CONTROLLER

3. OUTLINE OF FUNCTIONS

This wire controller provides the

following functions:

Basic conditions of operating the
wire controller

1. Applicable range of supply voltage:
Input voltage is AC 220V±10%, powered
to wire controller by attached power
adapter.

2. Operating environment temperature
of wire controller: -15℃~+43℃.

and E(reserved).Connect with other wire controllers through the terminals P, Q and E.

2. Set the action mode through the keypad operation.

3. Provide the LCD display function.

4. Provide the timing startup function.

5. Real-time clock function (the wire controller inner place 3V battery )

When the wire controller is powered on, the LCD will display the current time; if it is

ture. Temperature range is not same in

different operation mode .

3.Temperature range depend on outdoor

unit .

●

Operation procudeure of system

ON/OFF

Press [ON/OFF] button, running indicator

of wire controller is light, unit is start to

run, and display running status at wire

controller. Press this button once again,

unit will stop running.

●Operation procudeure of system
information querying

1.Press [QUERY] ,enter Check status.

2.Press [ADDRESS/+] or [ADDRESS/-]

button, select the unit you want to query.

3.Press [PAGEUP] or [PAGEDOWN]

button to query the unit information, which

includes E-, P-, Tou, Tin, T4,T3A, T3b ,IA,

Ib, T6, FA, Fb or T3A, P-, E-,Tout, Ib, IA,

Ts, T4, T3B.

●Operation of remote on/off

If the main unit’s is under the remote
on/off control, Net-ON

flashes, and

communicate with upper unit is invalid.

●Operation procudeure of
HYSTERESIS TEMP.SET(δ )

1:Through the hysteresis setting, the

system can adjust the load effectively.

2:The adjusting logic of cooling mode :

11

(the parameter of δ1,δ2,Tj1 and Tj2 are

decided by the outdoor unit)

3: The adjusting logic of heating mode:
(the parameter of δ1,δ2,Tj1 and Tj2

are decided by the outdoor unit)

(TAL: total outlet water temperature)

● Fault alarm handing

1:When unit fails or the wire controller

detects failure of communication with the

the outdoor units, the indicator blinks.

After all fault of the system and the wire

controller are eliminated, the indicator

stops blinking. The fault indicator and

1.Before power failure of the heating

water system or wire controller, the wire

controller memorizes the status of the

unit automatically, and sets the water

temperature value except timing on/off

function. After being powered on, the

wire controller will send the relevant

signals to the heating water system

according to memorized status before

power failure, in order to ensure that the

unit can run in the originally set status

after restoration of the power supply.

2. In the normal status,the background

light is off.Press any key can only turn
on the background light .

3. In order to protect the equipments, it

is not allowed to change the running

mode quickly or frequently. It should

operate the wire controller to start up the

unit after 3 minutes later or all units are

shutdown.

4. The wire controller and the outdoor

unit must connect with the same power

supply, powered up and powered off

simultaneously. It is not allowed to cut off

the power supply separately.

5. When several wire-controllers are

parallel connected, the timing message

can not communicating in these

wire-controllers, and the timing will work

separately. In order not to confuse, we

suggest set the timing message on one

wire-controller for the reason of indoor

unit performance is compliance with the

sequence of setting time.

6.During changing or installing the

battery, pay attention to the “+”,“-” poles

of the battery and install it correctly, or

will damage the control panel or battery,

even worse will put lives at risk.
