SMX II/SMX Online Net Controls • User Operation
Warning
This manual contains essential information concerning the
operation and maintenance of your SMX Series Control. It is
very important that you read and understand the contents of
this manual thoroughly bef ore using the equipment, and you
should keep it on your boat f or future ref erence. If there are an y
statements in this manual that you do not understand, contact
the Taylor Made Environmental, Inc. Service Department or
your local dealer for assistance .
Introduction
This manual covers SMX II and SMX Online Net SMX Series
computerized air conditioning controls.
SMX II. SMX Series switch assembly with soft-touch
membrane keys. Includes all programmable functions. It may
be used with the optional SMX Modem.
SMX Online Net. Multiple SMX Online Net units may be
linked together in a local area network. Each unit has all of the
programmable functions as the SMX II. In addition, it has
"click-type" keys, two-speed blower control and optional
outside temperature sensing. Additional programmable
features available with optional convenience panel. It may also
be used with the optional SMX Modem.
Most of the basic operating principles are the same for all
SMX Series systems, but there are some differences. For
instance, the SMX II only displays inside temperature, while the
SMX Online Net has an optional outside thermistor and can
therefore also display outside temperature. We have identified
those paragraphs applying only to specific systems.
If you need additional help, after reading these instructions,
please contact the Taylor Made Environmental service
department at 804-746-1313.
(OPTIONAL) SMX Modem. The SMX Telephone Data
Modem is sold as a separate unit and IS NOT included in a
standard SMX II or SMX Online Net System. If you have
purchased an SMX Modem, installation and operation of this
product is described in the SMX Modem Control System
Operation Manual (L-0896).

Basic Operation
SMX II and SMX Online Net
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.
Displaying Temperature
To display cabin temperature, press the TEMP key.
Selecting The Heating Mode
Press the HEAT key. The Heat Indicator above the HEAT key
will light to show that you have selected the heating mode.
The Heating Indicator to the right of the data display will be lit
whenever the system is in the heating mode and the compressor is actually running. When the compressor cycles off, the
Heating Indicator goes off, but the Heat Indicator stays on.
Selecting Automatic Changeover
Press the COOL and HEAT keys simultaneously. The
indicators above both buttons will light, to show that the system
is in the automatic changeover mode.
Note that the Cooling or Heating Indicator will come on to show
whether the system is running in the cooling or heating mode.
Operating The Auxiliary Heat Mode
SMX Online Net Only
If your boat is equipped with an auxiliary heating system, the
aux heat function is normally disabled. This means if you press
the HEAT key the system will run in the reverse cycle heating
mode without auxiliary heat (aux heat).
To enable the aux heat function see page 12.
When aux heat is enabled, press the HEAT key once to run
Reverse-Cycle heating only. Press the HEAT key twice quickly
to run aux heat. The Heat Indicator will flash slowly.
For automatic changeover, press HEAT and COOL
simultaneously.
SMX II Only
Press TEMP a second time for an alternating display of inside
temperature and setpoint. Press a third time to return to inside
temperature only.
SMX Online Net Only
If your boat is equipped with the optional outside thermistor,
press TEMP a second time to display outside temperature.
Press a third time for an alternating display of setpoint, inside
temperature and outside temperature. Note that the inside and
outside indicators show you which temperature is being
displayed.
Selecting The Cooling Mode
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 compressor is actually running. When the compressor cycles off, the
Cooling Indicator goes off, but the Cool Indicator above the
COOL key stays on.
Adjusting Fan Speed Manually
Press the FAN key to select manual fan control. The 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.
Adjusting Fan Speed Automatically
Press FAN a second time to select automatic fan control. The Fan
Indicator goes off. Now the system will automatically
6

English
adjust fan speed as the actual 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 Control
With the SMX Online Net, the display brightness is adjusted
automatically according to cabin lighting conditions.
SMX II Only
Press the SET key once to display setpoint. Press SET a
second time to dim the data display. Press it a third time to dim
the display further. Press it again, and it returns to full brightness.
Using The Humidity Control Routine
When engaged, the SMX humidity control routine automatically
turns the air conditioning system on at preselected intervals to
remove moisture from the air. The system is programmed at
the factory for average values. To change the factory settings,
see page 17.
To start the dehumidification program:
• Press OFF.
• Press COOL, HEA T and FAN keys simultaneously .
• The data display will flash HU , indicating that the prog ram is
active.
• To halt the dehumidification program, press any key. The HU
message will stop flashing.
Safety Note
Whenever the SMX system is in the dehumidification mode, all
of the system safeguard controls remain active. If the sea water
flow fails or if line v oltage falls below preset limits, the system
will automatically shut down. If AC po wer is interrupted, the
system will automatically resume operation in the dehumidification mode when power is restored.

Network Operation
SMX Online Net Only
A network consists of several SMX Online Net units connected
in a serial chain as shown below. Each SMX Online Net unit is
assigned a controller ID code, which serves as its unique
"address" on the network.
You can perform network functions from any SMX Online
Net control panel on the network, or from the convenience
panel.
A convenience panel is not necessary for network operation.
However, the convenience panel offers single-key control over
certain functions and allows operation of multiple units with a
single keystroke.
Controller ID Numbers
Normally, ID numbers are assigned when the system is
installed, and you will not need to change them. To make it
easier, you can use one of the two-letter codes for spaces such
as the Main Salon (SL) or Forward Stateroom (FS), or you can
use numbers.
selections until you see the one that you wish to assign to that
station. Note that if y ou scroll to the end of the list, you will
have to reverse direction to get back to the starting point.
• Press OFF to select the controller ID and exit the programming mode.
• Repeat the above steps at each SMX Online unit in the
network.
CONTROLLER ID CODES:
-- Null (no ID assigned) PS Port Stateroom
SL Salon SS Starboard Stateroom
LL Galley S1 Stateroom #1
Fb Flying Bridge S2 Stateroom #2

FS Forward Stateroom 12-28 Additional cabins
AS After Stateroom
To view or change the controller ID for a specific
station:
• Enter the programming mode:
Press OFF
Press SET.
• Press DOWN and OFF simultaneously. The null sign
(--) will appear in the data display if no ID has been assigned.
If an ID has already been assigned to that unit, the current ID
selection will be shown.
