EG 172

Working principle :

The EG 172 is a time switch for the 
automatic control of electrical loads.
It is fully programmable with a maximum
of 20 program steps. Each program step
can be applied to one or several days,
maximising the use of each memory
location.
The front cover is sealable preventing 
unauthorised access after completion of 
programming.

Warning :

at the beginning of use, please  

reset the device in order to clear the
memory before programming. 
This is achieved by using a pen to push
the reset button.
