Taco VT2218 OverVoltage

Hi Everyone,

I currently have my TV2218 circulator hooked up to a ZVC406 and recently I've been getting a AC input overvoltage error on my circulator. What should I be looking at that may be causing this error?

    I think the first step would be to check your voltage. While you are at it, make sure the neutral is good, it should have continuity to ground and should not show voltage when isolated. If your voltage and neutral are normal, a call to tech support would be in order.

    The VT2218 is a great pump. Contact Taco Tech Support at 401-261-4890 for help with that product. Not sure how you have it connected to ZVC control

    As Zman said, check your incoming voltage. You might be experiencing voltage spikes causing the over voltage error code. Also check the connection going to the pump. Any questions please call into Taco Tech Support @ 401-942-8000

    Do you have a mod con boiler? Most will alert you to an out of tolerance voltage issue. It would help run down if it is a supply issue.
