Hayward OmniPL 5th valve?

[Craig710]

Is there a way to add more than the 4 actuator valve to a OmniPL?

Not directly. Hayward wants you to use the Omnilogic if you need more than 4 actuators.

Or you can control an actuator using a high voltage AUX relay using this circuit. AUX relays use two wires - 24 VDC and ground. Valve actuators use three wires - two 24 VAC lines and ground. AC on one line will turn the valve one way and AC on the other line will turn the valve the other way.

You could use the AUX relay to control the 24 VAC so that it will turn the valve using the following circuit. But normal AUX relays won't work as they do not have any Normally Closed contacts. You need to change a relay to one that has NC and NO contacts.

Why does it need to be NC?

Why does it need to be NC?

To route the power to turn the valve the opposite way.

Otherwise the actuator will turn one way and never turn the other.

couldnt you just flip the switch on the actucator?

Then what is the purpose of having the actuator if you are flipping the switch on it?

Pentair 520198, 2-speed relay, has NC and NO terminals and will plug into a Hayward board.
