    Installing a programmable thermostat
    Im having a problem installing my new programmable thermostat. The connected wires on the old mercury one are Y, Rc, W, B, G. The ones on the new one are G, Rc, Rh, Y/O, W/B, Y1 and I can't figure out where to put them off the diagram that they sent in the package.
