Jandy varible speed pump
Comments (11)Any pump will work with Jandy automation. If it's working fine now, there would be no reason to swap out three years of remaining warranty. Yes, you will save on energy but that cost could very well be wiped out by suddenly going out of warranty on the Jandy stuff. But, once installed, a variable speed pump will begin saving which is not what you are doing now. My personal opinion is that the 5 year deal they give is because people are more likely to swap out to other items as the Jandy stuff fails. On after market, Jandy is highly expensive to supply parts for compared to other lines and you will usually have to wait for those parts. The filters are more expensive but deliver no more performance than any other line. The pumps are inferior to what is currently available but they have one of the better heaters and their automation is the simplest to run. I only say make those statements as you ask what an exchange value is. For a homeowner, I guess the market would have to be tested. For a contractor, there is no reasonable reason to purchase a used piece of equipment so the value is almost zero on that side. Once in awhile, you'll have a need for an Aqualink board and it could be worth up to $400 to a contractor who has toasted one for some crazy reason....See MoreIntelliflo vs 2-speed for pump replacement
Comments (3)hajbo- Good question and this is going to be mostly a personal preference. You're obviously doing your homework and have read this forum and others. The variable speed pump at low speed will be marginally better than the 2 speed at low speed. As you mention, the variable speed does require a circuit board (actually a high current wave chopper, as they're know in the motor industry) to operate. If the circuit board (drive) fails, then the pump will not work. Not sure what Pentair's policy is regarding replacement drives. In HVAC, there are some manufacturers that replace the drives and others that require a full motor/drive combo replacement. From my experience with variable speed technology in HVAC, I personally decided to go with 2 speed technology. Both of my 2 speeds were put into service in 2007 and no problems to report. I would get a quote for a 2 speed installed plus rebates and compare to a quote for a variable speed plus rebates and then calculate how much money you will save annually with the variable speed assuming 300W/hour difference to see how long you're payoff will be and also look at manufacturer's warranties to help with your decision. Example, if you plan to run the pump at low speed for 8 hours per day, the daily savings with a variable speed will be 8 hours x 300 watts = 2,400 watt-hours. Multiply the 2,400 watt-hours by your utility rate to determine daily savings...so if your utility rate is $.30/KWH (you said SoCal so this is a guess), then your daily savings with variable speed will be $.72 per day (not too bad) and the payoff will likely be less than 2 years, assuming no failures or drive replacements. For me, at $.07/KWH, it would have taken over 10 years to recover my investment for variable speed technology. From my experience, relying on any high speed rotation equipment to last more than 10 years is a risky assumption regardless of variable speed or 2 speed technology. As you said, it will obviously be more expensive to get the variable speed technology working again when problems occur. It's a personal preference but wanted to share my logic....you're mileage may vary as they say. Hope this helps! Tres - Welcome back....missed you on the boards the last 6 months! Hope all is well....See MoreTwo Speed Pump Operation?
Comments (4)Filter is a DE 60 so I am concerned about the current 24 hour run time. We have a very basic generic timer for now. So I need to figure out how I can do an off cycle without having to manually flip the switch off. (again my ignorance is showing!) Leonard, I'll have you know that your build was inspirational for mine. I'll post a pic if I can figure it out. Does it make a difference in your pool the time of day the pump runs hi/low? With SWG does the chlorine level vary during the day as well?...See MoreIntelliflow with Jandy Control??? Possible? Have Other Issues..
Comments (8)The IntelliFlo will communicate directly through the RS485 cable to an IntelliTouch. Any other system requires the IntelliCom which is an interface that communicates through a function on the pump called EXTERNAL CONTROL. EX CONTROL basically takes any electric signal and activates a preprogrammed function 1-4 on the pump. Thus, 4 speeds. With the 3.2kw, you still get all the additional features it offers but it works with the 4x160 as well. The common installations require one AUX relay for each of the 4 speeds you set up. So, if you buy an RS8, you have wiped out 4 right there. If you can wait a year, sure, Jandy will allow the pump to plug directly into their new board. You may consider the Pentair Easy Touch as it will not require the IntelliCom. Techs do have the ability to tweak installations on the IntelliFlos with Jandy as there are other places to hook into that do not use a relay. You basically need any DC output that can be controlled from the panel sockets. Valves are all the same and will work on any system. The Jandy valve is far better from a set up standpoint if you need to adjust them but they come at a price premium over others. The IntelliTouch is not dated. It is a great system that is probably one of the best out there. You may consider a Jandy PureLink that will give you automation and salt. The new LXi is an awesome heater. I'd take it over the Pentair anyday....See Moretrhought
