Hi all, I'm at a dead end so hoping there's some experts here who might be able to help.
Moved into my current home 3 years ago with solar PV and solar thermal. The Thermomax SMT-300 controller for the thermal has gone kaput and I think it needs replacing. It must be 10-15 years old now, and when powered on emits a buzzing noise just like in this video (not mine, but it shows the problem) https://www.dailymotion.com/video/x2lt3gi Until recently, my unit behaved like in the video - it would buzz if the power was cut off before seeming to fix itself after 5-10 minutes. However, it no longer fixes itself! There's no troubleshooting in the manual I found online so I'm not assuming it needs replacement. But cannot find the same part and have no leads on how to find something similar I could drop in.
With that, my options seem to be: Call up a local specialist company and pay a big wedge of money for them to supply a replacement - unless they have a very similar model I suspect they'd have to change the sensors, so with parts and half (?) a days labour I'd guess I won't see much change from £1,000
Accept that it's just not economically worthwhile replacing and leave it. (Don't know if that means it'll blow up next summer!)
Any suggestions or leads on replacement parts?
Cheers.
