• Temp setting: The desired temperature of the discharge air.
Note: If setting the control mode to Return Air, this setting becomes "Return Air Temp."
• Temp control band: It is recommended to leave this at the default setting of 5.4°F (3.0°C) except for low-load situations.
If the IT load is less than the In-Row Cooler minimum capacity or if the IT load often changes, set a higher band to keep
the room temperature stable. A higher band can help reduce the number of compressor on/off cycles. For this, the
recommended setting is 5.4° to 10°F (3° to 6°C).
If the IT load is greater than the In-Row Cooler minimum capacity or if the room IT load is stable, consider setting the band
to its default or even lower to optimize temperature precision. Recommended setting: 3.6° to 5.4°F (2° to 3°C).
• Humidity setting: The target relative humidity of the dehumidification system.
Note: the In-Row Cooler cannot add humidity to the air.
• Upper humid control band: The allowable range above the humidity setting. For example, a delta of 20% RH at a humidity
setting of 50% RH would mean the dehumidification cycle would initiate when the humidity rises above 70% RH.
• High/low temp alarm band: If the discharge temperature exceeds/falls below this value, an alarm is triggered.
Note: 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.
• Enable maintenance: Allows the ability to engage Maintenance Mode from the home screen.
Note: this allows Maintenance Mode to be engaged from the home screen without a password.
• Maintenance running time: Maintenance Mode duration. If the user does not turn off Maintenance Mode from the home
screen, the In-Row Cooler will automatically revert to normal operation after this time.
