    New Zodiac TRi Ph too good!

    Hi,

    I replaced an ageing SWG with a Zodiac TRi Ph which I am pretty happy with, I got the large model, the problem is it's too good.

    It's summer here and with the timer set to 4 hours and the SWG output set to 60% the Ch level is creeping up.

    The solution I was thinking of would be to run the pump for 4 hours but only have the SWG running for maybe 2.5 hours at 100% output but the timers only control on/off they don't seem to allow you to change the preset output level.

    I don't have any external panels or controllers.

    Do you think I could get away with running the pump for only 3hrs a day with the SWG at 100%, my slightly educated guess would be that my 1hp pump would probably filter around a third of the pool volume in that time.

    I am thinking energy saving at the end of the day but if it would mess up the pool...

    Cheers
    Richard

    Why not just run the swg at a lower setting at the same run time?

    3 hours at 100% would be the same FC production as 4 hours at 75% ... so that would actually raise your FC higher than what you are currently doing.

    I agree with Dave, why not lower the SWG output to 40% or so with the 4 hour run time and see how that works?

    Thanks!

    I was trying to save on wear and tear of the cell, it should theoretically last longer if it's 100% for a couple of hours?

    Have you read this...

    Just read it, maybe I might try an hour in the morning and an hour in the afternoon at 100% and see how it goes...

    As I understand it, the percentage setting is an on/off duty cycle, not running the cell at "60% power". The life of the cell is generally dictated by how much chlorine it produces, so it would not shorten the cell life.

    Ah of course linen, thanks for that, so essentially the new chlorinators are SMPS (the old one was a transformer), so 50% output would mean that the cell would only actually be powered half the time, using half the power!

    Re: New Zodiac TRi Ph too good!

    That is the way I understand it too ...

    2 hours at 100% would be the same "wear" as 4 hours at 50% or 8 hours at 25%.

    Figure out how much you need to run the pump to keep the water clean to your liking and then set the SWG to whatever % is required to maintain adequate FC.

    Thanks all, I have set it to 4hrs at 50%, that should be about right, I will monitor it every couple of days with my Taylor DPD kit.

    Do you have only the DPD or the recommended FAS-DPD?

    What are your CYA and FC levels currently?

    Rthorntn,
    I have the zodiac tri myself and was considering upgrading to he PH model. How has that been working for you so far? I have heard a lot of bad reviews about the acid injection on those but I would make my life a lot easier
