Maximum Heating Time?

In the discussion, First Build: Which Heater to choose?, there is a mention of “maximum heating time to my software to prevent it from shutting down”. Is this a parameter that can be configured in the software.

I am having a problems with the Lasko #100 heater,

Even trying to maintain 75 degrees the unit will eventually stop running and requires the heater to be unplugged for 5 minutes before starting again.

Can you share your chart with the fridge lines enabled?

I do think the power of that heater is a bit on the high side.
Does it have an internal thermostat to prevent overheating?
