FUNCTION 

S

impleWorx products are 

designed to provide 
simple remote control 
for lighting and other 
electrical loads without 
running any new wiring. 
They connect or “link” to 
one another by 
communicating over the 
existing electrical power wires.   

One transmitter can be linked to as many receivers 
as necessary. Each receiver has the ability to link to 
eight transmitters. 
 
The SimpleWorx Digital Astronomical Timer (DAT-4) 
will control 4 different channels/groups with sixteen 
timer events and each can be set for: 

-

 

a specific time of day 

-

 

a specific day of the week (or every day) 

-

 

sunrise (with 15 minute offsets) 

-

 

sunset (with 15 minute offsets) 

Sunrise/sunset calculations are made each day for 
your location.  

-

 

Enter your latitude and longitude 
(itouchmap.com/latlong.html) in the setup 
procedure.
