L-2066 Operation

Note

On SMX II systems built before 8/98, press SLOW, FAN and
FAST simultaneously to adjust fan response differential.

Low Fan Speed Adjustment

 

(Factory Default: 32)

You can adjust the lowest fan speed to suit individual
preferences. For instance, you may wish to decrease the
low fan speed setting in your stateroom to minimize fan
noise.

To adjust low fan speed:

• Enter the programming mode: Press OFF, Press SET

• Press DOWN and SET simultaneously. The current low

speed reference number will be displayed (factory set
at 32).

• Press UP or DOWN to raise or lower speed reference

number.

• Press OFF to exit the programming mode.

Hint

You should normally keep the low fan speed at the highest
possible setting, consistent with a comfortable noise level,
for most efficient operation of your Cruisair system. Run-
ning the fan speed too slow can damage the compressor.

High Fan Speed Adjustment

 

(Factory Default: 60)

A blower will often reach its highest speed at a voltage
lower than full line voltage. For example, at a line voltage of
120V, the blower might reach its fastest speed at 110V. At
higher voltages, the bower speed will not increase signifi-
cantly.

The SMX High Fan Speed Adjustment allows you to set the
maximum high-speed voltage to the threshold of the blower
high-speed response. Because SMX breaks up the fan
speed voltage steps into 5 equal parts (between the low-
speed and high-speed adjustments), accurately setting the
high-speed adjustment can help ensure that each fan
speed step results in a noticeable change of fan speed.

To adjust the high fan speed:

• Enter the programming mode: Press OFF, Press SET

• Press SET and SLOW simultaneously. The current high-

speed reference number will be displayed (factory default
is 60).

• While listening to the fan noise level, use the UP key to

raise the displayed value past the point that you can hear
an increase in the fan noise level.

• Press the DOWN key to lower the voltage until you hear

a drop in fan speed, then raise that number up by 2 or 3
to ensure that it is set at the highest speed.

• Press OFF to exit the programming mode.

Fan Mode

 

 

(Factory Default: Continuous)

You can select continuous fan operation or instruct the fan
to cycle on and off with the system compressor.

To select continuous or intermittent fan:

• Enter the programming mode: Press OFF, Press SET

• Press DOWN, FAN and UP simultaneously.

• Use the UP or DOWN key to select C (continuous) or

I (intermittent).

• Press OFF to exit the programming mode.

Hint

If you select intermittent fan operation, you should relocate the
thermistor from the return air duct to an inside wall to best
sense room temperature. Check with your dealer or call the
Cruisair Applications Department for more information.

AC Line Voltage Calibration

 

The SMX control assembly has a built-in voltmeter that
senses AC line voltage. The microprocessor automatically
responds to sustained low-voltage conditions by shutting
down the air conditioning system to prevent compressor
damage.

At installation, the SMX voltmeter is calibrated to line
voltage /- 1%.

To check or recalibrate AC line voltage:

• Enter the programming mode: Press OFF, Press SET

• Press DOWN and UP simultaneously. Line voltage will be

displayed in 2 digits. On 115V systems, 95V appears as
95, 100V as 00, and 120V as 20. For 230V systems the
reading shows 1/2 of line voltage, therefore, 190V will
appear as 95, 200V as 00, and 230V as 15.

• To check accuracy or to calibrate, turn off all on-board

AC loads and measure the line voltage with an accurate
voltmeter.

• If the SMX displayed voltage is not correct, press the UP

or DOWN key to enter the correct value.

• Press OFF to exit the programming mode.
