The short cycling has been warm cycles each cycle gets that pre warmed compressor and condenser heat.
What bothers me is those last 4 or 5 degrees come on slower closer to the end of a 10 / 15 minute on cycle.
The short cycling issue has been fixed
Cause was it uses a internal thermostat to control its on/off cycles that was being cooled too quickly by the exhaust fan
Was leaving the fan on 24-7 this caused the vent to draw cool air over the ac's thermostat cooling it.
Before the ac duct the exhaust fan cycled the rooms air 24-7 without issue it helped to maintain a even temp between floors.
The fix was this Inkird 308 temp controller which arrived yesterday
One plug controls a heating circuit the other cooling
It allows me to turn off the fan after the AC shuts down , prevented it from cooling the AC's internal thermostat.
The temp probe is placed in free air above the Fan box where some of the AC's warm air hits it.
Can fine tune the start up delay by changing the relays cooling setting.
At a 75*setting the fan stays off for 15 minutes , at a 77* setting turning the fan off quicker it leaves the AC thermostat warmer allowing it to cycle on a 40 to 60 minute cycle.
It worked out well with last nights test the house was 19c this morning without short cycling.
