Questions buyers ask
Questions buyers ask
Is this everything I need?
Yes, for a ducted RV with lateral roof ducts: heat pump, heat pump ChillGrille with its control box, WiFi wall thermostat, gasket. Your existing 12 V thermostat wire usually reaches the new stat.
Do I need the 9530A751 control package?
No. Coleman-Mach's 2025 catalog pairs the 8630A635 with a wall thermostat only; the heat pump control box is built in.
How cold can it heat?
A heat pump moves heat in from outside, so it works best in mild weather and shuts off near freezing. Keep the furnace for cold nights; the heat pump saves propane on cool mornings and shoulder-season evenings.
Will it run on my generator?
Plan on 3,500 W or more, as for any 15,000 BTU rooftop unit. Coleman-Mach does not publish a starting current for the heat pump models, so we do not promise a small-inverter start. Ask us before you rely on a 2,200 W generator.
Does the WiFi thermostat work without WiFi?
Yes, as a normal digital thermostat on the wall. The app needs a 2.4 GHz network.
