Parameter

Explanation

Input

0 = No condensate present.
1 = Condensate present.

Pump

0 = Condensate pump not active.
1 = Condensate pump active.

Cycles

Operating cycles of condensate pump.

Duration

Last duty cycle of condensate pump.

Status

Current status of condensate monitoring.
"Off": The pump is not running.
"On": The pump is running.

Note:
Condensate sensors and condensate 
pumps are not installed in the factory.

Parameter

Explanation

Command

Select the operating mode.
"Automatic": Fan speeds are determined 
and automatically regulated according to 
the server outlet temperature.
"Manual": Fan speeds are set manually.
"Off": Fans are deactivated.
"Minimum": Fans rotate at the preset min-
imum speed.
"Full": Fans rotate at 100%.
