6.1.3 - Reading parameters (sub-menu 3.3)
This third sub-menu gives access to all the values (temperatures, relative humidities, pressures, time delays, meters, input and output
states, etc.) managed by the CCU CONTROLLER.. Only the useful parameters are displayed. They cannot be modied
The meters can be reset to zero. To do this, place the cursor on the chosen meter and simultaneously press the Reset and 0 keys for
5 to 6 seconds.
All these parameters are accessible from the "customer" access level.
