I've spent a few days researching how to replace my air switch / timer box with something remote control. Water got in the air switch line and it hasn't worked right since. I've looked for replacement breakers, maybe some contactors with wifi etc. I don't need a timer function, just on and off for my spa pump and blower. I believe they each run on a 220v 20amp circuit. The pictures below are the old box with timer and air switch, and the breakers that precede that box, which I believe is a quad plex arrangement. I'm open to replacing the breakers or the box.
I'm a novice with this stuff so any guidance you have is appreciated in advance. I actually spoke with intermatic and their rep told me they don't have any single boxes that can control 2 220v circuits, which seems insane to me since the original is an intermatic product.
Control unit is probably pretty easy to replace (timer assembly) and you could most likely upgrade to something that has more functionality, it would just be a matter of careful research to ensure you buy something good quality that doesn't leave your PII all over the place. I would replace the housing at the same time with something that's a little more built-to-last
Overall I would be more concerned with the fuses. Electrical & rust is not a good combo. If that housing is leaking, definitely address that too. If you don't know electrical, hire out on that part.
I'm not a pro, just someone with a bunch of diy experience.
Thanks. I'm comfortable doing basic wiring. If I replace the breaker box, I'll have a pro do it. But for the controller, it may seem simple, but I have yet to find a specific product or mix of products that can simply turn off and on 2 220 circuits by wi-fi radio or BT. That's what I'm trying to find.
Perhaps you should have someone look at the wiring before purchasing the unit. It may be nonstandard wiring or maybe there's a relay somewhere. That controller you have looks fairly basic.
