Hello All,

I am operating a mushroom farm that uses steam for sterilization of substrates. I bout this 3KW sauna steam generator and it has a wall-mounted controller that has a 60 minute timer.

In order to sterilize the substrate I need it to run significantly longer than this. I am wondering what is the easiest way to wire a switch to bypass the timer completely?

Note: I wont be falling asleep while using it, just want to be able to walk away for a couple hours without it turning off.

Thanks for your help.

I'd say, no way.
There's a microcontroller in there monitoring inputs and controlling various outputs to give an ideal outcome.
Timing would be embedded in the programming and via the controller.
Bypassing anything would, I'd imagine, cause all sorts of undesirable outcomes.

When you shut the power off it resumes the cycle where it left off, so if it was 55 minutes it will be the same when I turn it back on.

As far as I can tell is that it's a heating element that is on or off, and a valve to let water in or out. The water tank is plumbed in so the valve opens when it gets to the low level on the 3 prong sensor. It closes when the water level gets to the top of the sensor. I am not sure about the various inputs and outputs.

I was wondering since the Diagram says the steamer controls has a switch which is green and yellow.

Could I supply power to that circuit using the power circuit for the led light (which I will never use)

Then I could use the switch on the remote to activate the LED circuit to disable the timer... perhaps.

The 60 minutes is most likely for safety if the steam generator is designed for a sauna. Can you post close up photos of the circuit including ICs?
