If you need more info let me know.

Thanks to anyone that can help in advance.

B-blue-C

*Remove the jumper at the air handler W2 and W1 if you have an extra wire tuck aside. Take the Extra Wire you have and put it on E at the T-stat, and W2 at the air handler.

If you don't have an extra wire, let me know.

Set up menu.

#1 to 5
3 to 1
5 to 3 (if shown)
6 to 9
8 to 3
9 to 3
26 to 1 (if you want to change, you can.. see note on page 14)

 

Ok- I don't have an extra wire at the inside unit. Just a U shape striped piece of copper going from W1 to W2.

On W1 I have the white wire coming from the thermostat and a white wire from the outside unit.

So let me know what I should do with the white wire and if I still need to remove the jumper since I don't have an extra wire.

Thanks again.

 

Are you able to pull a new set if wire?? It'll be better if you can, but if you can't, it's not the end of the world.

Leave the jumper in place at the air handler. Then at the t-stat put a jumper wire between E and Aux.

???? That shouldn't be there.. Please tell me what other wires you got coming in from outside, and where they are on the air handler.

 

white wire coming in from outside unit is for heat during defrost mode of heat pump. You need that.
Some units are set up to only bring on 1 heating element during the defrost so you can have a w1 and w2. Sounds like yours is set up to bring on all heat during defrost, 2nd stage and emergancy heat.

 

That's right, I wasn't thinking about that at the time.

That's why I am trying to see if you are able to pull another set of wire to help break the stages down as needed.. not all at once.

 

Jays right if you can pull new wire and are comfortable doing this you can set up your unit to not have all banks of heat to come on at once. You only need to add heat during defrost mode because the heat pump is running as an a/c.

If you can't, then leave the jumper wire be at the air handler, and add a jumper at the t-stat's Aux, and E.

 

I can pull an extra wire no trouble.

As for the wire coming from outside. I have Red-Blue-Brown-Yellow, all matching up the same as the ones coming from the thermostat-just no green wire coming from the outside.

If you think I need to remove the W1 to W2 jumper & pull an extra wire as well as move the white wire from the outside unit let me know.

I take it that W1-White-to Aux and the new wire I will run will go to W2-E on the new thermostat, right?

Thanks for all the help.

 

Great, You'll be happy that you did cuz you are not going to be using all your electric heat at once, will save some $$$ down the road. Buy the 18 gauge-7 wire t-stat wire.

You are good, don't change anything.

The white wire from outside stays on W1, when you do pull new wire, remove the jumper between W1, W2

Right.

 

I have everything hooked up and all the system test went well.

I have a question about the setup.

I have:

1-5 set- 2 heat/1 cool heat pump(with aux. heat)
3-1 not set- in book but option not offered
5-3 not set- in book but option not offered
6-9 set- stage 2 heat cycle- For electric furnaces
8-3 set- emergency heat cycle- For hot water systems & furnaces of over 90% efficiency
9-3 set- Stage 1 comp. cycle rate
26-1 set aux heat -economy


Is this setup correct?

Thanks again for all the help and I will enjoy the money saved by running the extra wire.

Look forward to hearing from you on the setup.

 

Yes, you should be good with the set up.

The reason I got #8 set to 3, is that 9 will be cycling on and off way too often, and may be annoying. How ever, if you feel that 3 is getting the place too warm, you can move it down to 5. but I've had other says they are happy with 3.

The 3 or 5 or 9 means Cycles per hour on an avg. Another word, is if you had it set to 9, the air handler is going to cycle on about 9 times an hour!

 

Thanks for all the help.

 

You're Welcome!
