Operating instructions of the C331 wireless transmitter

The C331 wireless switch is a compact and versatile radio transmitter designed to control motorized

window shades. As such, it incorporates typical functions such as channel select and movement

commands (OPEN, CLOSE, STOP) into a convenient form factor suitable for flush mounting on walls.

1. Physical description of the unit

a. There are six visible buttons on the control unit, three of which are for channel selection and

the other three to transmit commands to the end device (typically a window shade motor).

b. There is a LED channel indicator on each of the channel select buttons. Pressing either the

Channel 1 or Channel 2 button will turn on their associated LED, indicating the channel has

been successfully selected and awaiting command. The third channel select button is a

special function button that selects both Channel 1 as well as Channel 2, pressing it will turn

on all three LEDs indicating that any command sent will hereupon apply to all channels. LEDs

will remain on until a command button is pressed, or until its timeout period has elapsed

with no command.

c. Pressing any of the command buttons will elicit a fast LED blink sequence on the selected

channel. When a combination of two command buttons is pressed simultaneously, a slow

LED blink sequence is activated on the selected channel. Note that the ALL channel mode

does not recognize simultaneous button combinations.

2. Functional instructions

a. To program a new channel, make sure the receiving device is disconnected from any power

source. Select the desired channel on the wireless transmitter by pressing one of the

channel buttons and connect power to the receiving device. Within 90 seconds of the

receiving device having powered on, simultaneously hold down the two direction buttons

on the wireless transmitter. The LED indicator on the selected channel will begin a slow blink sequence. Since the receiving device contains a motor in most cases, the motor will briefly jog forwards and back as confirmation that the channel has been successfully programmed. b. To reverse the running direction of the motor, the same procedure as above applies with the exception that the STOP and DIRECTION 1 buttons are pressed in this case.
