Okay thanks
so if I’m using the 0020036768 opentherm module awb. As suggested on the my boiler site.
Will the set up be
heatlink ot1 and ot2 > module > ebus interface on the boiler?
Or does it connect directly to the PCB?
So
heatlink ot1 and ot2 > module > Pcb?
Can the OTC1 & OTC2 connections on the Ultracom 1 30cxi be used to connect to the OT1 & OT2 on the google nest heat link in order to enable openthem?
The boiler engineer who fixed a few issues for me previously has installed the system but only connected the boiler using the on/off...
