s. Cooled Air System Indicating Lamp (No. 2 system)
(fig. 2-6).
(1) Description. A filament type press-to-test lamp with
a green lens.
(2) Purpose. Illuminates to indicate that the No. 1
cooled air temperature control is calling for cooling.
t. Cooled Air System Indicating Lamp (No. 2 system).
(1) Description. A filament type press-to-test lamp with
a green lens.
(2) Purpose. Illuminates to indicate that the No. 2
cooled air temperature control is calling for cooling.
u. Cooled Air System Temperature (Thermostat)
Control (No. 1 system).
(1) Description. An electronic thermostat control,
connected
to
the
thermister-temperature-sensitive
elements in the return air ducts.
(2) Purpose. Provides progressive adjustment of the
cooled air output temperature from the No. 1 cooled air
system. Lowers the output temperature when rotated
counterclockwise and raises the output temperature
when rotated clockwise.
v. Cooled Air System Temperature (Thermostat)
Control (No. 2 system).
(1) Description. An electronic thermostat control,
connected
to
the
thermister-temperature-sensitive
elements in the return air ducts.
(2) Purpose. Provides progressive adjustment of the
cooled air output temperature from the No. 2 cooled air
system. Lowers the output temperature when rotated
counterclockwise and raises the output temperature
when rotated clockwise.
w. Heat Range Select Switch (No. 1 system).
(1) Description. A four position rotary switch.
(2) Purpose. Selects one of the three heating ranges
(LOW, MED, HIGH) as desired for the No. 1 heated air
system. Limits the travel of the heat control valve in the
opening direction (26 percent, 50 percent and full open).
Provides an OFF position for shutdown of the heated air
system.
x. Heat Range Select Switch (No. 2 system).
(1) Description. A four position rotary switch.
(2) Purpose. Selects one of the three heating ranges
(LOW, MED, HIGH) as desired for the No. 2 heated air
system. Limits the travel of the heat control valve in the
opening direction (25 percent, 50 percent and full open).
Provides an OFF position for shutdown of the heated air
system.
y. Heated Air System Temperature Control (No. 1
system).
(1) Description. An electronic thermostat control,
connected to thermistor-temperature-sensitive elements
in the return air ducts.
(2) Purpose. Provides progressive adjustment of the
heated air output temperature within the heating range
selected by the heat range select switch, from the No. 1
heated air system. Lowers the output temperature when
rotated
counterclockwise
and
raises
the
output
temperature when rotated clockwise.
