There are three different models that you can get.Dual Equipment: Pool and Spa with Dual Sets of Equipment – The IntelliCenter control system i10D (P/N 521915) is designed to operate two sets of pool equipment. Each set of a equipment (Pool or Spa) can control one temperature setting. This IntelliCenter control system Personality Kit can control up to 10 pumps and/or lighting circuits, plus two heater circuits. The Personality Kit includes, eight auxiliary circuits plus two filter pumps. Five relays are included in the personality kit and five in the Load Center.
7,Jim, that’s really impressive. Can you recommend a relay?
For the 240 VAC relay I just used a spare EasyTouch relay that I already had. Just mounted it inside the Spa and ran the low voltage coil wire back to the ET.
For the temp probe relay, I used a Pentair 2-speed pump relay, but again only because I had it for another project that I never did do.. Any cheap Single Pole Double Throw (SPDT) relay with a 24 VDC coil will work just fine for the temp probe relay. You would just need to find some place to mount it in your IntelliCenter.
To follow up on what JamesW said above.. I have the Pool and Spa EasyTouch... But, because I do not have an in-ground spa, changing to the spa mode has little effect on my overall operation.. The pool pump still runs, the skimmers still skim, etc. For all practical purposes the pool itself does not know the ET is in the spa mode.
Since the hot tub will come with a relay that powers the hot tub heater element, you might be able to just use the heater control in the Intellicenter to make or break one leg of the relay coil voltage.
Since you would have a pool heater and a spa heater, you should probably get the dual equipment model if you wanted to control both and heat both at the same time.
Single Equipment: Pool Only or Spa Only – This system is designed to operate a single body of water (LO-TEMP and HI-TEMP). The Personality Kit models are:
i5P (P/N 521909) – Four auxiliary circuits plus filter pump operation. Five relays are included in the Load Center.
i8P (P/N 521910) – Seven auxiliary circuits plus filter pump operation. Three relays are included in the personality kit and five in the Load Center.
i10D (P/N 521911) – Nine auxiliary circuits plus filter pump operation. Five relays are included in the personality kit and five in the Load Center.
So, it depends on how many auxiliary circuits and relays you want.
