Do you want the Gyres to alternate between forward and reverse? If so, you also need the special Alternating Gyre Mode cable (which does not ship with the IceCap module). See
https://www.bulkreefsupply.com/alte...d-cable-for-gyre-interface-module-icecap.html
Here's how I have mine set up, using Alternating mode:
1. Create a profile for the Gyre speed. Be sure to Enable the Synchronize checkbox:
(I created an additional profile for slower speeds at night, named GyreSpdNit)
2. Create a profile for the Gyre direction. Be sure to Enable the Synchronize checkbox:
A value of 0 runs the Gyre forward, and 100 runs it in reverse.
3. Configure Varspd1 to use the speed profile:
Fallback ON
If Time 07:00 to 20:59 Then GyreSpdDay
If Time 21:00 to 06:59 Then GyreSpdNit
If FeedA 000 Then OFF
If Output vFeedFish = ON Then OFF
4. Configure Varspd2 to use the direction profile:
Fallback ON
If Time 07:00 to 20:59 Then GyreDirDay
If Time 21:00 to 06:59 Then GyreDirNit
If FeedA 000 Then OFF
If Output vFeedFish = ON Then OFF
Since you have two Gyres and modules, just add the same code to Varspd3 and Varspd4 if you want both Gyres to run the same programming. If you want them to be different, you can assign different profiles and times to each.
Just set each of the Varspd outputs to AUTO. I also renamed my outputs to GyreSpd1, GyreDir2, GyreSpd3, and GyreDir4 to better identify them.
Let me know if you have any questions.
