I'm planning to replace my old mechanical White-Rodgers thermostat (model
1C30-302) with a Honeywell Chronotherm IV.

My house has gas heat only, and uses a 24-volt 2-wire system (white and red
wire). This should be an easy DIY job, but I found the labeling on the old
thermostat confusing.

The old sub-base has 2 connections: one is labeled "4" (connected to the red
wire), and the other is labeled "R5" (connected to the white wire).

I know I need to connect these to the "R" and "W" terminals on the new
thermostat. Unfortunately, the terminal cross-reference for the new stat
don't mention an R5 terminal. So, I don't know which wire should go to
which terminal on the Honeywell.

I suspect since it's just a 2-wire system, it doesn't really matter which
wire goes to which terminal (as long as I connect to the R and W). My guess
is that the thermostat just makes/breaks the connection between R and W when
the stat calls for heat.

Should I just hook the Red wire to R, and the white wire to W?

Thanks,
David Bono

your kidding right?


go troll elsewhere

To get the Chronotherm IV to work correctly, you will need to run 2 more
wires
they will need to be wired as follows;
R - 24V
W - heat
G - fan
X - common

Then you will need to do the initial installer programming on the stat, and
then program it for your personal comfort and times

According to the installation instructions, the Chronotherm IV should work
with the existing 2-wire system.

Since the existing thermostat doesn't have a separate G terminal, I assume
the furnace takes care of turning the fan on and off.

What if the system doesn't have the G and X wires? Does that mean I can't
use this thermostat?

Like I said... you will need to ADD 2 more wires to get the Chronotherm to
work *correctly*

this is Turtle.

Look Let me explain this is Coon ass Language for you.

The G terminal --- Forget about and play like it is not there.
The R Terminal --- tie it to the wire that was tied to the R terminal on the
old thermostat.
The W terminal --- Tie it to the wire that was tied to the old thermostat
where it was on the W terminal.
The X terminal --- Tie a wire on it / X terminal and run it back to the
Ground side of the 24 volt transformer in the furnace or to the C terminal
of the furnace or if you have to / not recommended but tie it to the frame
of the furnace.

If you have not got a pretty good grip on the ideal here by what Noon said
and my words do get you knowing exactly what to do. You may look to get a
hvac service company to wire it for you.

The Below here really explain everything you need to know , but just forget
about the G terminal like it was not there.

Hook your red and white wires to the R and W terminals of the new
stat. As long as you have the battery powered or power stealing
version it will work just as it is supposed to.

Since you don't have A/C there's no need to run two additional wires
and there is no such thing as an X terminal in a standard Chronotherm
IV as someone else stated. The stats that require a Common have a C
terminal.

If you want to take advantage of the Fan On feature you'll need
another wire for the G terminal. If your furnace is old you may not
even have a G terminal to attach it to, if that's the case you'll need
to have a professional install a fan control center. Either way it's
not worth the time...if you add A/C in the future the installer will
run a 5 wire at that time.

Good luck!
George

Here is a link to the White-Rodgers WebSite where you can find your
thermostat listed and then find the wiring connections appropriate in your
case.
