Connecting Hayward/Goldline 235 Solar Control to Tristar W3SP3206VSP

[rogue]

Hi

My TRISTAR VSP (W3SP3206VSP) arrived yesterday for my (hopefully) "drop in" Ecostar VSP replacement

Hayward training videos and others online are for older model Tristar VSP's with different physical configurations and not helpful.

The Tristar VSP piping match to the installed ECOSTAR VSP is exact as concluded from owner's manuals specification review.

However as seen in the attached the relay connections pints are not the same. A review of the Ecostar owners manual shows clearly defined connections between the control (in my case Hayward/Goldline GL235 Solar Control) and the Ecostar VSP relay connection points. The Tristar VSP manual does not have the same drawings but cryptically states "The +12V and COM terminals may be used for low voltage supply..." In addition, the Tristar VSP manual states "Remove test leads to install."

So two questions for my "drop in" Ecostar VSP to Tristar VSP replacement project referencing the attached annotated pictures:

1. The Tristar VSP L1 and L2 connection points have two push on leads connected to each. One push on connection is clearly the black test lead to be removed. Is the other push on connection part of the test lead configuration to be removed or does it part of the final connection?
2. Is the planned GL235 to Tristar VSP relay connection plan shown with dashed lines correct?

I'd appreciate any comments/advice

Hope the pictures help another DIY with a replacement project like this.

Thanks!

Chris

Test leads are the two black wires with the bare terminal (that you may have already removed). Leave the others in place.

Hi

Many thanks for the prompt reply!

Was the relay hook up correct?

Hi

Many thanks for the prompt reply!

Was the relay hook up correct?

From what I remember about those pumps, and if it worked, yes.

Perspective much appreciated.

Hi,

Attached is the summary with annotated connection pictures of my swapping my 2012 Ecostar VSP with GL235 solar control connected by relay to a new Tristar VSP W3SP3206VSP.

High points:

1. Piping connections were a direct match
2. About 8 inches of extra bonding wire length are needed if the bonding wire runs from the strainer basket end to the rear of the pump
3. Relay connection configuration is different between the Ecostar VSP and Tristar VSP. The Ecostar VSP owner's manual provides a connection picture that clearly shows proper relay connection points. The Tristar VSP diagram is more generic and requires some interpretation as shown in the attached.
4. The final wiring connections shown reveals the INP1 relay connection points are DC polarity specific. This was determined during installation when the relay wouldn't work until I reversed the INP1 wires to their final locations. A close look at the Tristar VSP owner's manual diagram with added current "+" and "-" signs also reveals that the final connection locations are correct. In any event the relay works perfectly!

Hope the attached and this summary help anyone else contemplating a pool pump change from Ecostar VSP to the Tristar VSP

Best,

Chris
