Event interface to control ohmic heating (electric current)

Please login with a confirmed email address before reporting spam

I am modeling an ohmic heating of food and I want to add an event interface to control the heater (electric current) to stop when center temperature in the food is above 70 ͦC by 0.5 ͦC and continue when center temperature is below 70 ͦC by 0.5 ͦC. I tried to follow the steps in this blog: https://www.comsol.com/blogs/implementing-a-thermostat-with-the-events-interface/#goto-comments

However, I think I am missing something. In the example above, for the thermostat, qtot = 1[W]HeaterState. In my case, what and where should I specify such an equation?

I have attached screen for my interface and the example.

Thank you
