After installing the wet switch and turning power back on we discovered the unit running the fan. After two hours checking wiring and diagnostic work and confirming with tech support we have determined the control board is defective. The outdoor Y terminal disconnected will allow the system to run normal in heating mode but removes cooling entirely. Returned to complete the control board installation. Issues were all addressed, tested wet switch, tested drains with water bottles. No issues are present. Thank you for choosing CPI Plumbing and Heating Inc.
