I have a gas furnace equipped with central air.The compressor is shot in the AC unit,and I needed to replace the thermostat so I bought a heating only thermostat.I have the blower and the w wires together on the w terminal designation and the rh on the r terminal designation, and I have the y wire taped off and useless. The system works except the blower seems to come on first and run for a while before the heat kicks in. example: This morning I noticed the blower running and blowing cold air,so I looked to see if the pilot was still lit which it was,then I turned the thermostat up a couple of degrees and the heat kicked on.when the house reached temp. the heat and blower shut off together. Any ideas or is this normal? Thank You

For heat, normally all you need to connect is the red and white wires to the terminals. Internal wiring should start the blower after a delay just as it did with the old thermostat. Don't know to say about the blower running in the morning. Perhaps the relay stuck. Post back if you have more trouble with it.
