The program group is one group, which can be turned on for 1 second and closed for 1 second, so the infinite second control cycle. Arbitrary control of time countdown and cycle within 23 hours 59 minutes 59 seconds

Function example: Cycle function If you can set the "light" to turn on for 1 second / stop for 1 second, the infinite loop works continuously. You can also set the "light" to work for an infinite cycle without stopping for 1 second / stop for 1 hour. The opening time can be adjusted from 1 second to 99 hours 59 minutes and 59 seconds, and the stopping time can be adjusted from 1 second to 99 hours 59 minutes and 59 seconds. Countdown function For example, set "light" to turn off after 30 seconds. After the time is up and the machine is powered off and stopped, pre Start to repeat the last set time of 30 seconds. No need to repeat settings, simple and practical. Directly control the electric power within 2200 watts. Please pay attention to pump motor products. The starting current of the motor is 5-8 times the rated power of the product. The motor is directly controlled within 300 watts, and the AC contactor is required if it exceeds. AC is configured by motor power. Contact customer service for details. Microcomputer , liquid crystal display, accurate travel time, simple operation, high precision, industrial grade, strong anti-interference .

Built-in , no need to reset the program in case of power fai (the battery is used to memorize the machine program, not to power the machine). Small, multi-functional, lightweight and compact, easier to install. Dimensions (60x60x32mm)

[Scope of application]: Microcomputer time control switch, single and double countdown, second control, cycle countdown This product has a novel design and is a widely used power switch control device. The single countdown function is suitable for aperiodic switching control. The cyclic countdown function is suitable for periodic switch control or as a time relay. Suitable for industrial drying, aging, drying, ventilation, flushing, irrigation, street lights, advertising lights, neon lights and other equipment. Applicable to electric water heaters, heaters, water dispensers, electric vehicle charging and electric fans for household appliances. Aeration equipment such as fish tanks and fish ponds, spraying and humidifying equipment such as fountains, gardens and nurseries.

Precautions: 1. In order to prevent electric shock and heat generation under strong current, the product is used for electrical appliances and power supply with firm contact. 2. The input line of this switch can only be connected to the specified voltage power supply (the voltage of the machine is based on the back mark, do not look at the manual, the manual is a general type for operating instructions only). Do not connect it to other power sources. The damage of the wrong wiring is not a quality problem (if special specifications voltage is required, please order). 3. Do not use this control switch for equipment (such as equipment and large-scale equipment) that may cause life-related accidents or have a significant impact on society due to the error of the time control switch. 4. The switch should be operated in an environment free from humidity, corrosion and heavy metal content. Do not contaminate with oil or water. 5. The usage period of this timer is one year. If there is a quality problem within one year, it can be replaced or repaired free of charge (excluding disaembly of parts by itself). Please read the manual before installing and using the product. Keep it for future use. 6. If the controller enters 24VDC, do not connect to 220V AC 7. When filling the order, please indicate the incoming line voltage; DC12V, DC24V, AC220V.

Wiring diagram description: 1. The "switch" is a switch that is not connected to the "power" at the "power" and only controls one live wire. 2. The timer has no voltage-transforming effect, and cannot input DC12V and output AC220V. The timer has only input (supply voltage) and no output. Not a common type of binary input timer. The new wiring method can control non-current lines such as telephone lines. 3. It can control different voltage from "power source", such as DC12V power supply, but control on / off of one line of AC220V line of external power supply. 4. When not working, the switch is off and current cannot flow. Friends who can supply power to the machine at any voltage will note how much voltage (usually the electricity used at home is AC220V)

Instructions 1. Before use, please pre the "C" key or pre and hold the "Start / Reset" key to reset. The display shows "0: 00: 00" and flashes. 2. Pre the "Second", "Hour", and "Minute" keys respectively to set the countdown off time. 3. After preing the "Set" key, pre the "Second", "Hour", and "Minute" keys again to set the countdown off time. 4 After the time setting is completed, pre the "Start / Reset" key again, the switch starts the countdown work, and the product works in a cycle of "on-off-on".
