14. TEMPERATURE LIMITING – If the owner wants the con-
trol temperature range to be less than as ships (60
it can be reduced using dip switches #1 - #4 of 8 on front
of the control. See charts on page 4.
15. SLEEP (optional) – Press the control pad key for SLEEP
and the indicator light will come on. The temperature set-
ting will gradually rise or fall over the next 2 hours. See
page 5 for more information.
16. TIMER (optional) – To turn the unit OFF using the TIMER,
proceed as follows: With the unit in operation, press the
TIMER key once to start the digital display blinking. While
the "0" is still blinking, press the TIMER key repeatedly to
select the number of hours before you want the unit to
turn OFF. After a few seconds, the display will switch back
to showing the temperature setting of the unit. If at any
time, you want to check the number of hours remaining
before the unit shuts off, press the TIMER key and the
number of hours will blink for a few seconds on the display.
To turn the unit ON using the TIMER, proceed as follows:
With the unit in operation, select the desired start-up mode,
fan speed and temperature setting. Then, using the ON/
OFF key, turn the unit OFF. Press the TIMER key once to
start the display blinking. While the "0" is still blinking,
press the TIMER key repeatedly to select the number of
hours before you want the unit to start. The number of
hours before start-up will continue to blink on the display
until the start-up takes place, (see page 5 for more info.)
17. MOTION SENSOR & DOOR SWITCH (Optional) – To acti-
vate, dip switch #3 of 4 must be OFF. Using the plug as-
semblies that ship with the unit, connect motion sensor
and door switch (both by others) to receptacles CN4 &
CN7 on front of control box. Program memory P1 & P2
(see page 5). To test, short the 2 prongs (located to the
right of the dip switches and labeled "T-SHRT") with wire
on tin foil to reduce the 15 minute delay to 3 minutes, and
the 14 hour delay to 6 minutes. Set mode and tempera-
ture on unit, (different than programmed for P1 & P2) then
exit room and close door. After 3 minutes re-enter the room.
Unit should now show settings programmed for P2. Again
set the mode and temperature on unit (different than pro-
grammed for P1 & P2). Exit room and close door. Wait 6
minutes then re-enter the room. Unit should now show
settings programmed for P1. Remove the short from T-
SHRT prongs to restore the normal 15 minute and 14 hour
time delays.
!
CAUTION
Failure to remove short for long term operation will dam-
age the equipment and void the warranty.

18. WIRELESS REMOTE CONTROLLER – If this optional ac-

F),
cessory will be used, check it out at this time. It will only
work with the control pad (either unit or wall mounted).
You should be able to control the unit from anywhere in
the room by pointing the remote controller at the control
pad.
19. HEAT PUMP OVERRIDE – For units with reverse cycling
heating, check the override feature. Note: The outdoor tem-
perature should be above 40
of the control must be OFF. Select the HEAT mode with
temperature setting calling for heat. The compressor and
outdoor fan should be operating and the room discharge
air should be warm indicating reverse cycle heating. (Unit
temperature setting must be no more than 2
temperature for reverse cycle to work. If more than 2
above, electric heat will energize). Slide dip switch #7 to
ON then unplug and plug in the power cord to activate the
changes. The compressor and outdoor fan should not
operate, but the unit should continue to discharge warm
air, indicating it is now heating with electric heat. This fea-
ture provides electric heating if the compressor fails, or if
reverse cycle heating is not sufficient at lower outdoor tem-
peratures. Leave dip switch #7 OFF for normal operation.
20. REMOTE WIRED THERMOSTAT – If a remote thermostat
will be used in lieu of the control pad, remove and discard
the control pad then install the decorative cover in its place.
Connect the low voltage remote thermostat wires to the 7
pin receptacle on the control box front, using the plug and
wire assembly provided with the unit (see figure 16, page
17). Mount and wire the remote thermostat per the instruc-
tions that come with it. Slide dip switch #1 of 4 to ON.
After this, unplug the power cord and plug it back in again
to reset the control for remote thermostat. For more infor-
mation, see pages 5 and 8. Check the operation of the
conditioner using the instructions supplied with the re-
mote thermostat.
21. DISCHARGE GRILLE – As shipped, the front panel dis-
charge grille will angle 35
This will normally give the best air circulation. However,
by removing 6 screws and reversing the grille, this angle
can be reduced to 15
has been decided, place the front panel back on the chas-
sis. Hook it at the top and snap it on at the bottom. Re-
place the two screws. The control door in the literature
packet should now be installed on the front panel.
