I am working with a Trane Rtu M/N YCH150C4LOAB..S/N L06104. Customer wants to replace the zone sensor with a programmable thermostat.The existing sensor is a BAYSEN008B. I have no wiring diagram so I am not sure how to connect a 24 v thermostat and if its even possible. The sensor wires are wired to terminals 1 2 3 4 5
Any insight would be appreciated.
