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 modified
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.

5.0 to 20.0°C
1.0 to 10.0°C
CHECK THE FILTERS
The values correspond to the unit's maximum air flow.
If there is a variation in the fan speed, these values are reduced proportionally

CHECKING WHETHER HUMIDITY THRESHOLDS ARE EXCEEDED
40 to 100% RH if P09 = 0
(P109 + P110) to 100% RH if P09 > 0
10 to 40% RH if P10 = 0
10% RH to (P115 - 116) of P10 > 0
0: no
