Just joined the forum after purchasing a house with an existing in ground swimming pool and spa. I doing some research on my pool equipment. Current controller is Aqua Logic PS-4, cartridge filter, Pentair Variable Speed pump for pool and spa, Pentair Salt generator cell. What I don't like is currently the VSD pump operates off it's internal time clock, set for 12 hours [starting at 9pm] with the first 3 hours at high speed and the remainder at low speed. The Salt cell is run off relay the filter relay starting at 9:15 pm through 6:15 am but is based on the Aqua logic internal clock. My first concern is with a power failure and the 2 different clocks not being in synchronized the salt cell could be active without flow.
Current relays are:
Filter to Salt Cell
Light for Pool light
Aux 1 for Spa light
Aux 2 for Spa air motor
My desire is as the Aqua Logic can drive the VSD pump by serial connection so using a Pump Link Translator sold on Ebay for $60. I question whether the internal timers will permit operating the pump as before, however that would have Filter relay set for 3 hours = high speed and re-purpose Aux 1 for low speed for remaining time but setting the Salt cell becomes an issue.
Any suggestions appreciated.
