Power On
When AC power is applied to the system at the circuit breaker,
the SMX microprocessor retrieves from permanent memory the
operating system and 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. Also,
you can turn the fan on and off manually when the system is in
the off mode.
Note
The SMX has built-in protection against sudden power
interruptions. The system automatically stores the current
operating configuration in permanent memory every time you
make changes. 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. The indicator above the key will light, and
the current setpoint will be displayed. Press the UP or DOWN
key to change the setpoint.

Press the COOL key. The Cool Indicator above the COOL key
will light to show that you have selected the cooling mode.
The Cooling Indicator to the left of the data display will be lit
whenever the system is in the cooling mode and the compres-
sor is actually running. When the compressor cycles off, the
Cooling Indicator goes off, but the Cool Indicator above the
COOL key stays on.
