Notes on installation
Q module 5.5 heat
may only be mounted on heat meters of the
Q heat 5
series and calculator units of the
R 20 / 21
series.
If the module is used on a calculator unit of the type
R 20 / 21
,
installation must be carried out after the calculator unit has been
started up. If the module already has an error 00000, it must be
removed from the calculator unit. The error message will be reset
after a few minutes.
Do not use solvents on the radio add-on module.
Before beginning mounting of the add-on radio module, the net-
work must be set to installation mode.
Since data transmission is implemented optically, it must be en-
sured that the windows of the transmission units, both on the radio
add-on module and on the meter, are clean and not damaged.
