The NE Series Command Center (Figure 9) is
the brains behind the NE Series
Dehumidification System. The Command
Center is composed of a microcontroller
system, an LCD display and keypad, an
Ethernet interface, and WebSentry – a web
browser based remote interface tool for
monitoring and controlling NE Series systems
from anywhere in the world via the internet

satisfied.
A/C Solid Green indicates system is
in air-conditioning mode. Compressor
will run when anti-short cycle timer is
satisfied.
Pool Solid Green indicates that pool
heating is on. If Dehum or A/C is also

sensor information, view unit operating status,
change setpoints (password protected), adjust
the occupied/unoccupied schedule (password
protected), and view alarms and warnings.
The system operates automatically.
In Service Mode, the trained technician has
access to special features to aid in system
commissioning and troubleshooting, including
Ethernet network access test utilities.
The system operates under manual control.
