    New Thermostat
    I bought a Honeywell RTH230B thermostat and did not follow instructions very well... I took the old wires off without labeling them and now I don't know what color goes where!! Please help... I have 4 wires; Black, Orange, Red and what appears to be Yellow but might be White... the thermostat reads RH, RC, W, Y and G... can ANYONE please tell me which color goes where?

    Go to the furnace and hope it is labeled R, W, Y, and G. If so, connect the wire connected to R at the furnace to RH &RC at th thermostat. The W to W, etc. Also see the sticky at https://www.askmehelpdesk.com/heatin...ons-58313.html
