Controlling valves with Intelliflo3 VSF relay board

Greetings, currently building a pool, and I have an Intelliflo3 VSF pump with the add-in relay board. Plan to use the pump for some simple automation.

Has anybody had success in using this setup to open/close valves on the system? I'd like to install a single actuator on a valve, but can't seem to find a way to do it without installing a "full" automation system (such as the intellionnect).

The main problem is that the valve actuators are 24v, but I can't seem to find any 24v transformers for pools (without installing a full automation system).

Thank you!
 
Q,

The IntelliConnect does not have any valve functions...

You can use the relay in your IntelliFlo3 to power the following circuit that will control a valve actuator. It would (edit).. turn on the Aux relay in the circuit below. You don't need a pool rated transformer to power the actuators.

Thank you for the reply! This is very helpful. I was under the impression the relay board for the IntelliFlo3 was intended for 120v AC connections, but it makes sense it could handle 24v as well.

The "auxillary relay port" on your diagram shows 3 wires (the "24v out", and two wires going to the valve itself (red and white)). In everything I see, the Intelliflow3 relay port add-on only has 2 ("Supply" and "Device"). Does the "24v out" line get connected somewhere else in the pump?

(Don't worry, the electrician will wire everything, not me. I just want to make sure I get all the right parts first...)

So will any old 24v transformer do for the actuators? For example, this one?

Q,

The transformer has to supply enough current to move the actuator... 2.5 amp should be plenty of juice.

To be clear.. The relays in the IntelliFlo3 are only have a Normally Open set of contacts.. The IntelliFlo3 relay would be used to turn on the relay in the above schematic, which has a Normally Open and a Normally Closed set of contacts.


Thanks,

To be clear.. The relays in the IntelliFlo3 are only single pole, so they only have a Normally Open set of contacts.. The IntelliFlo3 relay would be used to turn on the Double pole relay in the above schematic, which has a Normally Open and a Normally Closed set of contacts.

Thank you again for your response. Pardon my ignorance, but I'm not able to envision how this would be wired...

Are you saying that to control one valve actuator would require two "ports" on the relay? (One to open the valve, and one to close it?)

Yes...

Voltage would go through the IntelliFlo relay and be sent to the "Aux Relay coil" shown in the above schematic. This would turn on the aux relay and move the valve in one direction. When you turn off the IntelliFlo relay, the Aux relay would also shut off and the valve would move in the other direction.

You will need to buy a SPDT relay and a 24 VAC power supply. To make things simple, the SPDT relay that you buy needs to have a coil voltage of either 24 VAC or 120 VAC.. If you use 24 VAC, you would wire the 24 VAC to the Line (input) side of the IntelliFlo relay. If you use a 120 VAC relay you would wire 120 VAC to the Line (input) side of the IntelliFlo relay.

So the intelliflow would go left of the "Aux Relay Port" on your diagram above, and the "Aux Relay Port" is the SPDT relay you mention?

Would this 24V transformer be suitable for a pool?
