Questions 14-23 pertain to current Evolution Systems, do you understand Yes Question Title * 14. Communication wire from the air source to the outdoor unit uses A, B, and sometimes C A, B, C, D C, D B, D Question Title * 15. The manuals will tell you to wait 10 minutes after power down before handling the circuitry, why? You don't, the factory is just making rules Since AC voltage flows both ways on a wire, you have to wait for the opposite direction to flow out The AC voltage charges capacitors at a higher voltage than your meter reads at the incoming lugs. So the capacitors need time to drain Not all disconnects work correctly and powering down for 10 minutes will trip a breaker if something is wrong Question Title * 16. The PEV does what? Equalizes the pressures from the low and high sides Soft start the compressor Keep refrigerant pressures isolated from low to high sides Prevent the system from running when the pressures are equal Question Title * 17.
