Description
Displayed value is a checksum:
Check = Checksum refers to a current consumption value
M-Check = Checksum applies to a saved yearly
or monthly value
Current flow available
No energy metering -> No temperature difference

Processor
The meter's processor is designed as follows:
1

1 LCD 5 Interface cover
2 Button to change between levels 6 Module interface
3 Button to navigate on a level 7 Fixing holes for external add-on
modules
4 IrDA interface 8 User protection and sockets for external
cable connections
The processor's ambient temperature cannot exceed 55 °C. Avoid exposure to direct
sunlight.
Depending on the version (compact or removable meter), the processor can be removed
from the flow measuring section to be fitted on the wall with the mounting bracket at a
distance of 40 cm.
Add-on modules
The external add-on module (WFZ..) can be fitted to any meter.
Proceed as follows:
● a) Remove the interface cover from the heat meter
● b) Plug in the add-on module and secure it
Shortly after fitting, the add-on module identifies automatically the type of meter and makes
the required alignment (series number, monthly values, due day, current value and type of
medium).
