16 Seer Lennox unit

[superd77]

Yeah this is what the supervisor gave me was a one heat one cool thermostat on a 2 stage ac unit. I thought that was messed up. Why have the customer pay for a nice unit and not give them all the options the unit is capable of doing.

I have the G61MPV series furnace.

here is the wiring diagram that is in the furnace manual:

tstat control term. strip outdoor unit
w------W1
r-------R
g-------G
c-------C------------------c
Y2
y-------Y1-----------------y

That is how I have it wired up

The wiring diagram for the outside unit should be in the outdoor unit.....

Maybe your superviser needs to read the manual..

Three won't work, Dude!!! It will never go into high speed!!! Especially if you don't hook up the blue wire.

Dude........... xc16 only has Y1, Y2 and common to hook up to.


how many wires do you need????????

According to the Lennoxdavenet.net , You have to have FOUR wires for the outdoor and indoor to work properly!!!

There is a blue wire in the outdoor unit that tells the A/H it is in second stage. If it is not hooked up it won't work!!!

I will tell my supervisor to get me a 2 cool 1 heat thermostat with dehumidification control. Then the customer will be getting what they sold him.

according to this diagram http://tech.lennoxintl.com/PDFs/535286wia.pdf


there are only 3 wires to hook up on this unit.............

he is working with a gas furnace and straight a/c right?????



you may be thinking of a xc21 unit with the protection module, they need 4 wires.

you still have other problems, you should at least be able to make it run on low stage with what you have......

According to RDP the pro 8000 will serve you well.

the guys who done the trim on it were not communicating well with each other. (that is a little obvious though) When I first got there they did not even use the same colors. So, I had to rework all the wiring. I guess I still need to rework all the wiring. This house has 4 units and they are all the same type. So, when I get it figured out I should be able to get the others one right away.

The link I found said 4 wires. But it didn't list them. I found another that did. C, Y1, Y2, and L. L is not used unless a communicating stat is used. Sorry!!

XP16 has the blue wire I was thinking of.
