    IntelliCenter with multiple ETI Heaters

    This is listed on the datasheet for that relay - would I be incorrect to assume that these specs are for when the coil is energized?

    IntelliCenter with multiple ETI Heaters

    OK, so in other words, add something like a RIB double throw relay, the J2 will tell the external relay to close, and the external relay will switch both fireman switches independently at the same time. I'm guessing that depending on the relay, a person could use the 24v coming off of the...

    IntelliCenter with multiple ETI Heaters

    So are they saying to route this wire into the high voltage area of the box, and use those relays to activate it, or is there a better way to do this? I was also thinking that since one of the sides of the fireman's switch is effectively going to have voltage (aka, be "hot"), only one...

    IntelliCenter with multiple ETI Heaters

    So I was reading the installation manual on the ETI 400 heater, and it states that you can install multiple heaters in parallel: The question that I have is about control via the IntelliCenter. It doesn't look like the ETI 400 heater has an RS485 connection, so it would have to be the...

    Pentair Serial COM Port Expansion Board Installation

    @MyAZPool - I know this is an old thread, but I'm looking to have an intellicenter further away from the equipment - equipment is at the rear of the yard, and we don't have a great location to mount the load center (and don't want to built a wall out there to mount it to). There's 3 valves, a...

    Aiper Seagull Pro Review

    How deep is the deep end? My pool is 20x40 rectangle with an 8' deep end, so I'm guessing I'd have similar results....

    Aiper Seagull Pro Review

    How well does this track lines? That's one of the annoying things that bothers my type-a personality with the dolphin units, which is amplified even more when it starts going in circles and wrapping up the cord. I watch the robot going at something that needs to be cleaned, and it seems like...

    Polaris Freedom?

    Yeah, I'm kind of in the same boat - I think I'd give wireless a whirl and see what happens. My Quantum was on the struggle bus at the end of the season last year. The cord needs to be replaced, it's starting to do the peeling thing from being left in the water 24x7, and the suction seems week...

    Polaris Freedom?

    For some reason I thought that Polaris and Dolphin are basically variations of the same thing with different labels on them (like rebranded with a few differences to make them different to the consumer), so I'm not surprised that they release at the same time. Thinking about trading in the...

    Mastertemp 250 - short cycling, low exhaust gas temp

    The video makes sense. The part that I wasn't understanding is how to test line pressure vs what the heater is consuming, but hooking the nanometer up and then letting it cycle and watching for drop makes sense. One other observation that I'll throw out there - the heater exhaust not only...

    Mastertemp 250 - short cycling, low exhaust gas temp

    OK, so I pulled it apart again. Here's some pictures from the manifold in case something looks out-of-whack. It all looks good to me. The bypass valve moves freely, etc. Here's a video of the water flowing through the manifold, seems to move freely to me: 20220529_132941.mp4

    Mastertemp 250 - short cycling, low exhaust gas temp

    The manifold all looked good (outside what I washed out of there, which I'm assuming is copper from something), and so did the bypass valve. I didn't think to flow water through the coils. I'll disassemble it again and do that to double check. @JamesW - Gas Pressure is something that I wanted...

    Mastertemp 250 - short cycling, low exhaust gas temp

    Thanks @ajw22 . Just pulled it off, and there was definitely some copper in there. Not sure where this came from as the ends of the heat exchanger were all still in tact. I put it back together, and it's still short cycling, and the exhaust temp is low both by the display (120 - 150F) and by...
