The ECAM COND page contains all graphical symbols associated with the air conditioning system.
Let us now look at all the parameters in details
NOTE: The YELLOW BOX is only for the purpose of highlighting.
1. Zone temperature
Each temperature value is displayed in green, when it is correctly transmitted by the SDAC.
Temperature value varies from -99 to 255 by step of 1°C.
When the information is not correctly received, the value is replaced by amber XX.
2. Duct Temperature
The duct temperatures are displayed in green when their value is below 80 deg.C and correctly received from the SDAC.
The duct temperatures are displayed in amber when their value is above 80 deg.C and correctly received from the SDAC.
The duct temperatures are replaced by amber XX when their value is not correctly received by the SDAC.
3. Zone Trim Air Valve Position
The arrow is green while the scale is white.
The two letters, C for Cold (valve fully closed) and H for Hot (valve fully open) are white.
Each zone trim air valve position is displayed in green, when the information is correctly received from the SDAC.
When the position is not available the positions are replaced by amber XX.
4. Pack Control Mode
No data is displayed when the Air Conditioning System Controller (ACSC) operates correctly and data from the SDAC is correctly received.
ALTN MODE is displayed in green when the ACSC is faulty.
PACK REG is displayed in green when the ACSC is not valid and at least one SDAC is valid.
5. Cabin Recirculation Fan Status
The FAN indication is displayed in amber when the recirculation fan fault information is correctly received from the SDAC.
When this information is not available, or when the fan is not faulty, the indication is not displayed.
