Hallo,

In order to optimize the operation of a heat pump, I am using a programmable controller.
In the simulation I must also include the minimum up and down time for the heat pump. I have tried to understand this from the available templates as well as the user handbook. Can someone give me a tip on how it can be implemented?
I am trying to use 'PS' for this, but in order to see if my heat pump has run for the minimum up time, I need to get the values of several previous stages.

Thank you.

Hallo Zaideus

Check the auxiliary variable for "Prolonged time impulse" and set your conditions.
Your intentions with "PS" are correct.
It depends on your controller strategy but you might need "PI", too.

Sunny greeting
