OmniLogic Multiple Pumps + Heaters

[NotAnAd]

I just took over a new build for a company that was in desperate need of help.
They went wayyy overkill with their design.
I will attach pictures.
5 VS Pumps, 2 Heaters, 2 Filters, all stacked on top of each other and shoved in a corner with no room to work. Pool/Spa combo but they plumbed everything individually so it’s 2 bodies of water.

I need to get this all wired up to the OmniLogic board. I work with Omni frequently but it’s usually a simple set up 1 pump 1 heater. I have the comm. cables set on the pump ends, but need help with the board end.

How do I wire 5 pumps and 2 heaters to the comm. ports, or should I be using the relays?
The builder/electrician has nothing on the relays, everything is hot to breakers.

Please any help will be greatly appreciated.

@1poolman1 @wireform @Lake Placid Any of you guys setup a multiple pump Omnilogic system like this?

What do you think of the stacked heaters? Will the lower heater have a draft problem with its location?

Anyone with any experience doing this?

Lower heater will be pumping exhaust gas into the upper. That may cause combustion issues.

Use Low voltage relays for the heaters. LV1-LV4. The OmniLogic can control a ton of heaters just use some wago or wire nuts if you run out of space for the comm ports. The picture is just 2 pumps I think only 2 sets of wires will fit into the contacts.

It’s 5 pumps,

2 on top and 3 on bottom.
Pool Pump, Spa Pump,
Jet Pump, Jet Pump, Waterfall Pump

What about how there is 2 water sensors?
One for each body of water.
Does the board have spots for 2 sets of sensors?

I found it. It has the capability of doing 2 different water sensors.

 

[ChrisABS]

It’s says DE Spa or something similar for spa water temp sensor. The should be at least 2 comm connections for pumps and other equipment that has an HUA(Hayward unique address). You will just have to wire nut them together and run a jumper off of that to the connector on the board because the connector can only fit 2 sets of 18 gauge wire. I suggest open the pump panel and write down the HUA of each pump so you know what it what while you are programming.

Here is how you would wire nut or wago clip in all the pumps

Thank you so much for the help.

I am still understanding this stuff, but how could the system turn on just one of the pumps if they are all tied into the same comm. port like in that picture?

Wouldn’t everything that’s on that port turn on at once?

Each pump has a unique address - the HUA.

The Omni system puts messages on the comm port with the HUA and only the pump with that HUA responds and the others ignore the message.

Okay makes sense.
Thank you.

So I will program that hua in during the configuration?

See what Chris suggested above.

I think the Configuration Wizard gives you a list of HUAs it finds on the system for you to choose.

 

[ChrisABS]

The HUA is inside the pump control panel on the metal divider that separates power and control sections.

Someone mentioned that the air blowers being right by the heater exhaust is going to blow fumes into the spa? Ever hear of anything like that?

 

[ChrisABS]

Yes keep gas heaters away from forced air inlets.

 

[ChrisABS]

It makes it really tough working after someone. You have a doozy on your hands. They could have eliminated at least 2 pumps by using a diverter valve and an actuator on a bigger pump.

 

[ChrisABS]

Here’s an example of a similar build with pool, water features and a spa. We bought a larger pump with 3” inlet outlet and ran a diverter valve on actuator. I tested and ran system on 50% (forgot actual rpm’s) but the heater still ran and the water features were working.

Next big obstacle will be winterizing this thing.
I’m in New Jersey.

Since everything is variable speed , it is possible to not close it and use freeze protect correct?

But how does it work for the air blowers that have water sitting in the line not moving?
