Installing a Filtrete 3m22 from a Trane weathertron
I have a Trane Weathertron that I would like to replace with a Filtrete 3m22 but the wiring is a little confusing.
The wires I have are
Wires connected to
Black- X2
Orange- O
Green -G
Yellow-Y
Brown-T
Red- R
White-W
Blue-B
The options I have on the Filtrete are:
C,B,O,W,W2,Y,Y2,RH,RC,G,A
I was thinking the set-up on the new system should be:
Orange -O
Green-G
Yellow-Y
brown/Tan- tape off
Red -RH which is jumped to RC
White -W
Blue to C
Black/X2- ? I'm not sure about this one
Could you tell me if this is correct and where the Black/x2 should connect to?
Thanks Shad

white goes to w2. x2 per your instruction booklet gets taped off. I don't like this because this thermostat gives you no control of emergency heat if your HP ever has problems, you are stuck without heat.

It looks like you woud have to move jumper 8 to 6.
I'd return it and get a Honeywell.
"If you have a heat pump with auxiliary heat, and the heat pump is not
working properly, your thermostat will still keep your room temperature
within about 2F of the target temperature.
•To select Auxiliary ONLY heat by temporally moving the HEAT PUMP
[Jumper 8] jumper to the HP-AUX ONLY position [Jumper 6]. This will keep
your room temperature within the swing setting of the target temperature.
•Be sure to restore it to PUMP when the pump is again operational as aux
heat is more expensive than pump heat."

What about hooking up the X2 to W2 and the White to W ? Would that keep my Emergency heat hooked up? The Tstat has a Switch for Emergency heat inside the top cover. I didn't have an instruction book that came with it but did look on line but didn't see anything about the Emergency heat wire.

Filtrete 3m-22 thermostat installation manual
see page 15 : 5 Wire HEAT PUMP with Auxiliary Heat. W is not used.
See page 18 also for descriptions on X2.
This thermostat is very limited in functionality.

Ok thanks, You have helped a lot. I got it all installed and it is running like it is supposed too. I have never really needed the emergency heat but I will look into a Honeywell where I can use the emergency heat.

Emergency Heat
While reading the Operation Guide, it stated that an Emergency Switch (labeled EMER HEAT) is located under the upper cover which allows you to turn on emergency heat if the HP is no longer functioning. I checked and the switch is in fact there.
