L-2066 Operation
Basic Operation
Power On
When AC power is applied to the system at the circuit
breaker, the SMX microprocessor performs a self-check
and retrieves from permanent memory the last operating
configuration. This process takes about four seconds, after
which the system will begin operating just as it had been
when power was last turned off.
System Off
Press the OFF key to turn the system off. Note that the
data display remains energized even when the system is
off. The fan can be turned on manually when the system is
in the off mode.
Note
The SMX has built-in protection against sudden power in-
terruptions. The system automatically stores the current
operating configuration in permanent memory every time
you make changes. (The new operation mode must be in
affect for 30 seconds before it is saved into permanent
memory.) When AC power is lost, the SMX system retains
these settings, and when AC power is restored it resumes
operation using the same settings as before.
Selecting Setpoint
Press the SET key and the current setpoint will be dis-
played. Press the UP or DOWN key to change the setpoint.
Displaying Temperature
To display cabin temperature, press the TEMP key. Press
TEMP twice for an alternating display of inside temperature
and setpoint. Press again to return to inside temperature
only.
Cool Mode
To enter the COOL mode, press the COOL key. The Cool
Mode Indicator will light to show that you have selected the
cooling mode.
The Cooling Indicator will be lit whenever the system is in
the cooling mode and the compressor is running. When the
compressor cycles off, the Cooling Indicator goes off, but
the Cool Mode Indicator stays on.
Heat Mode
Press the HEAT key to select HEAT Mode. The Heat Mode
Indicator will light to show that you have selected the
heating mode.
The Heating Indicator will be lit whenever the system is in
the heating mode and the compressor is running. When the
compressor cycles off, the Heating Indicator goes off, but
the Heat Mode Indicator stays on.
Automatic Changeover
Press the COOL and HEAT keys simultaneously for
AUTOMATIC CHANGEOVER between COOL and HEAT
Modes. Both mode indicators will light, to show that the
system is in the automatic changeover mode.
For the SMXir Remote Control only
- Press the Auto
Switchover key to enter automatic changeover mode.
Note that the Cooling or Heating Indicator will come on
when the compressor is running to show when the system
is running in the cooling or heating mode.
Manual Fan Speed Control
Press the FAN key to select manual fan control. The Manual
Fan Indicator will light to show that it is in the manual mode.
Then use the SLOW and FAST keys to select the desired
fan speed.
Note that you can use the manual fan control to circulate air
even when the system is in the OFF mode.
Automatic Fan Speed Control
If in manual fan mode, press FAN key to select automatic
fan control. The Manual Fan Indicator goes off, and the
system will automatically adjust fan speed as the cabin
temperature deviates from the setpoint. As setpoint is
approached, the fan speed automatically slows. Once
setpoint is reached, the compressor cycles off and the fan
keeps running on low speed.
Adjusting Brightness
Pressing the SET key repetitively will dim the LED display.
Keep pressing SET to return to full brightness.
