Controller parameter 1, working voltage: AC85-240V 60HZ/50HZ2, working frequency: 433.92MHZ3, the total load power: <1000W4, receiving sensitivity: -108dBM5, working method: wirele remote control6, coding method: learning code7, modulation method: ASK8, working temperature: -10 deg C ~ +70 deg C9, size: 72 * 38 * 26 (mm) Wirele switch parameters: 1, working voltage: DC 3V2, working frequency: 433.92MHZ3. Transmitting power: <10mW4. Remote control distance: <100 meters (indoor distance)5, working method: wirele remote control6, coding method: learning code7, modulation method: ASK8, working temperature: -10 deg C ~ +70 deg C9, size: 86 * 86 * (mm)10.standard battery,Cr2032 battery, ((Does not contain battery)) How to pair signal 1. Pre and hold the controller for 3 seconds to enter the code matching mode (the code indicator light flashes 5 times).At this time, pre the wirele switch 1 times and wait for 2 seconds. The code is succeful (the default is always on); How to clear the signal Pre and hold the controller for 10 seconds to clear the code (the code indicator flashes 10 times); Our advantage: 1.First suggest watching the video in the link, you can better understand the product2. Pa CE, FCC, ROHS certification: 100% inspection before transportation to ensure product safety3. Night fluorescent function, multiple combinations (free pairing signal), remote remote control4.Profeional after-sales team: Shoot a large number of videos to handle various anomalies and quickly solve customer problem We recommend multiple products to buy, more convenient at home Controlling 1 lamp from multiple place Working principle Input and output intermediate acce controller. Wirele switch control current is turned off and on at 433 MHz Avoid Darkne and Save Energy Turn the lights on in advance to avoid darkne. Turn off the lights after leaving, save energy Remote control distance100m Can control 1 light from 15 different positions Luminous fluorescent strip Middle of the night, do not worry about finding the switch Low power consumption,Battery used for about 1 year Cr2032 battery, standard battery, easy to replace (Does not contain battery) Paed CE, fcc ,RoHs certification, note: 1. profeional electrician should operate this product. When powering on, do not touch the antenna. Install this product without opening the protective cover2.This controller will not be available if a wall switch with RF function is installed at home. Otherwise the function will be affected. Just need to buy a separate wirele switch3. Do not operate with power. Turn off the power supply and operate it. If the test is confirmed to be correct, use it under the guidance of a profeional electrician.4. When the voltage of the remote control is insufficient, please change the battery in time (the remote control distance becomes closer when the remote control battery voltage is insufficient).5. When using wirele electronic products, care should be taken to avoid metal masks, large electronic devices, electromagnetic fields, etc., which have strong interference sources, to avoid remote control and short receiving distance or to work normally.6. Do not use this electronic product abnormally. Abnormal use will reduce product performance and longevity. In severe cases, damage to the product will also pose a safety hazard.
