Events interface - steps taken by solver

Hi,

I successfully implemented this example: https://br.comsol.com/blogs/implementing-a-thermostat-with-the-events-interface/ However, for my purposes, I just want that the HeaterState verify my condition if the time is an integer. I tried to do this in the time-dependent solver -> time stepping and I selected "steps taken by solver" as "strict" and changed the initial and maximum step to "1s". However, the solver keeps changing HeaterState at non-integer times. Can someone help me?

Thanks!
