Good evening.

Our old thermostat was model T8195B which came with wires C,Y,W,R & G. has no rererence as to where they hook up. The new one RTH230B doesn't say where these wires go. I've removed the Rc/Rh jumper according the instruction manual. Nothing went on at all. What can I go

Thank you

Just in case you lost your directions I took the liberty to post them below

All the wires are listed in the directions so I would read them to make sure you wired the thermostat correctly.

The only wire no listed is the C but it is only for the old clock transformer that you do not need to use with the new stat.

There is a toll free phone number in the instructions on the lower right side at the bottom. Call honeywell they will have your answer.

NOTE: There are a few setting that you will have to do. They are also described in the instructions.

HINT: RH and RC since you really only have a 4 wire system to start with you need to reconnect them.

BTW here is the old thermostat wiring so you can compare wiring.
