or
(*) Starts -12°F below setpoint, stops -6°F below setpoint
to avoid Fan and Heater to compete

6 FACTORY SETTING ALTERNATE SETTING
LOW
TEMPERATURE
LIMIT While using fan to cool & dehumidify, it stops the fan
if temperature reaches 6°F below setpoint even if it
is still too humid, to avoid freezing the crop. Limit
resets when temperature reaches setpoint. While using fan to cool & dehumidify, it stops the fan
if temperature reaches 10°F below setpoint even if it
is still too humid, to avoid freezing the crop. Limit
resets when temperature reaches setpoint.
7 FACTORY SETTING ALTERNATE SETTING
HIGH
TEMPERATURE
LIMIT Relative to setpoint Temperature Limit:
While injecting CO2, CO2 output is stopped if the
temperature reaches 10°F above setpoint because of
excessive burner heat, then fan will restart
immediately. Limit resets when temperature reaches
setpoint. Absolute Temperature Limit:
While injecting CO2, CO2 output is stopped if the
temperature reaches 90°F because of excessive burner
heat, then fan will restart immediately. Limit resets
when temperature reaches setpoint.

PRIORITY
MANAGEMENT
(3 alternate settings)
The CO2 Output has a higher priority than the
FAN Output. The FAN stops when the CO2 output is
ON. FAN resumes operation following a ON-
DELAY when CO2 Output turns OFF.
RESETTING THE ON_DELAY:
the ON-DELAY is reset to allow the FAN output to turn ON
immediately when CALIBRATION pushbutton is pressed during
normal operation.

The CO2 Output has a higher priority than the
FAN Output. The FAN stops when the CO2
output is ON. FAN resumes operation
immediately (NO DELAY) when CO2 Output
turns OFF.

The FAN Output has a higher priority than the
CO2 Output. The CO2 stops when the FAN
output is ON. CO2 resumes operation
immediately (NO DELAY) when FAN Output
turns OFF.

The CO2 and FAN Outputs work
independently.

FAN OUTPUT
ON-DELAY
(3 alternate settings)
The FAN Output ON-DELAY (started as soon as the
high priority CO2 output turns OFF) is 10 minutes.
RESETTING THE ON_DELAY:
the ON-DELAY is reset to allow the FAN output to turn ON
immediately when CALIBRATION pushbutton is pressed during
normal operation.
The FAN Output ON-DELAY (started as soon as the
high priority CO2 output turns OFF) is either

5 minutes.

20 minutes.
