HVAC Pros Ask...
Question: I have a gas boiler with Taco controls that is short cycling. The problem seems to relate only to the 2nd floor zone. What can be causing this?

Answer:
Check the heat anticipator on the thermostat for the zone or zones you think are short cycling. The thermostat should be on an inside wall, with no radiation under it, and away from outside drafts. Also check that there are no bad connections and that 20-gage wire is used, not telephone wire. The current draw should be about 1 AMP. When the boiler cycles, watch the water temperature to see if the boiler aquastat is cycling the boiler. The upstairs zone might be small and not much of a load on the boiler. You might want to lower the boiler water temperature until the outdoor temp drops. Our PC700 is an outdoor reset control used in conjunction with our -EXP controls.
