Communication options
The WZ FW 662 can be fitted with up to two different optional communication modules.
The optional communication modules can be equipped afterwards, without damaging
the verification. The optional modules have no influence on the verified relevant part
in the cover of the integrator unit. At the latest 10 seconds after the installation, the
integrator unit recognizes the plugged in optional modules and the functions are freely
available. When connecting the communication modules, the supplied with installation
guidance is to be considered.
Parameter mode
In special cases it is possible to change the standard factory parameters. To do this the
user seal of the connecting unit has to be broken. Under the user seal is a jumper con-
nection point. As soon as the Jumper is plugged in the parameter mode activates itself. In
the parameter mode, the errors, monthly, maximum and average values can be set back.
Set days, date, time, customer number, M-bus address, analog to and pulse parameters,
functions and measuring period can are also adjustable.
Display
The integrator WZ FW 662 has the following display sequence:
• Favorite menu (if activated)
• Main menu (Billing relevant data)
• Set days
• Monthly values
• Average values
• Maximal values
• Configuration
• Service
The display levels can be customized as to the number as well as in the order of the
display sequences. For this reason deviations can be possible in the range of the display
levels and the order of the display sequences.
