    Honeywell RTH230B Wiring
    I've seen lots of questions here about this and the answers were somewhat useful, but I can't get my new RTH230B thermostat to work.

    My furnace has W,Y,R,G wires going to the thermostat. All were colored correctly, except for the R connection which has a Blue wire. The thermostat has a RH, RC, W, Y, G connections.

    I wired the W to W, the Y to Y, the G to G and the R (blue wire) to the RH which is also jumpered to RC.

    As of now, the fan comes on but I can't get the heat on.

    Per a previous post, I have just put new batteries in it also. :)

    Any help is great appreciated.

    Thanks,

    GW

    You say the fan is running all the time? And all you did was change t-stats? No problems pryor to that?

    Check to see if the instructions mention hitting a reset button on the stat after changing the batteries.
