Programming The SMX II and SMX Online Net
SMX control systems are programmed at the factory for average values. For optimum performance, you may wish to change these
settings to suit your individual preferences.
follow these steps:
• Enter the programming mode:
Press OFF.
Press SET.
• Press DOWN, SET and UP simultaneously. The delay in
seconds will be displayed.
• Use the UP or DOWN keys to change the time to the
desired setting.
• Press OFF to exit the programming mode.
At initial power-up, you will see the countdown for each
compressor on the data display, if you are in the TEMP
mode. The countdown will not appear in the SET mode.
SMX Online Net only.
Compressor restart delays are automatically set with 4
second intervals when a cabin is given an ID number, You
can reset restart delays in increments of 1 second.
Compressor Restart Differencial
(Factory set: 1.5 degrees Fahrenheit)
The compressor response differential is the amount of
temperature change in the room needed for the compressor
to cycle on and off. The factory setting is 1.5 degrees
Fahrenheit, which should be adequate for most applications.
Differential selections are available in increments of 1/8
degrees. Thus, to select one degree, you should choose 8
(for 8 eighths).
To program the restart differential:
• Enter the programming mode:
Press OFF.
Press SET.
• Press SLOW and FAN simultaneously. The restart
differential will be displayed.
• Use the UP or DOWN key to change the setting.
• Press OFF to exit the programming mode.
Note
If you switch from Fahrenheit to Celsius for temperature
displays, the compressor restart differential will also operate
on degrees Celsius. Thus, the factory-set compressor restart
differential will be 1.5 degrees Celsius, which is quite wide.
To correct this, reset the differential value from 12 to 6. This
will provide a differential of about 0.75 degrees Celsius,
roughly corresponding to 1.5 degrees Fahrenheit.
This will also affect the Fan Response Differential, which is
factory set at a value of 4 for one-half degree Fahrenheit.
When shifting from Fahrenheit to Celsius, you should reset
the Fan Response Differential from 4 to 2. This will provide a
value that is roughly equivalent to one-half degree Fahren-
heit.
Factory Memory Reset
You can use the memory reset sequence to restore all
programmed functions to the factory settings. To do this:
To restore programmed functions to factory setting:
• Press OFF, SET and FAN simultaneously.
• Press SET.
• After a delay, the memory will be reset from stored values.
After another delay, the display will come back on normally.
Fahrenheit/Celsius Display
(Factory Set: Degrees Fahrenheit)
You can choose to view temperature in degrees Fahrenheit or
Celsius.
To select Fahrenheit or Celsius:
• Enter the programming mode:
Press OFF.
Press SET.
• Press DOWN, TEMP and UP simultaneously.
• Use the UP or DOWN key to select F for Fahrenheit or C for
Celsius.
• Press OFF to exit programming mode.
Note that changing from Fahrenheit to Celsius will affect the
compressor control differential and fan response differential,
since these settings will now be expressed in degrees Celsius.
You should reprogram these values.
Compressor Restart Time Delay
(Factory Set: 0)
This function is used when you have more than one air
conditioning compressor on board. You can program your
SMX with different restart time delays for each compressor to
avoid electrical overloads by restarting them one at a time at
startup.
SMX II
(Before 8-1-98)
You can select eight time delay values, from 0 to 70 seconds,
in 10 second increments. Thus, if you have three systems, set
one for 0, the second for 10 and the third for 20 seconds.
All SMX Models
(After 8-1-98)
You can select time delays in increments of 1 second.
To program time delay, go to each SMX switch, and
