Display Module

Green

No buzzing

The unit is operating properly, or there is a warning.

Yellow

Intermittent buzzing

There is an unacknowledged major alarm.

Red

Constant buzzing

There is an unacknowledged critical alarm.

Note: Hold down the SW button on the main control module for about 1s. In all the preceding states, the indicator blinks at 1 Hz (on for 0.5s and off for 0.5s).

Single unit control

Each unit has an independent control system to ensure normal and high-precision operation.

Operations

Users can set parameters and query status on the 7-inch true-color touchscreen.

Four remote functions

The module supports the four remote functions when it connects to the NMS.

• Telemetry: measures the supply air temperature, return air temperature, supply air humidity, return air humidity, and working status of the unit.
• Teleadjust: adjusts the temperature, humidity, and alarm threshold.
• Teleindication: generates alarms for the startup/shutdown, overvoltage/undervoltage, high/low return air temperature, high/low return air humidity, air filter normal/blocked, and fan normal/faulty state.
• Telecontrol: controls startup/shutdown.

Teamwork

Remote management

Users can remotely manage the operating status of one or more units.

Storage

• A large number of fault alarm records can be stored. Alarms can be managed by severity. A maximum of 500 historical alarms can be stored for each severity. That is, a maximum of 1500 historical alarms can be stored.
• The controller displays up to 30 days of temperature and humidity in colored curves. O&M personnel can view the operating status of the device onsite.

Log backtracking

Access logs can be backtracked. Up to 1000 historical operation logs recording login and setting can be stored.

Power management

Supports alarm reporting, fault diagnosis, and alarm recording for reverse phase, open phase, overvoltage, undervoltage, high frequency, and low frequency; provides functions such as automatic protection, recovery, and restart.
