Hello,
I recently bought a new furnace and need help hooking up the thermostat and power. I have a very basic understanding of wiring, but don't want to mess this up. Any help will be greatly appreciated. Here's what I have:

Furnace model number: E3EB-015H
Power supply 240VAC 1Ph 60 Hz
4 speed
I am using a jumper bar
Thermostat: Honeywell Chronotherm IV Plus
4 wires connected which went to the old furnace,
(Intertherm 015HA):
G,Y,W,R
Outdoor Coil: Lennox 10ACB24
Has one Red (L1) and one White (L2) wire which were also hooked to the old furnace.

I'm having a friend replace the freon, but I'd like to hook it all myself. I can post wiring diagrams if needed. Thank you!

I looked up the Miller unit, and noticed it is for a mobile home. Does the unit have a terminal board (Usually by the blower area), with the G,Y,W,R? One easy way to wire the tstat is to use the color coded tstat wire, 4 wire usually has a green, yellow, white and red wire. Follow the same pattern, hook the green to the G, Yellow to the Y, W to the white, Red to the R, on both sides, Tstat and furnace. If you do not have the same colors, just make sure you hook the colored wire to the same spot on the furnace and Tstat (Match them) Do not hook Y at the tsat to w on the furnace, common mistake. Then take tstat wire from the furnace to the AC condenisng unit (2-wire will work, if not, run 4 or 5 wire and just use 2, usually white and red) Hook the red wire to the Y in the furnace (this is the cooling connection) and the white goes back to the common side of the transformer, usually designated as C. The Lennox unit will have 2 wires with wire nuts on them, the 24 VAC you ran from the furnace goes to these 2 wires, they should be in a small junction box near the contactor within the condensing unit. Good luck with it. Pat
