I'm replacing an old honeywell thermostat with the clock and peg set up with a new digital. The old one has the standard 4 wire heating and cooling- on the old therm I have an r wire white jumped to C, a blue wire W, a black wire on another C , and a red wire with no letter. Then new one has RH heating supply,RC Cooling supply jumped , W heating signal , Y cooling signal, and G Fan. I tried hooking it up and the heat stays on I need help. The new therm was set lower than room temp.
