Comfort by Mitsubishi Electric

Now it never connects. And my old winter schedule is stuck somehow, so everyday its 80 degrees. Stinks!

Not sure what (if anything) I’m doing wrong, but the Comfort app keeps turning on my new (Mitsu Hyperheat) system pretty much every time it hits a new setting time, even when the temperature is perfectly between the limits set. For instance, at 8p (bedtime for us) every day, my summer schedule setting is heat-at-60F, cool-at-76. I took a screenshot the other night when it turned on at 8p: it said “currently” 69F (our windows were open and that was (roughly) the outdoor temp - very comfy sleeping temps for us). But the system went into cool mode, blowing cool air, yet showing a target temperature of 76. ?!? At first I thought I had reversed the cool and heat settings, but found I hadn’t - the app won’t let you set a cool-on temp target lower than your heat-on temp. Checking overall power usage when it does this, it steps up beyond that seen with just the fan on - so it sure looks like it’s actively trying to cool down our house when indoor temp is in the desired range and the windows are open. So now, most nights and sometimes during the day, I have to manually shut the system down or let the system run fruitlessly. I’ve deleted the schedule and redid it, and nothing changed/improved. I finally let the app update itself today to the “new, easier” scheduling, but I’m not holding my breath. And tech support for this app seems essentially nonexistent at Mitsubishi or the Mitsubishi Comfort app site , so I thought I’d try here.

Please update your temperature setpoint so there can be a better comfort control and efficient running of your system. Your auto dry temp adjustment screen is exactly what we need! You select a desired setpoint temp and be able to select 1-5deg up and down for comfort dead band. Many other brands have this option, not sure why this isn’t a simple add on option. Many people have moved away from Mitsubishi because of this.
