Hayward Northstar 2 speed 2 1/2 HP pump.
Hayward/Goldline AQL-PS-8-X288 Automatic Controller
2 Speed wiring is correct according to manual using the second aux relay.
I found that a 1 speed motor had been programmed so I change it to a 2 Speed motor by properly selected it in the Menus config. section for both SPA and Pool Filters.
Verified proper programming.
Verified proper wiring of the pump relay and low speed relay.
Low speed has never worked and has been running the pool for 3 years without the cost savings of a low speed filter operation.
High speed is always initiated and wiring is hot on terminals 1&2 as shown on motor plate(1 is common 220V)
Switching to low speed (pushing button) causes the low speed relay to apply power to the low speed motor winding (terminal 3) but the High speed remains hot as well on motor terminals (2). This causes the motor to pop the resettable breaker after a considerable hum.
Testing with voltmeter:
I disconnected the motor , engaged the low speed and verified that both terminals 2&3 on the motor were hot with respect to terminal 1 (common)
Also the low speed relay drops out after 3 minutes which is what is supposed to happen to the high speed but this relay only turns on when manually selecting low speed.
Has any one seen this problem before when using the Goldline (now Hayward) AQL controller. Is there a problem associated with programming the AUX relays?
