White Rogers to ICM Thermostat

[Porkface]

A question for those who have replaced their stock White Rogers thermostats with the ICM garage thermostat. How did you wire it?

In my FWC, the White Rogers (WR) has one wire to the W terminal and one wire to the RC terminal with a red jumper wire from the RC to RH terminals.

Referring to the ICM instructions, I've connected the WR-W wire to the W terminal on the ICM and the WR-RC wire to the R terminal on the ICM. I did not install a jumper.

Performing the quick tests in the ICM instructions, the furnace starts when I raise the thermo. temp. The fan starts properly. When I try the Fan On test, the fan does not start after waiting 30 seconds or so.

Any suggestions?
Thanks,
Tony

I don't believe the fan will run by itself. I think it only runs when heat is called for and/or the combustion chamber itself is still at or above a certain temp.

Oh.... Thanks for the info!
