't already have one on the wall. Without one of those heads on the wall, the control box has nothing to listen to.\u003c\/p\u003e\n\u003cp\u003eBecause it's the heat pump control, it handles both sides of the season. In summer it runs the compressor for cooling like any rooftop air conditioner. When the nights get cold, it reverses the refrigerant flow and pulls heat out of the outside air, so you get efficient warmth without leaning hard on your propane furnace. That's the whole point of a rooftop heat pump, and this control box is what actually manages the switch between the two modes.\u003c\/p\u003e\n\u003cp\u003eThe kit shows up with everything you need to wire the control box in cleanly. You get the control box itself, the sensor wire lead that reads coil temperature, the metal wire clips, a plastic Romex strain relief so your wiring doesn't chafe where it enters the box, a clamp, springs, and washers. It's the full hardware set, not just a bare board. That matters when you're up on a roof or reaching into a ceiling assembly and you don't want to be hunting around for a missing clip.\u003c\/p\u003e\n\u003cp\u003eMost folks reach for this kit for one of two reasons. Either the old control box has failed and the heat pump quit responding to the thermostat, or you're upgrading an older Mach system to run a modern zone thermostat. If your rooftop unit spins up but won't switch into heat, or the thermostat lights up but nothing happens on the roof, a dead control box is a common culprit. This is the part that brings it back to life.\u003c\/p\u003e\n\u003cp\u003eInstallation is a real job, but it's within reach for a handy owner. You'll be working at 12 volts, matching the wiring diagram that ships with the kit, and connecting the sensor lead to the coil. If you're comfortable pulling the ceiling assembly cover and reading a wiring diagram, you can handle it. If wiring makes you nervous, have an RV tech do it. Getting the sensor and the thermostat leads landed right is what keeps the system safe and accurate.\u003c\/p\u003e\n\u003cp\u003eOne thing to be clear on. This is the control box kit, not the thermostat and not the heat strips. It doesn't include the wall thermostat, and it isn't a full rooftop unit. It's the piece in the middle that lets a Coleman Mach heat pump and a Mach zone thermostat talk to each other. Match it to your existing Mach heat pump and you're set.\u003c\/p\u003e\n\u003cp\u003eCompatibility is the thing to nail down before you order. This control box is built for Coleman Mach heat pump systems that use the 9330A3341 or 9330A3351 zone thermostat. If your rig runs a different Mach control family, check your model before you buy so you match the right box to the right roof unit. When in doubt, give us a call with your rooftop model and we'll help you confirm the fit.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e12 volt DC operation runs off your RV house system, so you don't need shore power to control the unit\u003c\/li\u003e\n  \u003cli\u003ePurpose-built heat pump control switches the reversing valve for both cooling and heating\u003c\/li\u003e\n  \u003cli\u003ePairs with the Coleman Mach 9330A3341 black or 9330A3351 white zone thermostat, sold separately\u003c\/li\u003e\n  \u003cli\u003eComplete hardware kit: control box, coil sensor wire lead, metal wire clips, plastic Romex strain relief, clamp, springs, and washers\u003c\/li\u003e\n  \u003cli\u003eCoil sensor wire lead reads evaporator temperature to help protect the compressor\u003c\/li\u003e\n  \u003cli\u003eDrop-in replacement for a failed Coleman Mach heat pump control box\u003c\/li\u003e\n  \u003cli\u003eMatches the Coleman Mach zone control family for a clean thermostat-to-rooftop connection\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 does the 9630B752 kit actually do?\u003c\/summary\u003e\n    \u003cp\u003eIt's the control box that sits between your wall thermostat and a Coleman Mach rooftop heat pump.
