c) Delete all transmitter codes from memory
For deleting all codes stored in the memory of the receiver the programming key is held down
until all four LEDs are lit together (after 6- 7 seconds). The key is released and pressed again
to conrm the deletion of the complete memory.
The completion of the memory formatting is conrmed with alternate blinking of both LEDs
The setting of the toggle/timer mode for both channels is not affected by this procedure.
d) Functions in normal operation mode
After learning codes from transmitters, all channels of the receiver can be controlled
independent of each other according to the congured operation modes.
The yellow LED for channels 1-4 indicate the current status of the associated relay.
If the LED is lit, the terminals ‘NO’ and ‘C’ of this channel are connected electrically.
If the LED is dark, the terminals ‘NC’ and ‘C’ of this channel are connected electrically
PLEASE DO NOT EXCEED THE MAXIMUM VOLTAGE OR CURRENT RATING
FOR THE RELAY CONTACTS
Maximum range to be obtained:
The functional range is up to 50 meters under best conditions but could be limited by objects
blocking the line of sight between transmitter and receiver. Other RF-noise on the same
frequency (e.g. from babyphone, wireless thermometer, or other 433 MHz devices) could also
limit the effective range of the remote set.
Changing the battery of the handheld transmitter
To replace the remote control battery (Type 27A, 12V, Alkaline), loosen the two screws on the
back of the transmitter housing and remove the back cover of the housing.
Observe polarity: The ‘+’ terminal of the battery must face the at contact plate.
Used batteries must not be disposed of with the household waste, but must be returned to a
designated collection point.
External Antenna Connector
The 3-pin header on the right side of the terminal block for power supply is for the connection of
an optional external receiver unit. If not using the external receiver, please leave this connector
open.
Mounting instructions
The 4-ch remote receiver could be mounted on almost any even surface, mounting on metal
may have a negative effect on functional range. Using the included mounting clips, the case
can be snapped onto DIN mounting rails with 30 mm width.
