    Carrier chiller controls?

    The facility Im at is looking to up grade the existing Carrier CCN chiller controls to i-Vu. At a resent contractor meeting several items were discussed but mostly it came down to energy savings. Can the i-Vu controls shut down a small chiller before starting a larger one? We were told No, a larger chiller will start on ACR then the smaller one secures.
    This running of 2 machines = a higher KW demand and higher operating costs. (Several thousands of $s a day)

    Other then i-Vu what are our options for chiller controls?

    I have found the Carrier CCN to be very reliable. The local OEM office has one of the best programmers I know of. Your mileage may vary.

    Which CCN controller are you using presently to control both chillers.
    Flotronic System Manager or Chiller System Manager

    Just configure the lead chiller to 100% before starting the lag chiller this is in the CSM. The I-VU is not a controller but a means of viewing a system remotely either on site or through the web allowing you to be able to change various items in the system control
