Evcon 3600-367P to Honeywell RTH7500D

I have a heat pump with electric emergency heat.

On the Evcon thermostat, I have:

O - White
R - Red
G - Green
Y - Yellow
W2 - White
X - Blue

There is no X on the Honeywell. Where should I hook the blue wire?

Thanks

Welcome aboard.

X is "common", you can use that on C.

Here is how the wires will match.

Old----------New
O - White---O/B
R - Red------R/Rc
G - Green---G
Y - Yellow---Y
W2 - White--Aux w/ jumper to E
X - Blue-----C

System set up menu.

170-7
180-1
190-0
240-3 (If it shows up.)
270-3

Let me know if you have questions on the rest of the settings.

Thanks Jay.

Two things

1. Should R go to R or RC (the Honeywell has both)

2. What do you mean by jumper (W2 - White--Aux w/ jumper to E)? I assume you mean wire Aux and E together? What gauge wire should I use for this?

Thanks

It don't matter.. Either one since there is a jumper wire in place.

You can use a small piece of t-stat wire between Aux and E, and white can land on either one of those two slot.
