Smart Color Scroller Fan control

The short question: We are trying to adjust the patching on a number of Apollo Smart Color Pro 7.25 scrollers on our ETC Ion console. With the current settings, I don't believe the fans are operating. When I choose the scroller type, Smart Color 7.25 Pro, there are 6 options. What are the differences? or better yet, which one should I click?

The long question: When looking at the setup of the scrollers, they are currently patched as Smart Color 7.25 (not "Pro", no fan) and I am concerned about heat buildup and the fans not turning on. Many of the lamps are plugged into dimmers/addresses that are sequential (ie. 130, 131,132,etc. with scrollers on part 2 addressed to part 1 plus 200. So channel 130 is a dimmer (part 1) with the scroller (part 2) addressed at 330. This is all fine except that if I try to patch them as "Apollo Smart Color 7.25" and choose "Fan," (requiring 2 addresses) the scroller FAN is addressed to part 2 plus 1, which creates a conflict with the scroller attached to the next fixture. Many of the scrollers are in very difficult to access locations, so I am hoping there is a solution at the board where we can tell the fans to operate without having to access every scroller and readdress them.

Thank you for any help with this.

    i think this is another one of those moments where there is a good and a bad message:

    the Apollo Smart Color Pro 7.25 scrollers do have fan control. the fans can be controlled in various ways according to the manual. either on levels 1, 2 or 3 which is a fixed speed you set at the console. or with the option PL1 which makes it controlled with an additional address per scroller, which is what you said you want to avoid because it would mean readressing all scrollers. the last option is called 512 which makes the scroller fan listen to address 512. you can use that for all scrollers, which means less individual control but can save addresses.

    so back to the good and bad message: you can get fan control, but you will need to get access to the scrollers. either to just activate the option 512 or to activate PL1 and change the scroller addresses.

    before you go through too much trouble though i would check if some clever person in the past already had activated the 512 option. so bring up address 512 and check if the fans turn on. if they don't unfortunately it looks like you have some work ahead of you
