How many relays are needed for this setup? iaqualink)

[Veccster]

I'm piecing together an iAqualink setup. Here's what I want to control:

MAIN LOOP
Jandy VS pump
Deck Jets
Stenner chlorine pump
Jandy elec heater

2ND LOOP
Jandy feature Pump
Slide
Waterfall

LIGHTING
Landscape lights
2 Pool Lights

I'll also have 3 returns on the main loop and I'm not sure if I need to control those or not???

So my question is....how many relays do I need in the Control Center? They come in 4, 6, or 8.

If using the VS pump, does each speed I want to program require a separate relay?

Took it upon myself to call Jandy and get the information needed. For anyone else who might have the same question.....

I need an RS-P6 - which comes with 6 relays and 4 valve actuator terminals. The package also includes 2 JVA's.

relay 1 - Jandy VS pump (ability to control the speed of the pump with just 1 relay)
relay 2 - Stenner chlorine pump
relay 3 - Electric heater
relay 4 - Jandy feature pump
relay 5 - landscape lights transformer
relay 6 - pool lights (wired together)

JVA 1 - water slide
JVA 2 - deck jets
JVA 3 - sheer descent waterfall
JVA 4 - empty (might use to control the returns)

So I will be totally maxing out the capability of the RS-P6 but don't see what I would add in the future to justify the RS-P8.
