Solar thermal electric ball that disjuncts?

[Christophe]

A thermowell is a tight hole!

For wiring it is not very complicated: you open the existing adjustment box, you spot the resistance wires (regulation output) and you transfer them to the new regulation (in 2,5mm2, 3G2.5 so ...)

But before simply lower the set point and observe what is happening!

It may just be an overheating in the case ... 40 ° C is enough for showering!

Put some pictures too!

Whether you set the temperature to 30 ° or 70 °, it's the same. Sometimes it jumps, sometimes not. Today, it only jumped once. Yesterday 5 or 6!

Take off the hood and take a picture of what is jumping ...

I'll do this tomorrow. It is a small encapsulated module. Thank you!

9 chances out of 10 that it is a thermal (which may be messing around) ... € 3 to change ...

With a little hope, I will be able to find the part (of better quality?) To change.

Guygadebois: "You have to press a small button located in the resistance box."

Christophe: "you can shift the regulation into another glove finger .... your balloon must have one"

It's getting hot, this case!

Probably the 90 ° limiter which is defective or out of adjustment.
A resistor with integrated mechanical thermostat like this https://france-chauffage-solaire.fr/pie ... cs-39.html can be tested disassembled if the thermometer is working well or another thermostat in good condition.

If you disassemble to descale, it is better to have a spare gasket.
