My company design and manufacture of this section of the wireless receiver controller and the three-button remote control is a complete set of wireless digital intelligent remote control components, mainly used in the control of AC motor positive and negative (such as: projection screen, electric curtains, electric hanger , Garage doors, retractable doors, etc.), can be used to control the device to achieve the motor is positive, reverse, or switch on and off, to achieve wired and wireless compatible. The receiving controller with high security, large storage capacity, stable performance and low power consumption, and easy to use, without the use of traditional jumpers or DIP switch coding, just the remote control to send the wireless signal to the receiving control Receiver and storage can be used to achieve supporting. Each receiving controller can store multiple transmitters (remote control). If the learned remote control is lost in use, only the information stored in the receiving controller needs to be cleared and the lost remote control can not Receiving the controller for remote control, to regain the right to use, must be re-learned by the owner once to use, so as not only to avoid the owner when the loss of the remote control concerns, but also for the addition of a new remote control provides a convenient. Second, technical indicators: 1, working voltage: AC220 10% 2, the load power: 500W 3, the working frequency: 315MHz (default), 433MHz optional 4, working temperature: -25 ~ +75 5, remote control distance: 100 meters (open area) Third, the use of methods 1, the code: Open the receiver panel, connected to the power and then hold down the learning key (set key) hold, then the light starts flashing, release the learning key Press and hold any key on the remote control, indicating off, indicating that the success of learning . (After learning, press the up button or down button on the remote control to hear the sound of the relay beeping.) Otherwise, please re-learn. 2, Wiring: Please follow the circuit board marked on the power cord and the control line. Remote control and control panel keys role: key: roll up; = key: stop, power-off; key: scroll down Fourth, matters needing attention 1, the floor charged, do not touch after power 2, if installed after the motor does not work exchangeable direction of a try Note: 433mhz and 315 mhz are available ,315mhz will be sent out if there is no demand on frequency Package Included: A: 3 x Receiver 2 x Transmitter (with battery) B: 4 x Receiver 2 x Transmitter (with battery)
