Findings & Work Performed
What Tim documented during the visit
Thermostat not receiving common (running on batteries), Y1 and Y2 were jumpered causing constant second-stage operation; rooftop splitter and jack unsealed allowing supply/return air to mix.
Cleaned up and rewired thermostat and system wiring; separated Y1 and Y2 onto their own circuits; moved common from blue to unused orange wire so thermostat powered by system; sealed rooftop splitter elbow and inside roof jack to stop air mixing.
The Verification
Verification performed
Thermostat powered on without batteries; noted system should be cooling properly after sealing.
