How to get a smoother ramp in constant flow mode?

I'm using the XF 250, and the constant flow option. I have a few programs set up, so that it changes flow rate throughout the day. Say from 10%, to 20%, to 30%, back to 20%, and then back to 10%.

Its works. But the ramp up bewteen the different flows are not very smooth. It goes from 10% to 0%, then 20%. And from 20% to 0% then to 30%, when it switches between the flow rate programs I have set.

When you use the pulsating mode, it will go smooth from one flow rate to another. why canøt it do the same in constant flow mode?

It startles the fish, every time it switches from one flow rate to another, using the constant flow mode. I want it to go from 10% to 20%, without going to 0% first.

Any suggestions?

Sounds like you have the controller set to "Gradual Pulsing" mode instead of "Pulsing" mode. Change it to pulsing mode and the controller will do what you are looking for.

Its on constant mode. When it goes from 10-20%, it goes to 0% first, then to the desired flow rate.

What you describe is exactly what Gradual Pulsing does. Are you certain that you have it on Pulsing only. The to icon are very similar.

Im pretty sure its a straight arrow. My program is like this.

1. 9:00: 10%
2. 11:00: 20%
3. 13:00: 10%

When it switches between these flow rates, it first stops completely, and then (after a split second) starts at the next flow rate.

I want it to go straight to 20%. Not stop completely first. In Constant Flow Mode.

The problem lies in the programming i think. When it goes from an automated program 1 to 2, the controller is trying to figure out what the next setting is all about, and when it knows it starts. While making this new decision, it goes to 0%, and then ramps up to the next setting. All this happens quickly and within a second of cause, but it still goes to 0%.

If I only have 1 program on say pulse mode. It will then pulsate smoothly between high and low, without ever going to 0%. But if I add another setting "2". It will stop completely for a split second, and then continue with the next setting.

My point is, whatever that new setting is, I don't want it to stop completely, I want it to continue with the new setting, and not hesitate in between programs. I hope it makes sense.
