4 Commissioning
To commission the units, the following steps must be carried out:
·
Prerequisite is correct mounting and correct electrical installation and, in the case of
wireless systems, correctly working radio links to all the auxiliary units
·
Make all plant-specific settings. Special attention must be paid to operating page
”Configuration“. For that purpose, the relevant operating level is to be selected as
follows:
Press the OK button on the room unit to switch to programming.
Press the Info button for at least 3 seconds and select operating level
“Commissioning“ with the setting knob. Then, press the OK button.
·
Make the functional check as described below
·
Reset the attenuated outside temperature
(operating page “Diagnostics of consumers“, operating line “Outside temp attenuated“
(operating line 8703))
To facilitate commissioning and fault tracing, the controller allows output and input tests
to be made. With these tests, the controller’s inputs and outputs can be checked. To
make the tests, select operating page “Input/output test“ and go through all available
operating lines.
The current operating state can be checked on operating page “State“.
For detailed diagnostics of the plant, check operating pages “Diagnostics heat source“
and “Diagnostics consumer”.
