Input/output assignment
The controller needs to interact with the hydronic system. For this purpose, we can feed inputs to the controller and can give outputs to the system.
To assign a variable to an input in the programmeable controller, you can use: parameterName=in1;
Following the same logic, you can provide outputs as: out1=parameterName;
Initialisation
When using a variable that has not been defined before, the controller will equal the new variable to 0. This functionality can be used for initialisation purposes with the following topology:
