Fairly close!

 

When I set the temp to 76 on either the unit, wall stat, or remote it will cool to 72 or 73, the condenser will shut off and will not come back on until the temp gets up to 79 or 80. These 6 to 8-degree temp swings are brutal. This just doesn't seem right and very uncomfortable. This is a Cooper & Hunter unit and their tech support is telling me that is how it should work. The other mini splits I owned in the past years held the temperature pretty close. The board and thermisters have been replaced in the cassette and thermisters in the condenser. Is it possible that the board in the condenser has issues or possibly an electrical surge or lightning?

 

Oversized?

 

Where are you neasuring this temp?

What brand mini split?

I find most mini splits overshot at least 3-4 degrees.

 

Measuring temp with the wired wall thermostat and with the remote with each one in the "Follow Me" mode when in use.

This is a Cooper and Hunter cassette unit.

The unit was installed by a licensed HVAC tech and I have had two other techs trying to solve this issue.

 

I doubt anybody here will have a solution for a cooper and hunter brand mini split. Once you go outside of top-tier mini splits its a sh*t show.

 

I purchased the size recommended by Cooper & Hunter. It is an 18,000 BTU cassette located in approximately 650 sq ft of living room and kitchen in South Louisiana.

 

Have you tried their tech support?
