Question about Hunter Heating & Cooling
I have a 95% efficient furnace installed in 2009. I have a digital Hunter thermostat with typical wire coding. RC; R; GN; WH; BL. This new thermostat has: R; I-; I=; C for connections. I assume R is the Red wire. What wires do I connect to the other 3 connections/ The furnace has no wire on the "C" connection, and Blue wire is on the "Y" connection. Thanks for any assistance. I can't believe Lennox does not explain this in the connection procedure and their customer service has absolutely no technical assistance. If I could, I would take this back and get my money back. Poor customer support is a big issue for me.
Sounds like the i comfort tstat which is a communicating tstat. You would need to purchase the interface module to connect your legacy style furnace to a communicating tstat. Yes r is 24v and c is common but i+ and i- are data wires.

Brown my friend is for the 4 way valve solenoid, that is if you have a heat pump, ( it uses freon for heating instead of natural gas) perhaps you got the wrong thermostat, if you have a brown you need a thermostat for a heat pump, a regular thermostat is not going to have a brown connection.

Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters

Connect the red to RH
Go down to the furnace and look at the circuit board and note what color's go where. Most units only use 4 wires.
RED to RH
YELLOW to Y
WHITE to W
GREEN to G
Then from there two wires go to condenser outside. And they connect to Y and C on the board. Most of the time Red and White from outside. Don't get confused with Red coming from thermostat. Let me know Ken

SOURCE: Need help with wiring thermostat
first do you have a heat pump unit or standard a/c? standard a/c connections at the thermostat go like this red wire to rh-rc which is the 24v power and you don't have to remove the jumper.white goes to w which is the heating wire yellow goes to y which is the cooling wire green goes to g which is the fan wire and blue goes to c which is the common wire. so if your stat has rc- rh ywgc you should be set if the wires on the furnace correspond with the same alpha designation.orange may be used if u have a heat pump unit otherwise it may just be a spare you cap off and leave behind the subplate.
