Setting Method:

First time use the timer switch,pls input AC and let battery recharge, after then press reset key.

Adjust Clock:

Press the key "clock",meanwhile ,press the key"hour","minute"and"day" espectively to adjust hour,minute and day to accord with the current clock.

Timer setting:

step1  press the key "prog". Enter the first group of timing on (display1οΝ).

step2  press the key "day”.  Setting the day of switch-on time (everyday,5-          days,6-days,everday different etc.)

step3  press the key "hour"and"min".Setting switch-off time (hour ,minute)

step4  press the key"prog". Enter the first group pg timing off (dispaly 1off)

step5  press the key "day". Setting the day of switch-off time (everday,5-          days,6-days.everyday different etc.) Pay attention that the day of switch-off time must correspond to the day of switch-on time.

step6  press the key "hour" and"min".Setting switch -off time (hour,minute)

step7  repeat step1 to 6  setting 2 to 10 groups of on-off time. If there is no need to set 10groups of on-off ,press the key of "rst/rcl" to clear the rest groups of on-off time to"-:-"(but not 00:00)

step8 press the key "prog" repeatedly. check whether every group of on-off time is correct;press the key "cnl/rst" and repeat step 2 to 7 in case of error.

step9 press the key "auto/manu". adjust on-off sign to the current state ("on" or "off") and adjust to the position of "auto".

step10  press the key “clock”. end timing state and enter the state of clock display.

Connection Method

1. the connection of 1a

The product has 1 normally open contact. The connection is showed as fig. 1.

2.the connection of 1c

The product has 1 normally open contact and 1 normally closed contact. the connection is showed as fig.2.

3. the connection for directly controlling single phase

The power of controlled electric should be supplied by single-phase ,and the power consumption is no more than the switch's rating capacity(resistance load 25A,sensibility load 15A). The connection is showed as fig.3.

4 the connection for three phase

 The power of controlled electric should be supplied by three phase. It need to connect to three-phase relay whose coil voltage is AC220V/50HZ. the connection is showed as fig.4.
