Setting Description Notes
Temp Setting The desired temperature of the discharge air. If setting the control mode to Return Air,
this setting becomes "Return Air Temp."
Humidity Setting The target relative humidity of the dehumidification
system.
The cooler cannot add humidity to the air.
High Temp Alarm Band If the discharge temperature goes below this value, an
alarm is triggered.
If setting Control Mode to Return Air, you
MUST ADJUST this setting to be based off
of the return air temperature instead.
High Humid Alarm
Band
If the return air humidity exceeds the humidity setting
+ the high humid band setting, an alarm is triggered.
For example, if the user humidity setting is 50% and
the user wants the high humidity alarm to trigger
at 80% RH, set this to 30%. If dehumidification
mode is enabled, a high-humidity alarm will engage
dehumidification mode.
Restart Delay Time Restart delay after restoring power. If power is lost,
the cooler will automatically restart after this delay
time.
Control Mode: Supply
Air (Default)
The cooling control strategy will be based off
the temperature of the discharge air. Return air:
The cooling control strategy will be based off the
temperature of the entering air.
If the load is lower than 30% of rated
cooling capacity, which may cause
frequent cooler on/off cycling, it is
recommended to set Control Mode to
"Return Air." Otherwise, set Control Mode
to "Supply Air."
Enable Maintenance Allows the ability to engage Maintenance Mode from
the homepage.
This allows Maintenance Mode to be
