NONE (Disabled at Night)
CO2 EMPTY TANK DETECTION:
The SCC1 is able to detect a defective CO2 enrichment period, during which the CO2 PPM level never builds up.
The SCC1 will declare a “CO2 Empty Tank” fault in two conditions:
Condition 1: High Temp limit has been reached twice in a row while CO2 PPM remains low.
When the High Temp Limit is reached while the CO2 level is still low (below setpoint –200 ppm), the SCC1 assumes the CO2 tank is
empty (CO2 tank or propane/natural gas burner tank); if this condition is met at the end of two consecutive “enrichment” cycles, the
SCC1 will declare an empty tank condition.
Condition 2: a 30-minute time has elapsed while CO2 PPM remains low.
The second method is time based. If the CO2 output is ON for 30 minute and the CO2 PPM level is still low after this delay, the SCC1
will also declare an empty tank condition.
Effect of CO2 Output:
When an empty tank condition is met, the SCC1 will DISABLE the CO2 Output and the CO2 Output indicator will flash as long as this
condition is present.
Resetting the Empty Tank Condition:
CLICK the CALIBRATION button to reset this fault. However the fault will appear again if the tank has not been refilled.
The condition will reset automatically if the CO2 PPM level rises in the room up to the CO2 setpoint and every morning when the lights
turn ON to allow the controller to validate whether the tank has been replaced or not.

5- OUTPUT PRIORITIES AND FAIL STATES
Every CONTROL ACTION taken by the SCC1 is given a priority level. A higher priority action WILL ALWAYS
SUPERSEDE any lower priority action. Output Priorities can be modified with the Alternate Settings.
See Section 6- on next page.

CO2 OUTPUT
GIVING CO2 OUTPUT
PRIORITY
OVER FAN OUTPUT
ONLY FAN OUTPUT IS AFFECTED:
The FAN Output is turned OFF when the CO2 Output is turned ON to avoid wasting CO2 outside.
FAN Output resumes operation after a 10-min delay following the CO2 enrichment (timer starts when CO2
Output is turned Off). This delay allows plants to absorb the injected CO2 before re-starting the cooling FAN.
IMPORTANT NOTICE: The CO2 Output priority is suspended while the Output Indicator is flashing during
2 conditions: 1- the High Temp limit has been reached, 2- the Empty tank condition has been met. Refer to
Section 2D of the Quick Start User Guide for further details.
HIGH
TEMPERATURE
LIMITS
LOW TEMPERATURE LIMIT
ONLY FAN OUTPUT IS AFFECTED:
The FAN Output is turned OFF in the “Cooling and Dehumidifying” mode when fan is unable to reach the
HUMIDITY SETPOINT while room temperature is getting too cold.
The Low Temperature Limit is set to 6°F below TEMPERATURE SETPOINT.
Using “Cooling and Dehumidifying” mode is NOT RECOMMENDED when outside air is cold and humid, so
cooling action is possible but dehumidifying action is impossible.
HIGH TEMPERATURE LIMIT
ONLY CO2 OUTPUT IS AFFECTED:
The CO2 Output is turned OFF whenever the temperature gets too high while using a burner that generates
excessive heat in the room. Since CO2 Output is given priority over the Fan Output, the fan will always be OFF
while the burner is ON. If your burner is oversized, high temperature condition (10°F above TEMPERATURE
SETPOINT) is likely to occur. If using a tank, the high temperature limit is not likely to be reached, UNLESS
YOUR TANK IS EMPTY.

FAILURES
TEMPERATURE SENSOR
FAILURE
FAN OUTPUT IS AFFECTED:
The FAN Output is maintained ON if a temperature sensor failure is detected (damaged, short-circuited or
disconnected). This ensures a proper ventilation at all times.
HEATER OUTPUT IS AFFECTED:
The HEATER Output is maintained OFF if a temperature sensor failure is detected (damaged, short-circuited or
disconnected).
CO2 OUTPUT IS AFFECTED:
The CO2 Output is maintained OFF if a temperature sensor failure is detected (damaged, short-circuited or
disconnected). (To enable CO2 Output while Temp Sensor Falure, use alternate setting)
HUMIDITY SENSOR
FAILURE
HUMIDITY OUTPUT IS AFFECTED:
The HUMIDITY Output is maintained OFF if a humidity sensor failure is detected (damaged, short-circuited or
disconnected).
FAN OUTPUT IS AFFECTED if Slide Switch set to “Cool & Dehumidify”:
The FAN Output will keep working in Cooling mode ONLY. This ensures a proper ventilation at all times.
CO2 SENSOR FAILURE
ONLY CO2 OUTPUT IS AFFECTED:
The CO2 Output is maintained OFF if a CO2 sensor failure is detected (sensor not responding or responds with
a value below 250 ppm). This is a factory setting.
Note: in case of a LIGHT SENSOR FAILURE, the SCC1 is likely to detect a NIGHT at all times, so DAY operation will be
disable.

6- FACTORY SETTINGS AND ALTERNATE SETTINGS
When shipped from the factory, the SCC1 is set with factory settings. These settings are those that a vast majority
of users will be using during their growing experiences. Advanced users may need to change some settings in order
to fix control problems or to improve control performances in some specific set-ups.
Review below the settings that can be changed by the users.
To make these changes, refer to section below: ACCESSING THE FACTORY / ALTERNATE SETTING

Day Enrichment Knob to CAL
Lock/Unlock Slide Switch to UNLOCK
HOLD pushbutton
...BUT YOU HAVE TO ABORT the Calibration AFTER 5 SECONDS (one blink per second)
by moving the Slide Switch back to the LOCK position. Then let the pushbutton go.
Step 2 - You are now given access to the FACTORY / ALTERNATE SETTING EDIT MODE.
TO EXIT this mode, simply return the Slide Switch to UNLOCK position.

Step 4 - Understanding the FACTORY / ALTERNATE SETTING EDIT MODE
In this mode, the KNOBS and LED INDICATORS take other meanings:
Day Temperature Knob: to select the PARAMETER (among 3).
Temperature Indicators: to indicate the selected PARAMETER.
Pushbutton: to select the right setting (up to 6 settings per PARAMETER)
Day Humidity Knob: to change the setting values.
Humidity and CO2 Indicators (A to F): to indicate the setting values.
Changing the CO2 ELEVATION PARAMETER
Turn the SELECT knob (Day Temperature) to position 1. The top PARAMETER indicator will lit.
