    Installing Honeywell RTH230B thermostat
    I'm having trouble installing a Honeywell RTH230B thermostat. When I took off the old one, I properly labeled the colored wires and turned the electricity back on, but the furnace won't kick on.
    I checked to see what color wires are coming out of the furnace, and it's just two of them-- green and dark blue--even though the old thermostat had more than that hooked up.
    If I should be going with the two-wire hookup, the instructions say I should be taking out the RH/RC jumper, but the old thermostat had the jumper connection in there, so I've left it in so far.
    Any thoughts on my next step?

    If you do a search here, you will find many other people having trouble with that thermostat. If the furnace has terminals labeled R and W, you want the 2 wires connected to them connected to the RH and W or W1 at the thermostat. Some people had to change batteries to get it to work. Let us know how you do.
