I have a customer that bought a Trane heat pump and had it installed by "Billy-Joe-Jim-Bob". I am not a Trane guy, so I don't understand all I know about them. I have it working with one exception... Here's the info then the question.
XL1400 heat pump TWY036A100A3 N206RA81F The control wires were not connected correctly, and I have the basics correct for 24v, contactor, common, and RV, The problem lies with 3 wires...... brown, black, and red w/white stripe.
Here's the question....
Which one of those 3 wires energize the air handler heat strips so it doesn't blow snowballs in defrost??
The books and paperwork that the owner has are not real specific. Any help please??
Thanx
