Domestic water metering inlet: hydraulic connector 

ESC1 (G 3/4”

)

Domestic water metering outlet: hydraulic connector 

USC (G 3/4”)

(The USC connector is called 

ESC2

 in the template casing)

A meter kit for measuring water consumption is available as an accessory.

t %PNFTUJDXBUFSNFUFS,*5GPSNPEFMT3"o3";

The kit comprises a

 SIEMENS WFH36 

electronic volumetric meter with display and radio data transmission (featuring 

the same characteristics as the heat meter: see §18) and two connection pipes housed inside the frame of the user 
module in the holes made for that purpose.
