[QUOTE="jamestalmage, post: 223, member: 59"] Seems to me the laundry list of requests here is unlikely to fit on a single board. I think it might be most helpful if we prioritized what we want, in order from "most needed" to "least needed". Here's my best stab at it, trying to be practical. [B]Step 1 - Single Body / No features / No Chem Monitoring[/B] [LIST] [*]24VAC/DC Power input [*]Isolated RS-485 [*]2x relays (Fireman's switch and Pump/Chlorinator). Single Throw. Normally Open. One of the two should have enough protection to drive an external 3HP pump relay. [*]2x 10k Thermistor Input [*]1x 0-10v Input (Filter Pressure) [/LIST] [B]Step 2 - Chem Monitoring - V1[/B] [LIST] [*][I][I]Don't try to replace the Atlas Scientific White Box at this point[/I][/I] [*]Add One contact closure input for a flow-cell flow switch [/LIST] [B]Step 3 - 2nd Body[/B] [LIST] [*]Add another 10k Thermistor input [*]Add 2x more relays for valves. These should be double throw with both NO/NC contacts. [*]Optionally, put the relays on JST-XH connectors [URL='https://github.com/tagyoureit/nodejs-poolController/wiki/DIY-Standalone-Nixie-Pool-Controller#automated-valves']as described here[/URL], and prewire to a 24vac input per the wiring diagram. [/LIST] [B]Step 4 - Chem Monitoring - V2[/B] [LIST] [*]Now actually try to replace the Atlas Scientific Whitebox. [LIST] [*]2x Isolated EZO circuits (ph and ORP) [*]1x Non Isolated EZO circuit (RTD) [/LIST] [*]If possible an isolated i2c header that's compatible with the EZO-HUM (can replace the added 10k Thermistor I suggested with the 2nd body) [/LIST] [B]Step 5 - Bonus[/B] [LIST] [*]Additional relays for more valves [I](Should this maybe come before Step 4? The whitebox works well).[/I] [*]1x or 2x 4-20mA inputs ([I]I guess? Seems lowest priority to me)[/I] [/LIST] [I][B]Final Idea - Upgraded Fan Module[/B][/I] [LIST] [*]Pool controllers are, by definition, mounted outside. I put the Sequent fan board on my stack. I don't think there's any way to fit it on the Pool Automation board. But I think there are some upgrades that could be made that would be awesome, not just for pool controllers, but all. [LIST] [*]Add a header for an external fan (or two!). [*]Stick a 10k input (or two!) on there for monitoring enclosure temperature. [/LIST] [/LIST] Looking at my stack, steps 1-3 seem like they should be achievable [/QUOTE]
