Anticipator Setting

Just installed new Taco zone valve but am not sure if I should set the thermostat anticipator at the boiler gas valve current (0.5 amps) or Taco valve current (0.9 amps)? Taco recommends the 0.9 amp setting. Recommendations would certainly be appreciated.

    0.9 is your setting.

    Be careful,

    if it's a 555 it needs to be at 0.9 which is the left side of the scale on a T87, but if it's a new ESP it should be at 0.09 which is the right side of the scale. BTW, the only correct way to do this is with an meter, FACT!

    And .9 is only a starting point

    Most hydronic systems work better with longer run times. If I remeber right this will give you a cycle time of 6 times per hour. Most systems work better at 3 to 2 per hour. I typically set the anticipator as high as possible and then turn it back as needed to achieve smooth temp control.
