Need help with Trane TED330. Before Reliatel boards, uses the UCP board and a UVM board. Cooling setpoint is 50° Return air and outside air sensors are good. I do have a bad static pressure transducer but pulling the hoses off made that alarm go away for now. Between LVT 6 and 7 and 6 and 8 show off System status shows ok, 32vdc. I think that LVT 6 and 9. 6 and 10 has 1.5vdc so no service light is on. This thing should be coming on for cool. I’m at a loss at this point 🤷 For now I bypassed the board with a thermostat running through the safeties.
