    Honeywell stat question (SE)

    I just had a call from a customer regarding a T8775A1009 Digital round thermostat. It sounds to me like the cycle timing is screwed up because the stat will cycle off and right back on, never quite hitting the setpoint. There are dip switches on the back that look like adjustments for different types of heat, F/A, hot water, etc. but he doesn't have the manual anymore and I've never used this stat. Any one know what the switch alondside the dip switches does? Is there an actual anticipator on this stat?

    Thanks

    Those dip switches replaced the anticipator, dip swith 3 is F/C, the dip switch on base is fuel F gas/.oil E electric/HeatPump, however check the batteries, they give all kinds of wierd problems as they start to get week, even new out of the box batteries.
