C.A.P. PPM-4 Quick Start Manual

PPM-4 PPM-4
C.A.P. offers a full range of equipment for the growing enthusiasts.
The PPM-4 is the simplest, safest and most affordable CO
available today... from any manufacturer. Perfect for controlling LP
or natural gas generators with PPM accuracy.
Overview
• The PPM-4 is a two-piece controller that includes
a wall mounted infrared sensor with a 10 ft. cord
and a plug-in pass-through controller/power supply.
• The plug in control is designed to be electrically safe.
• Designed specifically to control the carbon dioxide
level in your grow environment with PPM accuracy
and is easy to use out of the box due to its easy to
read 3 LED interface.
• Switching set point factory set to 1450 PPM
with 50 PPM hysteresis/dead-band.
• Calibration couldn't be easier. Simply step outside
and press a button.
• The PPM-4 is easily mated to any 120 volt valve or
CO Generator with a simple plug in device.

Installation
1. Plug the controller into an active wall plug that will provide a
constant source of power. Once plugged in the unit should
illuminate the red "POWER" LED on the upper right face of
the plug in unit indicating proper functioning.
2. Unwind the CO controller cable and plug it into the port at the
2
top of plug in controller. The green LED on the front of the wall
mount sensor should illuminate when power is provided to the
plug in controller. This cable provides power and data transmission
functionality to the unit and must be connected for the unit to
work properly.
3. Hang the controller by sliding the keyhole mounting hole on the
back of the wall mount sensor over a nail or screw (provided)
at the desired CO measurement location (typically at mid level
2
between the ceiling and floor). You can either use a single
screw or two screws spaced 3
4. Plug the CO valve or generator into the wall-mounted
2
plug-in controller. The "On" indicator light on the plug
in unit will indicate when the power is switched on to
your CO generator.

Note: The controller can handle a maximum load of 10 amps.
If this rating is exceeded the warranty will be void.

Operation
The PPM-4 controller has been factory programmed to provide
an optimum CO maximum control set point of 1450 PPM. When
2
levels are below 1400 PPM (a 50 PPM hysteresis/dead-band), the
plug-in controller will power the CO
levels exceed 1450 PPM the controller will deactivate power at
the plug-in controller.
In most greenhouse operations CO
plants are exposed to light. As a result you may wish to also include a
timer with your setup. If using natural light, or a timer used to activate
lighting, the plug in controller should be installed after the timer so
that constant power is provided to the timer.
