System Check
• Product should be installed and serviced in accordance with applicable
national, state, and local building and electrical codes.
• Risk of re or electrical shock. Install transformer at least 10 ft
(3.05 m) from pools, spas, or fountains.
• Outdoor, above ground installation only. For use with low voltage
landscape lighting only.
• Transformer has a built-in circuit breaker which can be reset by removing and
then restoring power.
• Transformer must be connected to GFCI-protected receptacle marked suitable
for wet locations. Receptacle must be protected by a weatherproof cover.
• Do not submerge the transformer or use it to power submersible lights or lights
mounted in or near pools, spas, or fountains.
• If cleaning is necessary, use a damp cloth to wipe down case. Do not spray
transformer with pressurized water or steam.
• Do not use with dimmer or extension cord or wire in parallel with other
transformers.
• Do not exceed 70% of the maximum wattage of the transformer when
connecting lights.
• Transformer must be mounted in a vertical orientation, with the bottom at least 1
ft from the ground.
• Ensure all mounts are securely attached and will support the transformer’s
weight. Failure to properly support transformer may result in damage or injury,
for which the manufacturer does not assume responsibility.
• Do not attempt to disassemble or modify transformer.
• Ensure wiring to lights is correct gauge for the run and total power of the
intended circuit and is intended for use with outdoor landscape applications.

Check product label for specific electrical
specifications related to installation.
Improper installation will void warranty.
Mount transformer to solid surface using stainless hardware capable
of supporting the weight of the transformer. Hardware is not included.
Once screw(s) are properly mounted, slide transformer over screw
heads and tighten screw(s) to lock in place once the
transformer is level.
Total load (watts or volt-amperes) of all xtures connected to one
transformer must not exceed 70% of the W or VA capacity of the
transformer. Use the below equation to calculate the most
suitable transformer.
total xture load (W or VA) ÷ 0.7 = minimum transformer capacity
After installing entire system, apply supply power. After ve minutes
of operation, remove supply power. Check all low voltage electrical
connections, which should be cool to the touch. If any connection is
warm to the touch, check and re-tighten the connection and repeat
the process until all connection problems are resolved.
12 AWG landscape wire is generally recommended. For optimal
results, lights should be distributed evenly along the cable run, with
higher power lights being closest to the transformer. Higher voltage
terminals can be used with longer runs to make up for
slight voltage drops. The below equation and table can be used to
select the appropriate wire gauge for an application.
Note: When connecting wiring to transformer, do not loosen top
terminals on 75 W models as they are for internal wiring only.

With all gray tabs set at the inner position, the timer will not a󰀨ect
function and the connected lights will stay on unless power is
switched o󰀨.
1. To set up the timer, begin by rotating the timer dial until the arrow
on the right points to the current time
2. (this system uses a 24-hour clock).
3. Next, slide dark gray tabs outward at times when system
should be powered o󰀨.
Note: The system can be manually turned o󰀨 using the
main power switch as well.

Optional Mechanical Timer Operation (150 W/ 300 W) Optional Digital Timer Operation (150 W/ 300 W)
Optional Photocell Installation
Digital Timer (LVT-TD)
Before beginning to adjust settings, plug the timer in and press
the reset (‘R’) button with a paper clip to ensure the timer is at
factory default settings before use.
Setting Date/Time
1. With supply power on, press and hold the ‘CLOCK’ button.
2. With ‘CLOCK’ held down, press the ‘HOUR’ button to select
the hour, ‘MIN’ button to set minutes, and ‘DAY’ button to
select day of week.
3. Release ‘CLOCK’ button to save settings.
Setting Switch Times/Days
Timer can store information for up to 20 programs, with
independent ON and OFF settings for each program.
1. With supply power on, press the ‘SET’ button until you
reach the desired ON or OFF setting. Each pair of ON and
OFF settings will need to be set to work together for proper
operation.
2. Use the ‘HOUR’ and ‘MIN’ buttons to set the ON time, then
press ‘DAY’ button to select day or combination of days of
the week.
3. Press the ‘SET’ button to move to the OFF settings and adjust
using the same process.
Photocell (LC-115)
1. Remove supply power.
2. Remove knockout from transformer box.
3. Remove inner nut, feed wire through, and attach photocell to
housing by reinstalling and tightening inner nut until locked in
place.
4. Connect photocell to the photocell plug on the transformer.
5. Close the transformer and reapply supply power.
Operating Modes
Press the ‘MANUAL’ button to cycle between operating modes.
OFF - Lights will remain o󰀨 and set programs will not be activated.
ON - Lights will remain on constantly and set programs will not be
activated.
AUTO/ON - Lights are currently on and set programs are active.
AUTO/OFF - Lights are currently o󰀨 and set programs are active.
Randomize Setting
This allows lights to come on ±30 minutes from the set time to give the
appearance of an occupant manually switching the lights on or off. This
can be activated by holding the ‘HOUR’ button for 3 seconds until ‘RND’
appears on the screen. Holding the ‘HOUR’ button again for 3 seconds
will deactivate this feature.
Daylight Savings Setting
Hold the ‘CLOCK’ button for 3 seconds until the ‘+1h’ icon appears and
the time will advance one hour. Holding the ‘CLOCK’ button again for 3
seconds will deactivate this and return the time to normal.
Mechanical Timer (LVT-TM)
‘OUTLET ON’ setting on the side of the timer can be used to
manually bypass the timer and allow the connected lights/
transformer to stay on at all times.
To set up the timer, begin by making sure the timer is set to
‘TIMER ON’ and rotate the timer dial until the arrow points to the
current time. Next, pull gray tabs outward at times when the light
system should be powered o󰀨. Times where the gray tabs are
pushed in will be the only times the system will be switched on.
