    I know this is a older thread but did this ever work?

    Hello All & Merry Christmas! I'm looking to add a GHL Propellor Breeze fan along with the Propellor Control 2.1 Controller. I would like to plug this into my Apex 0-10v port.

    First, before purchasing, is this all I need along with a program statement such as below?:

    Set OFF
    If Temp > 79.0 Then 10
    If Temp > 79.1 Then 20
    If Temp > 79.2 Then 30
    If Temp > 79.3 Then 40
    If Temp > 79.4 Then 50
    If Temp > 79.5 Then 60
    If Temp > 79.6 Then 70
    If Temp > 79.7 Then 80
    If Temp > 79.8 Then 90
    If Temp > 79.9 Then 100
    If Temp > 100 Then 10

    The program is Ok, but I question the use of this last line. What is your intention?

    If this is in case the temp probe fails with a > 100 reading, then I’d use Then OFF instead, rather than forcing some cooling when it might not be needed.

    Thanks Russ.

    The primary question I had is that would the GHL fan and controller cable work and be compatible with the Neptune 0-10v port by simply plugging in the cable with no other mods? I just copied and pasted the program from my post from one of the OPs above and will take your advice on using the OFF statement potentially. Thanks!

    Hi again - just following up. Has anyone successfully connected a GHL fan and controller cable work to a Neptune 0-10v port by simply plugging in the cable with no other mods? Here are the links to the fan and cable:

    No. The connectors are different... they are similar is style but are different in size and number of pins.

    Ok thanks Russ. If anyone on this thread has had success making their own cable, I would be interested in purchasing one from you. Please PM if so. Thanks.
