    Hello Justin,

    This maybe owing to a few things.
    The first thing to check is to see if the cooling output has been configured correctly.

    To do this you will need to go into Config Level and Page to the slot you are using for cooling.
    So if your cooling wires are attached to 2A and 2B, Page to 2A.
    Using the scroll key press this to check the function "Func".
    This should be set to Cooling.
    Scrolling down the list further I suggest ensure the following is set.

    Val.L = 0
    Val.H = 100
    Out.L = 0
    Out.H =100

    If this is all a bit confusing you can always call me on our support telephone line.
