Honeywell RTH7600 Thermostat Installaton w/Trane XE1000
Here's what I have:
Trane XE1000 Heat Pump
Trane TWE060C5FC1 Air Handler
???? WTS0702(F) Heat Unit
Trane Thermostat (Weathertron - BAYSTAT240)
I am installing a Honeywell RTH7600 TouchScreen Thermostat
Closely following the manual and some tips online here is how I have wired the RTH7600:
Note: The layout is BAYSTAT240 - WIRE - RTH7600
(The forum doesn't keep my formatting unfortunately)
So the system seemed to be running fine and behaving ok except the other day I noticed that the outside compressor is running ALL the time. And it did not do this until I installed the new thermostat. So what could be wrong with how I wired the thermostat?

Ok, here it is:

Everything is wired up correct.
Make sure the Y wire is not touching R.
If it still running, undo the Y wire and see if that stops the unit outside.
Also, Do you know what your KW rating on the air handler? Reason I asked is you don't have E wired up.

Ok, I thought I had the wiring right. I'm wondering if the contactor is maybe acting up. It's 14 years old and original. I've replaced all the caps last year but thought the contactor was still ok. Maybe not.
Anyway, the air handler is rated at 6A. And the heater unit is 7kw.
It's a multi-stage heat. Heat pump and emergency strips.

You have on bank of heat strip? If yes, then you need to add a jumper between Aux and E on the T-stat.
if you have more than one bank, then you need to add the unused t-stat wire to E and go to the air handler and wire E to W2 at the air handler.
