    Problem with Honeywell RTH2300 thermostat

    I installed a new HOneywell thermostat in my house, heat only (2 wires: R & W). The thermostat is kicking the furnace/fan on for 10 second intervals, with 10 seconds in between, over the course of half an hour (usually when transitioning from cold to warm modes. i.g. leave to return). It's quite annoying, and mechanically I'm sure it's not good for the furnace. Has anyone experienced this?
