    Raypak Versa 405B thermostat wiring diagram?

    I think I have the thermostat board bypassed and it works great. Good thing, those replacement boards are like $500.. Attached is a picture of what I did. The now bypassed thermostat board is in the top left. 1) Attached transformer 24V directly to 24V on ignition box 2) Attached thermostat...

    Raypak Versa 405B thermostat wiring diagram?

    Found the diagram.. Thanks TroubleFree Pool. Need to search for 5m longer before posting. That said, any tips on just bypassing this? Can I come out of my pressure switch, through the hi-limits, and drop to ignition ground? That would bypass the board entirely, but keep the safeties in place...

    Raypak Versa 405B thermostat wiring diagram?

    My system is still running this ancient heater from 1987. Physically, the thing is bulletproof, however, we recently had a power fluctuation (main panel lost a leg and the heater system is 240) and it stopped switching on. I've debugged each component and done some maintenance. Replaced the...

    Pentair Intellitouch Airswitch

    Signature updated, sorry about that. I recently upgraded my Compool to Intellitouch. The air switch currently switches 110V, it was used for the old pump so I will need a new one for sure. Thanks for the diagram, that makes a ton of sense, I had not thought about the IS4 connection, very cool...

    Pentair Intellitouch Airswitch

    Just upgraded my Compool to Intellitouch and it went great but now I need to sort out my air switch. Previously the air switch in the spa directly controlled an old dumb pump that ran at a single speed. I replaced my spa pump with an Intelliflow VSF which means it is controlled over RS-485...

    Spa pump backwashes when primary pump is off

    Thanks for this, it matches a lot of what I had in my head. 1. That was my initial thinking, I just was not sure if it was accepted practice or not. Sounds like it is.. But I think its probably better to just update my automation. There is a lot to be said for fixing all my problems at once...

    Spa pump backwashes when primary pump is off

    Here is my LX-10 open. I agree, its time to upgrade this thing. I already purchased replacement relays for the existing relays that are dead (primarily the pool relay) so I think the upgrade kit just replaces the left side of the box (the logic) and that logic controls the existing right side of...

    Spa pump backwashes when primary pump is off

    Great catch @guinness , it is the 011056. Currently, it just runs the built-in keypad using the 8 programs and is direct wired, no relay control. The pool pumps had bypassed the control system and had been wired to a mechanical timer prior to my ownership. Since it was a single-speed pump + the...

    Spa pump backwashes when primary pump is off

    I am using a latest generation Intelliflow VSF, just not automating it. I've had that upgrade kit on my list of things to buy, the only thing holding me back is that I don't think it works with my existing Compool head-end, I'd need to replace it with the EasyTouch panel and wireless kit and I...

    Spa pump backwashes when primary pump is off

    Here is a picture, the plumbing eludes me on this as the spa pump (black pump on the left) is only piped to the spa which means it must be pushing pressure back through the spa intake and somehow causing this? Unless its Tee'd to the filter underground and if thats the case my brain broke a little.

    Spa pump backwashes when primary pump is off

    I am mechanically competent and starting to learn my pool in our new home. When I took it over it was a circa 1985 dumb pool using pentair and compool equipment. Since taking it over I have replaced the single-speed primary pump with an Intelliflow VSF, rebuilt my spa pump with a rebuild kit...
