Lowering the max cycles per hour for the compressor on an electric heat pump

[Tubby]

Just wondering if anyone has experience with lowering the CPH so the compressor doesn't start up as often. The idea is to get better efficiency and less wear on the parts. How much of a difference will this make on the longevity of my system? That's the only reason I'm considering it. How much does it reduce comfort?

The range of CPH is 1 thru 6; currently is is set to 5 on my system. Grok says 3 is often the preferred choice.

Supposedly the thermostat (Honeywell) uses a fixed temperature differential (around ±1°F), so it will not overshoot the setpoint to run longer.

1° is a very tight band might want to see if that can be change to 1.5 to 2°. When changing any settings take baby steps. Don't change any more t han one setting at a time then give it at least few hours. Like to write everything down from where i started. Model of stat?

The manual states explicitly that you can't change the deadband amount. So, from what I gather, there will simply be times when the house gets a little chilly or muggy waiting for the system to kick in. With a lower CPH, supposedly run times will tend to increase as startups are fewer.

Yes, I always say: Make small adjustments.

Try #1 setting for the hp.
