1. General Description

1.1 Control Board

Diagram 1.1 shows the control board of the environment monitoring unit. It includes one 2*16 LCD screen, four operating buttons, four working indicator lights, and one power supply switch.

Diagram 1.1 Control Board

(1) Power Switch: turn on or turn off power.

(2) LCD Display Screen:

It shows different contents under the following three status.

Operating Mode: the first line shows indoor temperature and humidity; the second line shows the real-time clock, among which the first letter “A” stand for automatic output, ”M” stand for manual output. One can directly revise DOx register to amend the output status.

Menu Mode: can select eleven menu items in sequence.

Parameter Mode: shows parameter name and parameter value. For detail, please check the NO. 3 content.

(3) Four buttons:


At operating status: press once and release the button, enter menu operation interface;

At Menu selection interface: press once to enter the selected parameter group;

At parameter status: revise, confirm and parameter page down button; a long press on the button to exit parameters and to menu interface;

At query status: select the former day’s daily record, a long press on the button to exit query and to menu interface;

▲:increasing parameter revision. Page down button for event query.

▼:decreasing parameter revision. Page up button for event query.


At parameter status: page up button; the function is oppose to PgDn operation;

At menu selection interface: press once to exit parameter status and come to operating status;

At query status: select the latter day’s daily record; at current daily record, press the button to exit query.

(4) Four Status Lamps:

PWR : power indicator; when it is bright, it shows being connected with DC48V;

Work : when the system is working, it flashes at 1HZ frequency;

TEC : when this lamp is bright, it shows the TEC air conditioner is working(cooling or heating);

Alarm : system alarm occur.

3. Operation and Parameters

Note: please don’t change the settings of parameter group 4, 5, 6, 7, otherwise it may cause channel function failure. Generally they are already set by the factory before delivery.

3.1 Start

When the Monitoring Unit is connected to power, the system self checking begins. After the checking, it will display “Success” (means normal) or “Failure”.

3.2 Enter and Exit Parameter Menu

Under the operating mode, press the button “PgDn”, the system will enter the menu mode. Diagram 3.1 shows the menu content.

Under this mode, through the buttons “▲” ”▼”, one can choose the following menu items in sequence:

0: AI Look // Analog input channel value query

1: DI Look // Digital input channel status query

2: DO Look // Digital output channel status query

3: Event Query // Daily record events query

4: AI Define // Analog input channel function definition

5: DI Define // Digital input channel function definition

6: DO Define // Digital output channel function definition

7: ZF Cal. // Analog channel Zero amplitude adjustment

8: CPar Update // System control parameters revision

9: Time Update // Time parameters revision

10: Return // Return

After choose any menu item, press “PgDn” to enter the corresponding parameter group.

Under this mode, one can directly exit menu mode by pressing the button “PgUp”.
