compartment windows.
General Description
The control cabin anti-icing system uses electrical power to
heat the flight compartment windows.
The controls and indications for the control cabin window antiicing
system are on the P5 overhead panel.
Window heat control units (WHCUs) are part of the control cabin
window anti-icing system. The WHCUs do these things:
* Monitor window temperatures
GUN 001-099, 101-118
* Supply ON and OVERHEAT system indication
GUN 201-999
* Supply OFF and OVERHEAT system indication
GUN ALL
* Do system tests
* Program power output to the windows.
The WHCUs control power to these windows:
* No. 1 left and right
* No. 2 left and right.
Thermal switches monitor window temperature and control
power to these windows:
GUN 201-999
* No. 3 left and right
GUN ALL
* No. 4 left and right
* No. 5 left and right.
Windows in the thermal switch control systems are not part of
the P5 overhead panel indication and test functions.

General
The flight compartment windows are of laminate construction.
One layer is made of a conductive coating. Electric current from
the window heat system flows through the conductive coating.
The resistance of the conductive coating produces heat and
warms the window.
Power terminals and bussing strips in the windows connect the
conductive paste to system power.
Windows 1 and 2 have resistance type temperature sensors for
feedback to the window heat control units. There are two
sensors in each window:
* A primary sensor
* A spare sensor.
The WHCUs use only one sensor. If the primary sensor fails,
use the spare sensor. This prevents window removal for a
single sensor failure.
The other windows do not use window heat control units and do
not have sensors. The thermal switches control the window
heat power to these windows.

Purpose
The window heat control units (WHCUs) do these things:
* Sense window temperature
* Apply current to the window heat system when necessary
* Control current to the window heat conductive coating to
prevent thermal shock
* Control the P5-9 window heat status indication
* Have circuitry for P5-9 OVHT and PWR TEST
* BITE.
The windshield sensor switches are for the number 1 windows
only. The windshield sensor switches let you change the
primary sensor to the spare sensor.
Location
The window heat control units are in the EE compartment. Two
are on the E4-2 shelf and two are on the E2-1 shelf.
The windshield sensor switches are on the forward outboard E4
stanchion rack.
General Description
There are four identical WHCUs. Each WHCU controls the heat
