Operating instructions

130
Ensure that the compressor is operational by:
A.Placing mode switch to cool.
B.Lower temperature setting to start compressor operation
(approx. 2 min. time delay)
C.Once compressor is operational adjust setting up to shut
down compressor system.
Locate sensor attached to zone being tested. Using a hair
dryer or other heat producing air device, GRADUALLY heat
up the area surrounding the thermistor. Ensure that device
does not place excessive heat on plastic cover.
If compressor system comes on, sensor is operational
If the compressor does not come on, reverify connections at
air conditioner.
If the system is still not operational, unplug sensor from unit
and verify its cable by checking the ohms.
For the specific temperature surrounding the sensor, the
ohms readings should be as follows:
At room Temperature You Should Have
of: Ohms Reading of:
55°F 11667
60°F 10212
65°F 8959
70°F 7876
75°F 6939
80°F 6126
85°F 5418
90°F 4802
95°F 4264
100°F 3793
NOTE: Any ohms reading has a tolerance of plus or minus
(±) 10% to be a good component. A very precise and
accurate ohm meter must be used before condemning
the sensor.
The proper location of the Remote Sensor is very important to
ensure that a comfortable RV temperature is maintained.
Observe the following rules when selecting a location.
n Locate the Remote Sensor 54" above the floor.
Install the Remote Sensor on a partition, not on an outside
wall.
n NEVER expose it to direct heat from lamps, sun or other
heat producing items.
n Avoid locations close to doors that lead outside, windows
or adjoining outside walls.
n Avoid locations close to cold air supply registers.
n Avoid area with air stagnation such as under cupboards.
Improper location can cause improper operation of the unit,
such as repeated on/off cycle.
6.AC POWER MODULE BOARD
The AC power module board consists of relays, Dip
switches, plug receptacles and other components. If any
one of these are defective, the complete AC power module
board must be replaced. The 3-amp fuse is the only
replaceable component.
The board is a signal receiver and completes AC volt
circuits according to what signal it receives. Before diag-
nosing the AC power module, verify Configuration
Operation, Comfort Control,
DC volts are within operation range and
115 volts AC is supplied to the AC power module board.
A.ROOFTOP AIR CONDITIONERS
To verify circuits are being completed by the AC power
module board, you would first disconnect the 6-pin plug
connector from the electric kit.
