4 Commissioning
To commission the units, the following working steps must be carried out:
• Prerequisite is the correct mounting and correct electrical installation and, in the case
of wireless solutions, correctly working radio connections to all required 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 OK 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 OK.
• 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, switch to operating page “Input / output test“ and go through all
available setting 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”.
