Light Odometer Feature (Change Bulbs Icon):
The Hyperion
®
2 monitors the total time the lights output has been enabled.
After 4,000 hours the remote controller will show the change bulbs icon.
This is used to indicate that the grow lights may be approaching the end of
their useful life.
Alternate Exhaust Daytime/Nighttime Control:
The Hyperion
®
2 has an Alternate Exhaust mode: this mode changes how
the Hyperion
®
2 controls humidity inside the room. While the Hyperion
®
2 is
in the Alternate Exhaust mode, the Dehumidification output is deactivated
completely. Details on how to enable/disable this feature are given in
Alternate Exhaust Mode in the Checking and Adjusting the Hyperion
®
2
Settings section of this document.
Controlling RH with Alternate Exhaust Feature Enabled:
If the room’s RH rises above the RH setpoint by the amount of the
hysteresis setting (or the setpoint plus 2%), the Exhaust output will activate.
This output will remain on until the room’s RH drops below the setpoint
by the hysteresis setting (the setpoint minus 2%). There is still a separate
Daytime and Nighttime setpoint.
The Exhaust output is also activated by the temperature and CO
2
Nighttime
settings as described in Normal Daytime/Nighttime Control.
NOTE:
The CO
2
output is always defeated when the Exhaust output
is activated.
