SUN-500 CURTAIN/SUN BLIND SWITCH 
8
Remarks 
 Reminders 
•  This product is a switch/receiver and is intended to control motors for sun blinds (rolling shutters, mini-
blinds etc.) by means of a suitable COCO transmitter. 
•  Only COCO transmitters on which a letter code (="house code") is set manually are suitable to control 
the SUN-500. COCO transmitters that contain a pre-programmed code (part number begins with "A") 
are not suitable for this product. 
•  The receiver only works with a 230 Volt power supply. The internal switch contact of the SUN-500 is not 
connected to the 230 Volt mains power. It is therefore possible to switch low-voltage motors (e.g. 12 of 
24 Volt). 
•  Approx. 2 minutes after operation of the SUN-500 with a COCO transmitter, the COM contact (see 
"Explanation" between [4-5]) always returns to the rest position (="off"). Due to this automatic switching, 
the SUN-500 can also be used as a timed switch. 
•  Operation of the transmitter: (1) Press the ON button: sun blind raises, (2) Press the ON button: sun 
blind stops, (3) Press the OFF button: sun blind lowers, (4) Press the OFF button: sun blind stops. 
•  If your sun blind lowers with the ON button and rises with the OFF button, this is not a problem. If 
desired, however, you can interchange the switch wires of the motor (on terminals ). 
•  To prevent interference, avoid placing multiple products close to each other. The minimum distance 
between units should be approx. 50 cm. 
•  If you use multiple SUN-500 receivers that you want to control simultaneously, the connected motors 
must have the same rotation direction for the raise and lower commands. 
•  If the product does not work or does not work properly: 
-  Check the batteries in the transmitter. 
-  Make sure the letter and number combination of the SUN-500 matches that of the transmitter. 
-  Switch the mains power off for 10 seconds to reset the SUN-500. 
-  Make sure there is no other receiver in the immediate vicinity. 
-  Check whether there is too much wiring present near the SUN-500 or whether other metal objects 
may be causing interference.
