York heat pump logs?

I have a York Affinity Series heat pump. I looked at the log by entering the service mode on the thermostat. I took some screen shots of the details of the logs. I have added the shots as attachments. Can anyone help me to understand these details & if I need to worry about any of them? There were 3 or 4 of the bottom one & 2 of the middle one. Thanks

It looks like you had a cooler than expected discharge line when running the unit back in December.
Probably not something to worry about in September.

A bonnet sensor is a leaving air sensor. It is used to lockout the gas furnace when the heat pump runs when the temperature in the duct gets too hot.

When switched off I would expect the furnace to get locked out from running at the same time as the heat pump, in heat mode.
If this is the case it would not be abnormal.
The installation manual could shine more light on the subject.

I would think that someone turned off power to service the unit or the power blinked July 23rd.
