Heating hysteresis sequence

I have a system with a heating pen and a minimum and maximum temp probe which runs in a time dependent study.

There is a continuous sequence of heating and cooling determined by the temperature of the system.

Heating 1: as long as the min temp is below 370°C.

Cooling 1 starts if min temp has reached 370°C
Cooling 1 runs until max temp is below 230°C

After cooling 1 Heating 2 starts until the min temp reaches 370°C

Then cooling 2 starts until max temp is below 230°C

And so on…

Is there a way to implement this in comsol (I’m dealing with two different parameters Tmin and Tmax for 1 on/off signal)
Is this possible with a function or with IF conditions (maybe nested)?
Is there an example available of such kind of controlling?
