To fully use the Gyre and Apex you’ll need an IceCap interface
module.
Without that all you can do is do is cut power to the outlet for the controller and pump, just like unplugging and plugging back it. In your case looks like outlet 6 on your EB832.
In the pics above, you have control type set to powerhead. So it gives you the configuration for those times (initial on time, off time, on time) and they are sequential. This means the pump will be off for 5 minutes, then on 5 minutes, then off 5 minutes. Then it will repeat. So it means on for 5 minutes and off for 10 minutes every 15 minutes.
The feed timer A means that the outlet will be off any time that feed A is on. The feed time delay set to 5 means the outlet won’t turn on until 5 minutes after feed A ends.
Also you need to put the outlet in Auto for this all to happen. If the outlet is set to on, then it ignores this and just turns the outlet on.
I recommend not using this control type on your gyre. I’d use the control type as return pump. It will make the outlet always on but still give you the feed timer ability.
