Connecting Vaillant vr940f (internet gateway) to SensoComfort

[AlanB1976]

Hi all
Recently had a Aerotherm Plus heat pump and cylinder installed. It includes the Sensocomfort and I was surprised to see that something of this day and age doesn't include remote access as standard. Anyway, I went and purchased the internet gateway (vr940f) to connect up. It comes as standard with the plug in point for the boiler which I don't obviously have. Am I right in assuming that I just need to ensure power to the unit (still to find out voltage) by connecting a suitable power supply to the screw in terminals, and then isolate the other 2 cables from the unit and connect up to the bus port of the sensocomfort? I already have an outside sensor connected there but I believe you can have multiple connections through the ebus terminal
Thanks

Yes, it needs a separate power supply.

(still to find out voltage)

From the manual, it can accept a power supply from 5 to 24V DC, centre positive...

In some countries, a PSU is included in the box (worth double checking!).
The included PSU is a 5V, 1A supply...

by connecting a suitable power supply to the screw in terminals,

It should have its own power jack socket; the screw terminals are for the eBUS connection.

but I believe you can have multiple connections through the ebus terminal

Yes, it should be possible to daisy-chain onto the Vaillant eBUS.
