SunTouch two solar valves

[Sticky]

Hi

I have to rejig my plumbing to get the VRV to stay closed by getting more pressure on the return side .

I should be able to put a valve on the return solar pipe before it goes to the normal pool returns BUT.....

I have notice that the deep reurn in solar mode is not working , when I block one of the surface returns air will start coming from the deep return .

So I wish to put a two way actuated valve at the spot shown to direct all the water to the deep end . This valve will operated with the solar valve .

This give me enough pressure to close the VRV direct warm water to the bottom where its coldest and when solar is not on the VF intelliflo will still have it full flow .

I want to do this in solar only mode , I have a intellicom2 to operate the VF on external control so I use the VF menu instead of scrolling thru the Suntouch menu .

Can this be done / can I use Valve A or B in Solar only mode .

Can I get valve A or B to activate in Solar only mode when solar comes on.

OR

use AUX 1 relay for the booster pump to activate a actuator controller when the solar comes on.

or use the pool/spa mode and give up the intellicom2 ????

There must be a way to do this.

or I might need a new controller.

You could wire two actuators off of the one Solar connection.

I would not put the load of both actuators on the Suntouch circuit board (Motherboard), but rather have the "Solar connection operate a relay which controls the two actuators attached to the original Suntouch 24VAC transformer wires.

I can combine these two drawing with the proper connection if you can not visualize it.

Hi Jerry
So the red/white from the transformer would go to the relay . The black from the two actuators would connect to the black from the solar terminal .
and the 4 others to the relay .
The reds from both actuators would connect to the same pin on the relay
same with the white ?? .
After reading a few different threads here on TFPs I had given up on configuring the ST and was thinking along your lines . I thought it would be more complex but .

A wiring diagram would be great if it's not to much . The 24vac relay would need how many poles ? .

Here you go

You only need one of the power wires from the solar connector. With a voltmeter, you want the wire which is not normally powered, either the Red or White.

You don't want the VRV on the return side. Please read this.

Also, you should keep your posts together for history.

Mas I will reply in that thread , I wanted a new thread because this is a different problem needing electrical expertise .

Jerry I can not buy that relay in Australia cheapest I can find with shipping is $112.00 .

I have found this http://australia.rs-online.com/web/p/non-latching-relays/6138072/ is it an equivalent or could you find one that is please . http://australia.rs-online.com/web/c/relays/general-purpose-relays/ .

I don't understand why we cant buy such a simple thing here .

Any 24VAC 2amp DPDT relay will work, normally the type depends on the space inside the enclosure (Small relay) or on a relay which has the ablilty to be mounted externally like the RIB2401D

You only need one of the power wires from the solar connector. With a voltmeter, you want the wire which is not normally powered, either the Red or White.

So at the moment the red wire to the actuator is the powered wire , I have the intellicom2 connected to it . So the white wire would go to the relay ? and cap the red ? .

 

[Sticky]

Also would the relay in the first link do it plugs into a board to attach the wires to .

 

[jerryt]

Red or white does not matter, you can reverse the logic at the actuator.

The relay with base is fine as long as it is DPDT.

Jerry you have been so much help thanks !!!!! just one more question

Ive ordered the relay and attached a pic of its wiring pin layout , do I have the N/C, N/O , and Comm in the right place ? .

 

[jerryt]

You are owning it, and appear to understand the schematic well.
N/C, N/O, Comm, and 24VAC coil are correctly illustrated.

All thanks to you Jerry , once this is done I will look at the firmware issue .

Just saw this question. I meant cap unused wires. If the red wire is used for the Intellicom2, you don't need to cap it.

Sticky, how did this work out for you?

 

[Sticky]

It all worked out well , I have only just wired it up and it all works fine relay and second valve wise . thanks to Jerryt

Iam running solar at 27gpm and may get it a bit lower as the specs for the panels for optimum heat exchange say 4-5gpm per panel , there are three panels .

I may even add another panel it would heat the pool quicker and bring the needed flow rate up to 20gpm .
