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 before using the equipment, and you
should keep it on your boat for future reference. If there are
any 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).

Hint
Normally, in an SMX Online Net system, a single out-
side thermistor is used to send temperature readings to
all of the SMX Online control panels. This means you’ll
get the same readout of outside temperature at all sta-
tions.
14. Aux Heat Indicator.

press the AUX HEAT key to select the aux heating
mode.
8. Inside Temperature Indicator.

switchover mode, both the RUN and AUX HEAT indica-
tors are lit.
15. FAN Key.
Controls fan operation. Selects manual or automatic
fan speed control. Press once to select manual
control. The LED above the key lights. Press FAN
again to select automatic fan speed control. In this
mode, the fan speed is controlled by the microprocessor as a function of the difference between
setpoint and inside temperature.

Basic Operation
SMX II and SMX Online Network
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.
SMX
Online
SMX Online Network
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.
SYSTEM OFF
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 cur-
rent operating configuration in permanent memory ev-
ery 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.
SMX II
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.

SELECTING THE RUN MODE
Run
Press the RUN key. The Run Indicator above the
RUN key will light to show that you have selected the
run mode. Once the run mode has been selected
there are other parameters that determine how/when
the air handler will begin conditioning the air. They
are as follows:
For air handler to activate in cooling while in the run
mode the following conditions must exit:
• The tempering unit is in the cooling mode.
• The loop water temperature is below 65° F.
• The room temperature is above the setpoint of the
cabin control.
For air handler to activate in heating while in the
run mode the following conditions must exit:
• The tempering unit is in the heating mode.
• The loop water temperature is above 85° F.
• The room temperature is below the setpoint of the
cabin control.
SELECTING THE
AUX HEAT MODE
Aux
Heat
Press the AUX HEAT key. The Heat Indicator above
the AUX HEAT key will light to show that you have
selected the Aux Heat mode. For the Aux Heat mode
to function the following conditions must exist:
• The electric Aux Heater must be installed.
• The Aux Heat must be enabled.
(See Programming AUX HEAT, pg. 15)
• The room temperature is below the setpoint of
the cabin control.
NOTE: If the loop water temperature is above 85° F
the by-pass valve will also open allowing the hot
water to circulate through the coil at the same time
the electric aux heater is energized.
