    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...

    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...

    Mastertemp 250 - short cycling, low exhaust gas temp

    My Mastertemp 250 was installed in the fall of 2016, and is on it's 6th swimming season. Last year I replaced the SFS, the Thermal Regulator, and the ignitor (mostly in part to the heater short cycling and the breaker tripping, two different issues that I had during the year). This year after...

    Intellicenter Automation and SR Smith Light Control

    Thanks Jon / Ron. This is basically what I thought. They're probably using a 4-wire SMD type LED setup, vs the Pentair power cycling. It is good to know however that it recalls whatever was last on, so if we do end up having to control the SR Smith lights, it'll just be set to the favorite...

    Intellicenter Automation and SR Smith Light Control

    Is there any interoperability between the Pentair lights / automation systems, and the SR Smith lights? Basically I'm trying to determine if the SR smith lights function the same way as the Pentair lights. Can the Intellicenter change the SR Smith light colors, or do the SR Smith lights...

    Can anyone identify this trim cap?

    I tried Inyo pools again, and they still haven't been able to come up with anything. Here's to hoping someone on here can either identify the ladder or the channel to point us in the right direction. Here's a picture of the ladder and a picture of the channel. Ladder: Side with all trim...

    Can anyone identify this trim cap?

    Same here. Every time someone comes over, it falls out, and then a kid will walk up to me and say "I found this in the bottom of the pool. Do you need this?". If it's not a kid, then I find it when I clean out the filters on the robot. I figure it's probably a $3 part, so I should just order...

    Can anyone identify this trim cap?

    That's actually where I started before I posted the thread, and over chat they didn't seem to have any idea what I was talking about. Maybe I need to send them a picture. Did you find a replacement for yours?

    Identifying leak in wall of ig liner

    There are less time consuming ways, but you need equipment to do it. Leaktronics makes some equipment that can do this but it's not cheap. You could go on the leaktronics website and use their map to see who in your area has bought equipment and try to find someone that has the electronics. If...

    Can anyone identify this trim cap?

    We have a steel-walled, vinyl-lined inground pool, with a recessed ladder in the deep end. The ladder has trim going up both sides (that I assume cover the screws that hold it into the wall). At the top of the trim, there's a little white cap, and the prongs that hold the cap into the trim...

    Intellichem - and yup orp issue

    The new probe ORP seems to be closer to being in line with what I'd expect - it's measuring in the upper 600s and the mid 700s over the course of the last two weeks which is what it should read given my FC numbers. There's no way to generate alerts with the Intellichem out of the box. It's...

    Intellichem - and yup orp issue

    So a little more to add to this thread. Last week was the perfect storm. We were out of town, and 3 days after leaving, the ORP sensor decided that it was going on vacation too. It started reporting an insanely low level (the ORP mV reading was in the 100s and 200s, but the history on the...

    Intellichem - and yup orp issue

    dradam - thanks for chiming in. I log my additions too, and I've been adding trichlor pucks here and there since the start of my logging, and unforunately, the addition of the pucks doesn't seem to correlate at all with the pucks being in the skimmers (in fact, right now, I have a trichlor puck...

    Intellichem - and yup orp issue

    The funny (maybe not funny?) thing about the ORP system is that if you can "catch" the swings, and reset your setpoint before it overchlorinates (or you're left with zero FC causing an outbreak), it'll hold it's value for weeks / months and self-maintain. To me, the biggest problem is that I...

    Intellichem - and yup orp issue

    The ORP function is finicky. I went down this path after reading all of the threads that said it was finicky, with the mindset that there must be a way to do it if you keep everything perfect enough. That hasn't proven to be the case. I'm very type A, and I've kept everything as close to a...

    Intellichem - and yup orp issue

    Correct, still trying to hold CYA at ~ 30 ppm. I have had an additional ORP probe on order for about 3 weeks now - back from when ORP values were in the 400's, I didn't have much for choices, as the IntelliChem has a low limit of 400. So if it's reading 390ppm, the Intellichem will just keep...

    Intellichem - and yup orp issue

    Sharing this for anyone interested, or for anyone that can explain this. This is where I really struggle to trust this. Our pool is covered whenever it's not being used, which is 99% of the time. Last week, it statistically was open about 7% (12 hours out of 168). So earlier in this thread...

    IntelliConnect Review

    This is in the IntelliConnect manual, so according to Pentair, it sounds like you only need the RS485 connection, and the IntelliConnect uses the IntelliFlo status to Enable / Disable the SWG, not relying on the SWG flow switch: "When an IntelliChlor or iChlor SCG is wired to IntelliConnect via...

    Intellichem - and yup orp issue

    No, the pump has been running 24x7 since we started back in April. For the skimmer fix, I had just turned off one skimmer suction line - the pool was still pulling from the main drains and the other skimmer. The lines for the intellichem are fed from the main lines that run through the filter...

    Intellichem - and yup orp issue

    So I cleaned my ORP sensor, and tested my FC. Pre-cleaning, ORP was reading 518. Post-cleaning, it's reading 501. FC is currently at 7, and pH is at 7.62. To me, it's unexplainable, unless there's some kind of an equipment malfunction...

    Intellichem - and yup orp issue

    I'm not sure if it's related to the pH, but it doesn't look so. pH has come down - currently at 7.63, and ORP has dropped to 518. Pool cover has been closed since Wednesday, pump runs 24x7 on low. As for the maximum amount per day, yes, that does exist in the intellichem settings, and I do...

    Intellichem - and yup orp issue

    Since the weather here hasn't really been warm enough to swim, I've been using this time to create a detailed log of ORP and FC levels in my pool. I was on what I thought was a very controlled environment, since the pool has basically been covered for a month. I open it up every few days to...

    Automatic pool cover housing floods

    Here's what the cover box looks like from the outside. There's a drain on both ends - inside of mine, the cap has like a grid to strain out debris. It's the round thing at the bottom that the arrow points to in this picture:
