Hello,

I had a Trane XL14i 3.0 Ton Heat Pump Model 4TWX4036A and a Trane Variable Speed Air-Tite™ Convertible Air Handler Model 4TEE3F40A installed and a Trane Electronic Air Cleaner.

My questions is how do I enable the Comfort-R system? I see where dip switches 5 and 6 have to be in the "On" position in the Air Handler and I see in the wiring diagram that connectors "Y" and "O" should be jumpered together for Single Stage Cooling and 2 Stage Heat. However my system seems to wired like the Single Stage Heat Pump diagram. The Single Stage Heat Pump diagram makes no mention of jumpering "Y" and "O". I am not sure what the difference is between the 2 diagrams. I do not believe I have a huidistat and I am using a Honeywell CT3611 Programmable Thermostat which is basically like the Trane Model TAYSTAT500C.

Should I have gotten an XL15i instead?

Any help would be appreciated.

Thanks

Roy
