Didn't open the box & had to send it to the garage for the install , I think you are right & will confirm it when i go to the garage.

The comp solenoid allows you to run the AC system in 2 modes:
1. Cabin and Chiller
2. Chiller only (race track safe)
In chiller only mode you are able to get colder intake temps and you will pass tech inspection at your race track as condensation is then unable to form on the cabin evaporator and you are then allowed to use the AC system on the track, as long as your intercooler lines are also insulated to not drip condensation.
The solenoid is controlled by a simple ON/OFF switch inside the cabin.

What you are talking about is the competition & street mode .
