MOUNTING AND INSTALLING THE CONTROLLER
The PX1 should be wall mounted. This is easy to do using its removable back plate, which has four
holes that can be used for mounting. The top center hole is a “keyhole” style hole which can be used
with a single large screw, so that the plate is hung on the screw head. For a more secure alternative,
there are also three smaller holes in the plate which can be used to screw it tightly to a wall surface.
The lateral measurement between the top two of these holes is 3⅛", and the lower hole is ¾" below
the top two, centered between them. Once the back plate is secured to the wall surface, the PX1 unit
can be snapped onto the back plate.
Once the PX1 is securely mounted to the wall, plug the included AC adapter into a power outlet and
connect the other end to the PX1’s AC input jack on the bottom panel. Next plug the temperature
probes into the corresponding jacks on the bottom panel and run your probe cables their full length
up to and across the ceiling if possible, toward the center of the grow space. Ideally, suspend the
probes down into the space above the plant canopy if possible. Take care not to stress or damage
the probe cables when securing them to walls and ceilings. NOTE: A bare probe receiving direct HID
light can cause premature dimming and/or inaccurate temperature readings. When setting up the
temperature probes, shield them from exposure to direct light. Download a probe shield on the PX1
product page at hydrofarm.com or make a shield from an upside down paper or plastic cup.
