Yes, emergency heat works with this setup. The installation manual may indicate what each terminal is controlling. Basically I have an older honeywell programmable thermostat with 7 wires attached. There is a white, black and grey wrapped up, not used. If the tech installed the base exactly level, the unit would read right it says here. Typically W1 and W2 are simply hooked together at the air handler, rarely is a 2 stage thermostat used to control each bank separately.

The problem is that once you have gotten your nifty new product, the trane model baystat 239 wiring diagram gets a brief glance, maybe a once over, but it often tends to get discarded or lost with the original packaging. Hope this helps and good luck! Content : These Thermostats And Subbases Provide Low Voltage Control Of Multistage Heating.
I couldn't find one at my local hardware store, so I provided the link to the one I got from Amazon. This will leave the Gateway in inclusion mode for 3 minutes to enable you to enroll the thermostat controls. Well, it's more like the X2 was extended to W as well. The black wire loop you see in the center hole is unconnected. The power shuts off and on and I programmed the unit the way I was supposed to I think.
