CABIN TEMPERATURE CONTROL

CABIN TEMPERATURE CONTROL - DESCRIPTION/OPERATION
1. D /L
ESCRIPTION OCATION
The cabin environmental control system has been modified to allow the cockpit crew to transfer control
of the cabin temperature to the cabin switch panels. Cabin switch panels with temperature control
capabilities interface to the production cabin environmental control system through a potentiometer built
into the cabin management system Cabin Control Module 1 (CCM 1) (23-90-00). Flexible hoses and a
muffler assembly have been installed outboard of the dado panel at FS462R to facilitate air flow to the
relocated production cabin temperature sensor.

PERATION
NOTE: For the CABIN TEMP annunciator/switch to transfer temperature control to the cabin, the CABIN
switch on the cockpit overhead air conditioning panel must be in the NORM or STBY position.
The cabin temperature sensor draws cabin air through the muffler from an air inlet screen on the inboard
side of the dado panel at FS442R. The air is returned to the cabin from the cabin temperature sensor to
the forward side of the divan end cabinet, diffuser, and floor area.
To transfer cabin temperature control to the cabin, press the CABIN TEMP annunciator/switch to
extinguish the COCKPIT annunciator and illuminate CABIN. Cabin temperature control is returned to the
cockpit by pressing the CABIN TEMP annunciator/switch to illuminate COCKPIT, or by turning the
CABIN switch on the cockpit overhead air conditioning panel to the MAN position.
Relay K200HN disconnects the 1 k
temperature controller and connects the 1 k
to the cabin temperature controller, transferring temperature control to any cabin switch panel with
temperature control capabilities.
To adjust the temperature from the cabin, verify that the cockpit CABIN TEMP annunciator/switch is set
to CABIN. Then press CABIN TEMP and CONTROL ADJUST -/+ on the VIP Switch Panel. The selected
cabin temperature is displayed on the panel.
