Intellicenter question: pump operation and feature circuits vs pool circuit

Hi, I am still dialing in a new Intellicenter (with VSF, IC40, MasterHeat). I have spent lots of time searching and wasn't able to find this exact question.

Currently the pump is not wired exactly right, it is wired to the load side of the pump/relay so it loses power when the pump goes off. My installer is going to fix that so the pump gets constant power while the SWG runs through the relay, so it powers down when the pump doesn't run.

I am having another issue with setting up schedules and I can't figure out if it is related to the wiring issue, or just how the system works.

I set my pool circuit pump speed at 1800rpms for now (the min for my SWG seems to be 1600). I also set up a feature circuit for 2500rpms for skimming (although man this thing skims pretty well at 1800rpms), and another for full power, just for fun. My issue is that my 2500rpm circuit doesn't do anything (pump doesn't turn on) unless my pool circuit is also running. Is that how the system is supposed to work?

At first I thought maybe this is because the pump relay is not tripping without the pool circuit on, so my pump gets no power due to the way it's wired. But if that's the case, then even if my pump gets constant power, how will the 2500rpm feature circuit tell the pump (and hence SWG) to turn on?

If it is working right, then I guess you just always need your main pool circuit on anytime you run your speed circuits? I suppose for scheduling purposes you could either always group a speed circuit with the pool circuit, or just set the pool circuit to run 24/7 since it's the lowest speed, and then count on the "higher speed takes preference" feature to use the 2500rpms for skimming cycles a couple times a day.

Anyone, if anyone can clarify how the pool vs feature circuits are supposed to work via the pump, when the wiring is correct, that would be helpful. Thanks.
 
Big,

The SWCG should only run when in the Pool mode or Spa mode.

The pump will only automatically run if a couple of things happen.
1. An active "Circuit" must be scheduled to be on. This is usually the Pool or Spa circuit, but it can be any circuit..
2. The Active Circuit must have a speed assigned to it.
3. You can't be in the Service mode.

As an example.. Rename a feature circuit to "Jim" and assign a speed of 2500 RPM to the Jim Circuit. Schedule Jim from 10 am until 11 am.

At 10 am Jim will wake up and run the pump until 11 am when he goes back and takes a nap.. :mrgreen:

Thanks,

Jim R.
 
Thanks Jim. Ok so using your example, with correct wiring let’s say Jim’s 10-11am run is the only thing scheduled. Meaning the pool circuit is not scheduled to run and has not been turned on manually. At 10am you are saying the pump should come on at 2500rpms but the swg should not turn on? And then at 11 the pump shuts off obviously.

With my current wiring Jim would just keep on snoozing at 10. If I understand correctly, sounds like once I switch my pump’s power to the line side of the pump relay everything will be working properly.

But I’ll still prob never use the Jim feature without also running the pool circuit, since I want that swg pumping.
 
Because your pump is wired to the load side the pump/filter relay, it will not have AC power unless the Pump/Filter relay closes. It will only close if you are in the Pool mode or Spa mode.

I assumed that was just a temporary problem.

You could fix it in about 30 seconds. Just move the pump wires from the load side of the relay to the line side of the relay and you are good to go.
