I currently have a Janitrol digital thermostat. I can't read the model #. It has 8 terminals and 7 wires hooked up.
Terminal - Color
Y - Yellow
Com - Blue
R - Red
G - Green
w2 - Looks white
E/w3 - Looks pink
O - Orange
B - Nothing

I'm trying to replace it with the Honeywell RTH230B with terminals as follows:

Rh
> Jumpered
Rc
W
Y
G

Can I install the Honeywell or do I have to go buy a 7 wire thermostat? If I can install it, what wire goes where and what wires do I no longer need?

I have a central Heating and A/C. No gas. No pumps.

Nix that. I do have a heat pump. From more research I have done, I cannot go to another thermostat. I'll need all wires. Thanks to all that looked at this post and thought about it.

As far as I can tell, nobody ever answered his question - and I have the very same dillema. Now, in my case I have an AC/Heat Pump combination unit outside, and a Natural Gas furnace inside (strange, I know, but it's cool to have a backup).

Anybody have the answer? Thanks in advance!

The new stat is not for heat pump. You will need to get a heat pump stat.
