Settings

. Load Control Settings

1. Dusk to Dawn

When solar module voltage goes below the point of NTTV (Night Time Threshold Voltage) at sunset, the controller will recognize the starting voltage and turn on the load after 10 minutes delay. When solar module voltage goes above point of DTTV (Day Time Threshold Voltage), the solar controller will recognize the starting voltage and turn off the load after 10 minutes delay.

2. Light ON + Timer

When solar module voltage goes below the point of NTTV (Night Time Threshold Voltage) at sunset; the solar controller will recognize the starting voltage and turn on the load after 10 minutes delay. The load will be on for several hours which users set through LED digital tube. The controller has dual timer function. Please refer to table 4-5 ―Load Work Mode Setting‖.

3. Test mode

This mode is the same as Dusk to Dawn. But there is no 10 minutes delay when controller recognizes the starting voltage. When below the starting voltage, the controller will turn on the load, if higher, it will turn off load.

The test mode makes it easy to check the system installation.

4. ON/OFF modeThis mode is to turn ON and OFF the load by manual.

A.Load Work Mode Setting

When the led digital tube is not display, Press the setting button "Key" more than 5 seconds , and keep on press it once more,led digital tube will be changed once amng

B.Work mode led digital tube display：

Press the setting button "KEY" more than 5 secondsand setting indicators will be changed once among 【0】【b1】【J0】【S0】【F0】【H0】【q0】【8.8.】.

When you want to change`s setting indicator is on, press the setting button for more than 5 seconds till the LED digital tube flashes. Then press the setting button till the desired number appears according to the following table. The setting is finished when the digital tube stop flashing.
