INITIAL INSTALLATION INSTRUCTIONS
S.I.C.E. shielded communications cables are available from your preferred retailer,
or from www.growgps.com/store Sentinel S.I.C.E shielded communications
cables are available in 5 meter (part# SICEcbl5), 10 meter (part# SICEcbl10),
25 meter (part# SICEcbl25), and 50 meter (part# SICEcbl50) lengths.
These are NOT standard Ethernet cables. They are shielded to reduce interference
coming from digital ballasts, and are specially coated to not allow moisture
inside. The use of standard Ethernet cables in NOT recommended, and any harm
that comes from the use of non-Sentinel approved cables VOIDS any and all
warranties. The special coatings on these cables makes them less-flexible
than standard Ethernet cables. They are not intended to be highly flexible. It is
recommended after installation that the cables are affixed securely to the walls
or ceilings of your greenhouse or grow room in a manner that makes sure the
cables are not pinched or crushed.
While every effort has been made to shield your CPPM-4i from EMI (Electromag-
netic Interference) it is still not recommended to place your CPPM-4i main unit,
probes and cables to close to electronic or digital ballasts. It is not recommended
to run the S.I.C.E. cables in electrical raceways with digital ballast lamp cords.
TIP:
YournewSentinelCPPM-4iisthemostadvancedCO2controlleravailableonthemarket
today. It incorporates the proprietary S.I.C.E. – Sentinel Intelligent CO2 Enrichment –
communication and control components and programming that are unique to Sentinel.
This patent pending system allows for communications between Sentinel S.I.C.E series
products, providing a level of control never before seen in your greenhouse, garden or
grow room.
ThesystemworksbyaSentinelS.I.C.E.seriescontroller,suchastheSentinelCPPM-4i,
measuring and monitoring your growing environment. As the atmospheric CO2 levels
change, the controller will tell the ICG series generator to increase output, decrease output,
or go into idle mode…all computer controlled. In this way, a growing environment that
has very low CO2 levels, such as the start of the day or after a ventilation cycle, can be
rapidly brought back up to optimal growing conditions. As the optimal conditions are
reached, the S.I.C.E. system can decrease CO2 output, making sure that the user defined
optimal level is not overshot. As needed, the growing environment can be “topped off”
with CO2 enrichment on a lower output setting, allowing for air conditioners and
dehumidifiers to better deal with the heat and moisture loads associated with CO2
enrichment and maintaining more constant temperature and rH levels.
1. FollowinitialinstallationinstructionsforSentinelCPPM-4iandSentinelICG
Series generator.
2. ConnectCPPM-4itoICG-30withSentinelS.I.C.E.cableofappropriatelength.
(Cables available separately).
3. Set the desired CO2 levels for the S.I.C.E. control with the “Sentinel Intelligence”
button. Mode 1 is the “High” setting for the CO2 generator, meaning full output.
Mode 2 is the “Medium” setting for the CO2 generator, meaning 2/3rd output.
Mode 3 is the “Low” setting for the CO2 generator, meaning 1/3rd output. Make
sure to press the “Enter” button after each value.
It is important to note that since all growing areas are different, settings for the
S.I.C.E. control will have to be tailored to each environment for optimal function.
SENTINEL INTELLIGENT CO2 ENRICHMENT ( S.I.C.E.)
Some universities have suggested that CO2 levels be enriched 20-30 minutes
after lights have turned ON. This allows plant’s stomata to open and the plant
to begin respiration prior to CO2 enrichment. CO2 can also be turned OFF
20-30 minutes (even more) prior to the lights actually turning off. This allows
the garden to use up the elevated CO levels prior the dark period. Both of these
are possible with the Sentinel CPPM-4i. Individual greenhouses and gardens
will vary. Please proceed at your own risk/discretion.

TheSentinelCPPM-4ihasbeendesignedwiththemostadvanced“TrueFuzzyLogic”
programming and componentry for optimal use with CO2 regulator / bottled CO2
pairings. While many CO2 brands claim to use fuzzy logic, they are really using a
less advance PID control loop design. Sentinel “True Fuzzy Logic” ensures the most
precise control and enrichment levels available to bottled CO2 regulator users.
For best results, Sentinel recommends using the highest
quality Sentinel CO2-REG components.

Recalibration of the CO2 sensor:
Recalibration of CO2 sensor is required at 12 month intervals, after the probe being
jarred/sustaining rough handling, or other times if CO2 levels do not appear to be
reading accurately. Recalibration of the CO2 sensor is a fairly simple process,
provided that basic protocols are followed:
1. Move the remote sensor to an area outside of the garden or greenhouse that is in
freshair-preferablyoutdoors.Thesensormustbeawayfrompeopleandother
CO2 generation sources. Protect unit from direct sunlight.
2. TurnthepowerontotheCPPM-4i.Allowtheunittooperateundisturbedfora
minimum of 30 minutes with a time of 1+ hours being optimal.
3. Press the CO2 Calibrate button on the main controller. Set the desired ambient
(baseline) CO2 levels using the UP/DOWN arrows. Normally, this will be 400ppm.
In larger cities or more congested areas, settings up to 450ppm may be used.
Press the ENTER button to confirm your selection.
4. Leave the area and keep people or other CO2 generation sources away from the
unit for a minimum of 15 minutes.
5. ReturntheCPPM-4itoyourgardenorgreenhouse.
Annual Battery Replacement:
Forcontinuedoptimalperformance,itisrecommendedthatthebatteryfortheCPPM-4i
be replaced on an annual basis. Use of a high quality CR 2025 button cell battery is
required. Please follow proper local disposal procedures for your discarded battery.
