Step 4: AC Power Wiring
1. Plug the included 6-foot line cord into a 120VAC outlet. (E-SL1600
units for international use are prewired for 230VAC.)
2. Do NOT use a switch controlled wall outlet for operating an
irrigation controller.
Alternate Wiring
If you are mounting your SL1600 controller outdoors or local electrical
codes require hard wiring, proceed with the following steps.
Warning: Connecting the
SL1600 controller to the
primary power should be
done by a licensed electrician
following all local codes.
To prevent electrical shock,
make sure all supply power
is turned OFF at the breaker
before connecting these wires.
Electrical shock can cause
severe injury or death. This
controller is not intended for use by children. Do not allow children
to play with the controller.
1. Remove the screws that secure the AC Wiring Cavity Panel. This
will allow access to the transformer wiring.
2. Disconnect the existing line cord connected to the transformer
wires.
3. For use with conduit, simply remove the line cord knockout. To do
this, use a small, flat screwdriver blade in the slot of the knockout
on the underside of the controller housing. Tap out the knockout
with a hammer. Install the conduit and wiring. Discard the line cord.
For 120VAC operation, using wire nuts, make the wire connections
indicated in the chart below.
For 230VAC operation, using wire nuts, make the wire connections
indicated in the chart below.
4. Replace the AC Wire Cavity Panel and secure with the screws.
5. Return to the breaker box and turn on the circuit breaker. Verify
that the controller no longer displays “no AC.” This indicates that
the AC power is on.

Step 5: 24VAC Valve Wiring
WARNING: Never mix 24VAC and
high voltage wiring in the same
conduit.
• For solid wires, simply push
to insert the stripped end of
valve wire into the module
connector.
• For stranded wires, use a
small screwdriver blade to
push back the orange slide
lock trigger first, then insert
the stranded wire while holding the trigger in the open position.
When you release the orange slide trigger, the wire will lock in
place.
SL1600 Controller
Installation Instructions
• Knockouts: The SL1600
controller provides several
convenient knockouts for
your choice of routing for
valve and accessory 24VAC
wiring. The knockouts
should be removed by
striking with a hammer
and screwdriver inwards,
toward the inside of the
housing.
• COM (Valve Common):
Connect the Valve Common wire to the COM terminal.
• MV/P (Master Valve/Pump
Terminal): Connect one wire to the
COM position and the second wire
to the MV/P position. Polarity is
not important. Note that the total
current of the activated Pump
Start Relay AND valve(s) cannot
exceed the maximum output
current (default is 1.0A).
• SEN (Rain/Freeze/Wind Sensor):
If you are using an optional rain,
freeze, or wind sensor, use the SEN
terminals for these devices. There
is no polarity required for these
wires. Remove and discard the
factory installed wire jumper.
• Zone Wires: Connect a zone wire
to a terminal on the SLM4 Module.
Your SL1600 controller can power
a total of 3 valves concurrently or
a total of 2 valves with one master
valve. Take caution when
running a pump start
relay so maximum output
current does not exceed
1.0A. To locate a zone,
touch zone wire to the
TEST POST and determine
which zone valve is ON.
Note that the TEST POST
is HOT even when the
control panel is not in the
housing.
9V Battery Installation
(optional)
SL1600 controllers with firmware versions later than 1.10 do not require
a battery for clock time retention. A 9-volt battery may be installed for
operating the display when the panel is open or for programming while
the panel is outside the housing.
Step 6: Control Panel Installation
1. With the controller and optional SLW On-Site Weather Station
installation complete, re-insert the control panel into the housing.
To do this, hold the operating panel at a 90 degree angle from
the housing (see photo at right) and position the top of the panel
slightly toward the housing and slip the top post into the top
hinge, then push the bottom post into the lower hinge. The panel
should now swing open and close freely on the hinges.
2. The SL1600 controller will automatically restore power and
communication to the control panel as soon as it is firmly closed.
No ribbon cable is required.
Installation is complete! Proceed to your Owner’s Manual to program
your SL1600 controller.

Wiring
Note: To remove
wires, push back
the orange slide
trigger using a small
screwdriver and then pull out
the wire to remove.
Note: Your SL1600
controller utilizes
screwless terminals
for fast installation.
Note: If you are NOT
using an optional rain
or freeze sensor, the
wire jumper must be in
place for your valves to turn ON.
The jumper must also be in place
if you are using the SLW weather
station. SLW WEATHER STATION
DOES NOT ATTACH TO THESE
TERMINALS.
