TEMPERATURE REGULATION
The zone controller regulates the temperature of the two cabin zones and the cockpit
BASIC TEMPERATURE REGULATION
The flight crew uses the temperature selectors on the air conditioning panel in the cockpit
to select the reference temperatures. The zone controller computes a temperature demand
from the selected temperature and the actual temperature.
The actual temperature is measured by sensors :
- in the cockpit, for the cockpit zone
- in the lavatory extraction circuit and galley ventilation system, for the cabin.
A signal corresponding to the lowest demanded zone temperature goes to the pack
controller, which then makes both packs produce the required outlet temperature.
OPTIMIZED TEMPERATURE REGULATION
The zone controller optimizes the temperature by action on the trim air valves
The temperature selection range is from 18~C (64~F) to 30~C (86~F).

Each controller consists of a primary channel that is normally in control and a secondary
channel that acts as a backup if the primary channel fails.
ZONE CONTROLLER
PRIMARY CHANNEL FAILURE
The secondary channel operates as backup.
The flow setting function and optimized temperature regulation are not available. HOT AIR
and TRIM AIR valves close.
The zones are controlled to 24~C (76~F) (backup regulation). Pack 1 controls the cockpit
temperature. Pack 2 controls the FWD and AFT cabin temperatures.
ALTN MODE appears on the ECAM (Electronic Centralized Aircraft Monitoring) COND page.
SECONDARY CHANNEL FAILURE
This has no effect on zone temperature regulation
