How to check if OTGW properly assembled?

Dear Friends,
is there any guideline what to check/measure on currently built OTGW?
I have no access to the boiler for the moment, so I can't connect OTGW in between boiler and thermostat, but I would like to know if OTGW is working as it should.
All I can do is to power OTGW with 220V.
Many thanks in advance.
Bororo

Hi Fabian,
thank you for mentioning this guide.
For me it's not clear if part Opentherm Interfaces measurements/checks are done with OTGW connected to boiler and thermostat, but I will check at least parts related to 220V (Power supply).
Thank you for your help.

The first line says:
If you have built the Opentherm Gateway and it doesn't work, or you are the cautious type and prefer to check the device step by step before hooking everything up


I take this to mean that the checks are done without the boiler or thermostat connected - unless you are told to connect them, e.g in Slave Interface it says:
connect your Opentherm thermostat to X1 and in Master Interface it says: Connect the Opentherm signal from the boiler to X2

That's a matter of careful reading. From the first sentence in the troubleshooting manual:
