• Relay output testing
Selection of a setting from relay testing closes the corresponding relay and therefore switches on
the connected component. This makes it possible to check that the relays are in working order and
that the wiring has been performed correctly.
This consists of instructing the regulator's relays one by one and checking their outputs. This en-
ables you to check that the relays are working and that the cabling is correct. Check that each ap-
pliance in the installation is operating correctly.

The display shows the "Key" symbol. Pressing the Info key displays "Error 368".
WARNING
• The component being tested is receiving electr.
• During testing of an output, the heat pump is stopped, all outputs are "off" and only the con-
trolled output is on.
• Analog input/output testing
– Cooling mode DO2: Shows the output status.
– Output test UX3: Enables testing the outdoor unit control.
