and output tests. With these tests, the controller’s inputs and outputs can be checked.
To make the tests, switch to menu "Input / output test" and go through all available
setting lines.
If faults occurred during the tests, please refer to the descriptions "Diagnostics of heat
and refrigeration sources" and "Diagnostics of consumers" in this User Manual.
