1. Clock Calibration When the display shows the time and the current time is inconsistent, it can re-calibration. First, hold down the clock button, and then respectively, "the school weeks," "school time", "school hours" key can be transferred to the current time clock. Timing Set a, click the "regular" button, the display at the bottom left a "one open" word (for the first time you open time). And then press the "School week" Select the five-day work system, the same day, every day a different mode, and then "school time", "school hours" button, enter the desired open time; b, and then click the "timing" button, the display at the bottom left a "one off" word (for the first time closing time), and click the "school weeks", "school time", "school hours" button, enter the required closure The date and time; c, continue pressing the "regular" key, the display shown at the bottom left will be followed by "2 open, 2 closed ... ..., 10 open, 10 closed" indication, refer to the steps a, b set the subsequent opening and closing time; d, set up 10 groups a day without switch, you must click "Cancel / restore" button, the extra time to eliminate each group to "--:-- pattern displayed on the screen (not 00:00) "; e, timing is set up, should be "clock" that allows the display shows the current time; f, according to "automatic / manual key, the screen below the" ▲ "symbol from the" off "position, transferred to" automatic "position, this time, when the control switch can be set according to the time Between automatic and off the circuit. If in the course of the need for temporary opening and closing the circuit, you only need to click "Auto / Manual" key "▲" symbol transferred to the corresponding "open" or "Off" position. Example 1: A electrical power required to 19:00 every day, 8:00 the next day power outage. A, follow the steps ①, so that screen display as shown in Figure 1a. B, follow the steps ②, so that screen display as shown in Figure 1b. C, follow the steps ④, so that the subsequent Group "2 open, 2 closed ... ..., 10 open, 10 closed the time displayed on the screen as "--:--"。 D, repeatedly press the "regular" key, check whether the switching time of each group required the same, if not correct, but also to repeat the steps AC. E, follow the steps e, f the "▲" symbol transferred to "automatic" position. 3, rain light-control probe to use ①, insert light control without probe and rain control probe, the timer switch to set the action only in accordance with timing. ②, light-control use: plug in the light-control probe (at the top of the light-control jack on the bottom for the rain-control jack) and, if light, switch off about a minute or so; no illumination, about About five minutes to restore the status quo ante identification switched on-off illumination is generally 25LX ± 5LX. ③, rain control use: plug in the rain-controlled probe, such as the probe sensor to the rain, switch off immediately, no rain for about five minutes after the identification of restitution connected, power resistor 50KΩ, electricity resistance 1MΩ. ④, light control and stormwater control at the same time use: the same time, plug in light control, rain-control probe, in a light rain, or any kind of state, the timer switches off; such as light and rain are not, time switch according to the original setting program works. ⑤, rain, light control two kinds of control functions, are required to be transferred when the control switch in the "automatic" or "open" position can only work."Troubleshooting: 1, if the off time of a day in the open did not open, or opened after the time off not to pass, it is probably because from time to time set up "a week" did not transfer right, please follow the "timing settings" method described in inspection or re-tune. 2, if the confirmation "open" and "off" time adjustment was entirely correct. However, this switch should not have the time to open open up, or should not be closed when they were turned off, it may be because of the extra sets of switching time has not been eliminated, please refer to "Timer Settings" in the way described in the elimination (Note: Switching the time display "--:--" made it apparent that the elimination, not "00:00" for elimination). 3, if all of the above two is correct, and this switch is still movement is not normal, there may be "automatic / manual" key to be artificially moves, check the "open, automatic, off" sign "▲", change it from "off" Position transferred to automatic position. 4, as are several ways to use the above failures can not be excluded, please contact the company or the local dealer handled.
