During commissioning, it may be convenient to check that the connections of analogue and digital outputs are connected as shown in the scheme. But it is known that very often probes are missing, dry contacts are missing, and therefore the system cannot actually be started.

Therefore, “blank” tests are carried out by forcing the outputs and bypassing the logics.

The Zones, Circuits, Dehumidifiers, Sources and DHW pages have the possibility of manually forcing the outputs. However, it is not possible to force the Solar/Electric and Opentherm page.

Within the Circuits, Dehumidifiers and Sources pages there is a section called Manual Override:

While the Zones page in the Configuration Zone/1 subpage has a Force column that can activate the Zone output:

Warning

Not to be confused with the zone Working Mode Forcing, which is explained in ​

.

The DHW Page also has an Output Forcing line, which is different from the DHW Subsystem Working Mode Forcing:

Warning

Once you have finished testing and checked that the electrical connections are made as shown in the diagram, remember to click on Remove Force buttons, so that all the outputs return to Automatic. 

Forgetting the manual forcings entered may result in CATASTROPHIC CONSEQUENCES!!!
