About this item

• 【Universal Wireless Remote Control】 From simple main remote control to autonomous control such as windows, entrance, garage doors, alarm system, lifting devices, light, rolling door

• 【High sensitivity】433Mhz wireless remote control can pass through walls, floors and doors at a reliable distance. Maximum signal range is up to 164ft/50m with no obstacle,The receiver is suitable for DC 6V~30V voltage, so both DC12V and DC24V is OK. It is more flexible to use.

• 【Stable and Reliable】With high reception sensitivity (> - 105dBm), the 2 remote control switches adopt wireless coding technique, non-directional switch, do not disturb each other. It can be used with the remote control to switch between momentary/toggle/latched 3 working modes

• 【Intelligent Learning Mechanism】Learning Code provides high security due to low repetition rate and re-learning mode, which allows you to erase the old code and re-learn a new code when a remote is lost.

Operation Introduction:

About Working Mode:
1. Momentary/Joggle: Press and hold->On; Release->Off
Keep pressing one button, the corresponding channel is working /on; Release your finger is stop/OFF. (4 channel switch(receiver) need 4 button remote control (transmitter )
2. Toggle/Self-Lock: Press->On; Press again->Off
Press one button for one time, the corresponding channel is working/on; Press the same button again to stop/OFF. (4 channel switch(receiver) need 4 button remote control (transmitter).
3. Latched/Inter-Lock: Press->on; Press other button->Off
Press one button for one time, the corresponding channel is working/on; Press another button is stop/OFF(At the same time, another corresponding channel works). (4 channel switch( receiver) need 4 buttons remote control (transmitter).

The Setting of Working Mode:

1.Momentary Mode: Pressing the learning key button on the receiver board once (LED Indicator on receiver board will signaling simultaneously), then press any of the remote button, signaling three times by remote's LED indicator means setting Momentary Mode successfully.

2. Toggle Mode: Pressing two times the learning key button on the receiver board twice(LED Indicator on receiver board will signaling simultaneously),then press any of the remote button , signaling three times by remote's LED means setting Toggle Mode successfully.

3.Latched Mode: Pressing the learning key button on the receiver board three times (LED Indicator on receiver board will signaling simultaneously), then press first remote button, follow on second remote button, signaling three times by remote's LED indicator means setting Latching Mode successfully (first button stands for on, second button stands for off ).

4.2CH Momentary + 2CH Toggle: Pressing the learning key button on the receiver board four times(LED Indicator on receiver board will signaling simultaneously),then press any of the remote button , signaling three times by remote's LED indicator means setting successfully.

5. 2CH Momentary + 2CH Latched: Pressing the learning key button on the receiver board five times(LED Indicator on receiver board will signaling simultaneously), then press any of the remote button, signaling three times by remote's LED indicator means setting successfully .

6. 2CH Toggle + 2CH Latched: Pressing the learning key button on the receiver board six times(LED Indicator on receiver board will signaling simultaneously), then press any of the remote button, signaling three times by remote's LED indicator means setting successfully.

7. 2CH Latching + 2CH Latched: Pressing the learning key button on the receiver board seven times(LED Indicator on receiver board will signaling simultaneously), then press any of the remote button, signaling three times by remote's LED indicator means setting successfully.

8. Deleting Existing Remote Controls Data: Pressing the learning key button on the receiver board eight times, the LED Indicator on receiver board will flash for eight times, it means that the existing remote controls are deleted successfully.
