INSTRUCTIONS
• Dim status:
- Day/Night indicates status of mer. Day means lights should be on
- > nnC or > nnF indicates that ballast is dimmed because of overtemperature condion
- mm:ss (example: 10:35) counts down during restrike delay if congured. NOTE: The restrike
lights will come on immediately when power is restored.
Power can be adjusted right on this screen by using Next from eld to eld, and Up or Down to adjust.
NOTE: Power level adjustments are “scky,” meaning that any changes made to them are saved by
default and will return again on power-up.
A. Press Page once to get to the status display page. The cursor will be blinking under the waage
seng for Zone A. With this seng you will determine the output level (dimming stage) at which
you wish to operate your ballasts. Press Up or Down to select your desired waage output for this
zone (available sengs are OFF, 600W, 750W, 825W, 1000W, 1050W, and 1150W, depending on
the lamp waage).
B. Press Next once to move the cursor down to the waage seng for Zone B. If you will not be
running lights in Zone B, set the waage eld to OFF.
C. Note that this page also displays the temperature as read by the temperature probes, the status of
the “Day” or “Night” seng for each zone, the date, and the me.
A. Press Page once to get to the Zone A sengs
page. The cursor will be blinking under the
ballast type eld. Press Up or Down to select
the waage seng that matches the waage
of the ballasts you will be running in this zone
(available sengs are 1000W, 750W, 600W, and 400W, depending on the lamp waage). NOTE:
If you wish, you can create a name for the zone controlled by this channel. This name can be up to
eight (8) characters in length (the default names are Zone A and Zone B on initial power-up).
B. Move the cursor to the hour eld in the On me seng. Press Up or Down to select the hour of
the me you want the ballasts to turn on.
C. Move the cursor to the minutes eld and select the appropriate minutes seng.
D. Move the cursor to the a.m./p.m. seng and select “a” or “p” accordingly.
E. Move the cursor to the hour eld for the O me seng. Press Up or Down to select the hour of
the me you want the ballasts to be turned o.
F. Move the cursor to the minutes eld and select the appropriate minutes seng for the me you
want to ballasts to be turned o.
G. Move the cursor to the a.m./p.m. seng and select “a” or “p” accordingly.
H. Move the cursor to the temperature seng for automac dimming on overtemperature. The
temperature that you set here will be that which, if sensed by the probe, triggers dimming of all
connected ballasts in Zone A in order to reduce the temperature of the grow environment. Be sure
to place the temp probe away from direct sunlight to ensure correct temperature readings. Always
use a shield with the temp probe.
I. Move the cursor to the Sunrise/Sunset seng (“S/R” in the display) and choose your desired
seng for the period of me during which the PX1 will increase power to the ballasts in Zone A
at the beginning of the lighng cycle from zero to full power to simulate a natural sunrise, and
decrease power to the ballasts at the end of the lighng cycle from full power to zero to simulate a
natural sunset. The sengs available are 0, 5, 10, 15, 20, or 30 minutes (0 = o).
