Thermostat Upgrade Kits
You do not need a new air conditioner to get a modern control. These kits pair a Coleman-Mach thermostat with the control box or ceiling assembly it requires, so the parts are compatible by construction: WiFi wall thermostat with its control box, digital zone thermostat with its zone control box, or the Bluetooth ceiling assembly that replaces the knob unit outright. Note that 9 Series controls do not work with 8 Series boxes; the kits handle that for you.
