Arrived on site to address unit not shutting off. Customer is interested in having positive control over this system. The RTU in question is #2 and serves the back supply / service room (Trane 5Ton s/n: 154112655L) The ReliaTel dehumidification system keeps the fan and compressor running even though the thermostat was turned off. I went through all installer setup options in the Trane BAYSTAT152A thermostat, even resetting all settings to original settings and set the stat up. No changes released control fully to the thermostat until the remote humidity sensor was taken out of the circuit. One wire was cut and taped and left at the sensor in case the sensor is wanted at a later date. The system is now operating the way the customer wants, and is operating properly at this time.

The inducer was only getting one leg of power. I checked and tightened the connections now the inducer is getting both 120v legs of power. The unit is heating, I cycled the heat on numerous times with no issues. The mullinax plug is where the connection was lost. The unit is heating as designed at this time.
