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

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
