Hi,

This is how my technician wired my thermostat for heating and cooling:

My technician used a short strip of white wire to wire from white leg to yellow leg.
The white wire is not from the wall but he just stripped a piece to have enough
To wire from white leg to yellow leg.

The other color wire from the wall is connected to its leg color with
The exception no blue wire

The yellow wire from the wall is connected to the yellow
Leg.

Yellow leg has yellow wire and white wire.

Is it OK to wire like that?

Thanks,
Megan

I`m so confused!, if it is working that's what counts,, can`t hurt much,, it either works or doesn`t,, that's the cool thing about low voltage controls

Do you have a heat pump? Depending on the thermostat and the way it is configured, it might be OK. Some tstat applications have interesting hookup methods. Paraphrasing wmproop, if it ain't broke, don't fix it.

My a/c and heat is not fixed yet. Just wondering if it is OK.

It's a heat pump. My thermostat has no brand on it. My a/c and heat is not fixed yet.
I don't know anything about the unit at all. My technician wired something outside and
All of a sudden there was smoke coming out of all my vents. That's why I feel it is
Necessary to ask this question. I want to know what is going on for sure if it will work or not.

Y to W typically occurs in homes where the heat/cool mode is selected at the furnace and not the stat. In general they are not jumped. This would usually cause heat and cool to be on at the same time.

R, Rc and/or Rh are usually jumped.

Would it cause any damage in the long run?

Is your furnace in a mobile home?

Yes

If the system works now there's probably is no damage. Mobile home wiring can be confusing when the unit is switched at the furnace. It is a lod style two wire system.

Thank you everyone who respond.

My technician delayed another day and still the a/c and heat are not fixed.
So basically I'm just waiting right now.
