1. Open battery compartment located on bottom of unit. Remove the plastic protection
tab from underneath the battery. Replace battery compartment cover
2. Mount supplied bracket to wall
3. Slide unit onto bracket
4. Secure unit to bracket with supplied set screws
5. Connect one end of supplied S.I.C.E. shielded communications cable to unit.
Route cable as needed. Connect other end of S.I.C.E. cable to the remote sensor
in the desired location.
6. Make sure power switch is in the “OFF” position. Connect power cable to unit.
7. Plug power cable into appropriate receptacle. A timer or other device should not be used.
8. Turn power switch to the “ON” position
9. Upon initial power up, and subsequent re-starts, the unit will take 2-5 minutes to
warm up, stabilize the CO2 sensor and begin operation. This is normal.
10. Set the current time. This is done by pressing and holding the “Set Clock” button for
5 seconds. Make sure to press the enter button after every value to save the settings
into memory.
11. Set the CO2 on / off time. This is done by pressing the “CO2 ON/OFF TIME” button.
The CO2 ON time should coincide with the lights ON cycle or daytime. The CO2 OFF
time should coincide with the lights OFF cycle or night time. Make sure to press the
enter button after every value to save the settings into memory.
For 24 hour ON light cycles, set the CO2 ON AND OFF times to 10:00 and 10:00. This
will allow for continuous CO2 control and enrichment.
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.
