Hi all- Late last year, I had a $500 electric bill that I discovered was caused by my system running on backup heat for weeks. The compressor wouldn't start due to a high pressure fault. A technician came out and got it working again, though at the time, I didn't understand exactly how. He said he disabled something that was "really only needed for commercial installs". Fast forward to today, I'm looking at the board to verify the wiring so I can install a smart thermostat. I see that he took the loop pressure switches out of the circuit and shorted the connections. And I also see the label on the switches warning explicitly to NOT do this. Is this bad, and do I need to get it fixed? Thanks in advance for any help.
