Does the Coleman-Mach WiFi Thermostat Reduce Temperature Swings?

Published 07/22/2026

Question:

Does the Comfortinch state reduce the amount the temperature swings between on and off cycles for the furnace and AC? I believe this is called hysteresis. Our current Coleman-Mach digital thermostat lets the temperature swing at least three full degrees between cycling on and off.

Hi Jim, that's a great question. Yes, the Coleman-Mach WiFi Thermostat part # CM46MR does give you more control over how often your furnace and air conditioner cycle by using a Cycles Per Hour (CPH) setting instead of a fixed temperature differential. Increasing the CPH tells the thermostat to check and react to temperature changes more frequently, which typically results in smaller temperature swings and a more consistent indoor temperature. In other words, it doesn't adjust hysteresis directly, but it accomplishes a very similar goal.

You can also improve temperature consistency by running the fan continuously on Low or High instead of Auto. That keeps the air moving throughout the RV, which helps prevent hot and cold spots that can make the temperature swings feel even bigger. The WiFi thermostat also lets you make adjustments through the app, making it much easier to fine tune the system to your liking.

Out of curiosity, when do those temperature swings happen the most?

Thanks for the very prompt response. I've noticed the large amount of hysteresis both heating and cooling. The regular thermostat lets you get just a bit cooler or warmer than it should before it starts a heating/cooling cycle. Then it runs just a bit too long resulting in being just a bit too warm/cool before cycling off. It's just a nit, really, but during less temperate weather it happens a lot throughout the day and becomes annoying. Thanks again. Jim

@Jim That makes perfect sense, and I know exactly what you mean. Those bigger temperature swings can get old. Based on what Coleman-Mach publishes, the WiFi thermostat's Cycles Per Hour setting is intended to help the system react more frequently, which should make the temperature feel more consistent than a thermostat that waits several degrees before cycling. I just don't want to promise a specific temperature swing since Coleman-Mach doesn't publish that specification. If you end up making the switch, I'd love to hear how it compares to your current thermostat.
