How to check if OTGW properly assembled?

[Bororo]

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.

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:
