SMX II Control Systems • Installation
Warning
Make sure all power is off before opening any
electrical box.
Installing the SMX Keypad/Display
To be operated satisfactorily, the SMX keypad/display
should be installed so it is both visible and accessible. It
should be placed in plain view and within easy reach of the
operator. Overhead locations are discouraged since they
make it very difficult to use the SMX control.
Select a spot on an interior, vertical surface. This can be an
inside or outside wall, partition or other permanent struc-
ture with rear access for wiring. The SMX control operates
on low voltage DC and is certified ignition-protected. The
space behind the SMX control does not have to be venti-
lated since the control components do not produce heat.
SMX II Only
The SMX II keypad/display requires a cutout of 2 9 /
16
" x 7 1 /
8
"
(65mm X 181 mm). (For SMXir keypad installation, refer to
drawing #086800 in the back of this manual.)
After cutting the hole for the keypad control, make sure it
fits and the printed circuit board is clear of the bulkhead
and that no objects of any kind are in a position to contact
the SMX circuitry. Plug the interconnect cable in and route it
to the Power/Logic (P/L) box. Refit the control in the hole
and secure it with four No. 6 x
3
/
8
inch screws. Hook the
decorative plastic cover at the top, press it flat from the top
down, and snap it in place at the bottom.
Retrofitting SMXir Keypad/Display to
Original SMX II or 3-knob
Adapter plates are available to cover the old vertical or
horizontal rectangular cutout and mount the SMXir keypad/
display. Part #5103612 is a black plate, and #5103612W is
white. Use adapter #4163805 to connect an existing CX
cable to the SMXir display. (Refer to the SMXCABLE
drawing, Figure 9, at the back of this manual.)
Installing the Power/Logic Box
(retrofit only)
All SX and FX systems with integrated SMX II controls have
the P/L box already installed on the unit.
In selecting a location for the Power/Logic box, bear in mind
that several sets of wires will be connected to it. Refer to
installation diagrams in this packet.
• The SMX P/L board is ignition protected, enclosed, and
operates in ambient temperatures up to 130°F (54°C).
• The P/L box may be installed in any position.
• The P/L board dissipates heat when operating, and must
be installed in a ventilated location.
• The P/L box is NOT waterproof and must be placed
where it will NOT get wet.
The power input to the board can be 115V or 230V. The
board automatically adjusts to either voltage.
Installing the Temperature Sensor
(remote systems and retrofit only)
The TSEP temperature sensor measures the cabin air
temperature and relays the information to the power/logic
board. The sensor is 1" long by ¼" diameter (25mm x 7mm
diameter) and is attached to a length of flat, 4-conductor
cable with a RJ-11 phone type plug at the end. Different
lengths of TSEP cables are available, from 2 feet to 80 feet
(.6m to 24m).
For best results, the sensor should be placed in the return
air path, away from the system evaporator coil. Directly
behind the return air grill is often a good location. The
sensor must not touch the evaporator coil, or be placed in
the discharge air.
With the TSEP in the return air path, use the default mode
of continuous fan operation for the most accurate tempera-
ture control. If intermittent fan operation is desired (fan on
and off with the compressor), the sensor must be wall
mounted on an INSIDE surface not subject to any influence
from heat outside of the area (including direct sunlight).
Thermistor covers are available from Taylor Made Environ-
mental, Inc. for wall mounting.
SX self-contained units with integrated SMX II P/L box will
have the TSEP already installed. On FX remote units, the
TSEP must be run from the P/L box on the FX unit to the
return air path of the cooling unit.
The TSEP cable plugs into the RJ-11 jack on the P/L board
marked “INSIDE TSE”. Coil up any excess cable, and tie out
of the way.
