ST43 S Unit Smart Remote Control Manual

Three working modes for smart control to ST43 solar street light

Various working modes are achievable by adjusting the setting of Smart-Unit. There are three modes for smart streetlight function, D2D mode, Five-stage Night mode, and T0Tmode. But we should note that the motion sensing function is only work in ‘Five-stage mode’ and ‘ToT’ mode. ‘DelayOff’ and ‘Dim NP’ work in ‘Time3’ and ‘Time4’ period.

D2D mode

D2D mode means the solar street light keeping on from dusk to dawn without induction function. Motions sensing function is not available in this mode. Set ‘Time1’ to this mode, and solar street light will work in dusk to dawn mode. In this mode, light level keeps the same from dusk to dawn.

Five-stage Night mode

The five stage mode means that are five time periods to light up and the timing throughout the night. There are five stages complected before the light is off. You can set Time1-5 and Dim 1-5 with Smart-Unit in this mode.

T0T mode

T0T mode is similar to five-stage night mode. If the fourth stage of five-stage mode is set to T0T, the working mode is called T0T mode. The key feature of T0T mode is the duration of the fourth mode (T0T mode) is related to the length of the night. The night time is changed with reasons rolling on. The night time in the winter is longer than summer, thus duration of the fourth stage in the winter will be longer, while the duration of the other stages remains.

Smart-units comes with default setting mode. It can work with ST43 solar street light perfectly, providing sufficient lighting to ensure safety as well as saving energy.

The default setting mode is as followed:

Time1: 1.0H/100% ; Time2: 2.0H/80% ; Time3: 3.0H/60% ; Time4: T0T/40% ; Time5: 2.0H/100%

DelayOff: 10s ; Dim NP: 10%

The controller works as follows：

After the arrival of the evening the first time the load is lit for 1 hour (full power 100%), the second time the load is lit for 2 hours (power 80%), the third time load light for 3 hours (when people are near the lamp then the load is 60% light, when people are away from the lamp the load is 60% * 10% light), and then the controller according to the actual night time automatically calculate the length of the fourth paragraph (when people are near the lamp then the load is 40% light, when people are away from the lamp the load is 40% * 10% light), the fifth time load light 2 hours (full power 100%).
