Intelflow VS pump with Aqua Logic controller only runs for ~ 15 mins

[DaveHog]

When I hit the Filter Pump button on the controller, the pump primes and runs for ~ 15 min, then the pump loses power and the controller filter pump light goes off. If I hit the Filter Pump button again, the same thing happens.

Also, the controller starts the pump at 11am and quits at ~ 11:15am, when it should run until 4pm. The pump is on program 1 which is Manual 2400 rpm. I see some alert codes of F90052 low power/voltage. Is my pump bad, is a relay in my controller bad?

Are you using a relay?

 

[DaveHog]

Yes, and I'm going to bypass the relay today, and try it.

Intelliflow pumps need constant power and should not be switched with a relay.
AquaLogic = older Hayward. They would barely communicate with their own VSP, two speeds only. Won't communicate with a Pentair directly. You can get an IntelliComm2 to get more control.

Agree. Bypassed the relay... the Intelflow VS pump.... Is working great. Thx so much!
