    attached is the closest i could get to swahili

    You are quite the individual multi functional real men of genius we salute you mister swahili interperter.
    Arguing with your Boss is like wrestling with a pig in
    mud.
    After a while you realize that while you are getting
    dirty, the pig is actually enjoying it.

    It is not exactly cheating, I prefer to consider it
    creative problem solving.

    Hmm

    this chiller does not have 'softload'...at least not like it is applied to the other screw chiller products.

    Jay is correct , but what I was referring to was you could send it a variable current limit signal over a set time period and do the same thing .

    I still would like to know how adding extra Ct's will solve his low evap temp issue though ???

    If im not mistaken the RTAA UCP2 has phase unbalance & phase reversal already, Just need to confirm its enabled under setup menu.

    Ya'll are right its standard ambient unless low ambient option has been added.

    What is your chw setpoint, what is the ambient condition its tripping????????

    Anyone open a control panel just to find a rats nest of wires and wonder how that could happen?

    graham, It's too cold in Canada for that Healey. I think it would be happier if it were parked farther south. I know a perfect garage in Va.

    You mentioned low evap alarm and other problems due to low ambient conditions. Do you really have isues or was this just a jab session??
