Description 

 

2.0.3

The RTL 520 zone controller has 4 technical setting menus. Access to, display of, or amendments to the data are established by 

the configuration of the zone which has made MRL 608 C1 the master.

This allows the administrator to also make technical settings locally, subsequently removing this option, preventing the user of 

the zone from interfering with said technical settings, even inadvertedly. 

TO ACCESS THIS MENU: PRESS

 

 

FOR AT LEAST 15 SECONDS, UNTIL "TEST" APPEARS.

REMEMBER THAT THESE MENUS ARE ADDRESSED TO TECHNICAL STAFF
