Taco Bumblebee Circulator

I added this circulator on a boiler I installed on my cousins boiler after hurricane sandy. My question is does anyone know how I can pique performance out of it. The boiler is a 3 section slantfin w 1 baseboard zone and 1 indirect hwh as well as a Honeywell outdoor reset. My cousin lost the literature and to be honest didn't fully understand it anyway.



Any ideas or should of I just bought a 007?

    How are you using it. What mode is it in? Sensor?

    I believe I have it in delta t and its 20 degrees but it comes back I think half maybe less than half even w both zones running

    Sensor

    Is the sensor in the proper location? Is it secured and insulated?

    A 10 degree delta T is not a bad thing. The circ may be running at it's lowest setting.

    Are there performance issues?

    delta T mode

    You might be in the constant speed mode, have you verified your in Delta T?

    for your reference I attached the latest instruction sheet.  Page 3 gives specific instructions on verifying delta T mode.

    Performance

    As Carl said, is there an underlying issue, that is making you look to the circ.? Uneven heating? A 20 degree DT in a baseboard series loop can give you that. The circ may be running at its minimum, and most of the heat given off at the start of the loop.

    Heat Loss

    Well it sounds like you are here on Long Island or in New Jersey. The heat loss of the house has dropped dramatically. How big is each zone?



    That makes sense since it got a little warmer here the last few days. The BBee is probably running on the lowest speed.

    If the house is warm and comfortable, then you are doing great!

    hey Joe

    thanks for the updated manual.



    I've not seen that elevation caution before?



    In addition to pre-charge adjustment the exp. tank may need to be upsized?



    On a 30 gallon capacity system from 12- 20 psi increase takes the tank from 2.8 up to 7.5 gallon expansion capacity, running 60- 180F water temperatures.

    Thanks

    Yea I have it set for delta-t at 20 degrees but comes back w 10 degree difference. I know I can set to more or less "concentrate" on kilowatt used.



    Secondly I was wondering if the bumblebee circ was overkill



    And thirdly long islands lowest temp would be 10 degrees when I set the osr for that its freezing so I set it for 20 but that doesnt defeat the purpose?

    Delta t

    You can try to slow down water flow by playing with ball valve on pump discharge. It might bring pump to the controllable range.
