4 5 8 Input / Output Testing Functions
Input/output testing is used to ensure that the connected
components are in working order
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

Relay test
This consists of instructing the regulator's relays one by one and checking their outputs. This enables you to check that
the relays are working and that the cabling is correct. Check that each appliance in the installation is operating correctly.
(0) No test, (1) Everything is on STOP, (2) Relay output QX1 : heat pump CC1 (Main regulation board), (3) Relay output

The display shows the "Key" symbol. Pressing the Info button displays "Error 368".
Warning: The component being tested is receiving electrical power throughout the test.

Display of 0 V means that there is no voltage and the
respective input is currently inactive Display of 230 V
means that voltage is present at the respective input so
that it is activated
