Breezair Evap Control Dead - Arduino The Answer?

The snakes at Seeley have a chip in the controller box that nukes itself if something is wrong.

They attach a large heatsink to a tiny triac. So the tracks to the triac cracked, and the evap is toast.

It has a new motor, pads and water pump. But is now useless

Anyone know an easy way to make 240v fan motor spin (2 speeds would be nice. Flat out and slow), and also a water pump to spin?

This thing also has a dump valve that purges every 3 days.

So was wondering if an arduino or similar is the answer.

Any help would be great before it gets too hot!

Thanks

    Have you tried this one simple trick? Sync the remote

      Thanks, but mine has no communications due to the self destruct code built into the logic chip.
      Only this model Breezair has it (as it was a dumb / dodgey idea), and only Seeley has the code to reflash it. But no longer interested as they want you to buy a whole new unit.
      Some have talked about reverse engineering the code/ chip. But that is above my brain grade!

        It is worth looking/requesting for a second hand unit on the marketplaces and using that board?

          Yeah, been looking for a few months for exactly that. Still hoping i'll find one. But summer is approaching..looking at a plan B.

    Consider a smart relay and IDEC FT1A or similar. Not sure the number of I/O you need. You could go the Arduino route however a proper device (smart relay or low end PLC) may save on hassle. Or just use relays if you have the space. For the single phase speed control of an induction motor you need to find a suitable phase controller I think.

      Cheers. I got given an older board that i believe has a basic speed controller . But no idea how to control it / integrate it. Might have been hard wired/ physical analog dial back then. Not sure.

    You say:

    They attach a large heatsink to a tiny triac. So the tracks to the triac cracked

    and

    due to the self destruct code built into the logic chip

    So, is the problem that the tracks have broken (which sounds like an easy repair), or that there is a "self destruct code" built in to the controller chip, which sounds somewhat fanciful.

    Both. I have now repaired the tracks (and replaced the triac etc), which is a straight forward repair..BUT

    Seeley have included a chip that detects incorrect feedback, then goes into fail mode.

    Forces you to take it to Seeley for repair and only they have the code to reflash the chip. But they don't care about that model anymore.
