Regulation according to the running hours
The algorithm switch on and off the loads according to the running hours of each load. In this
way the running hours are balanced.

This draw highlights the doF time: the loads are in fact turned off only when the doF time is
over.
7. Mounting & installation
The instruments are suitable only for internal use. They are panel mounted, hole dims 135x69
mm, and fixed with the supplied clips.
The ambient operating temperature range is between 0÷55°C.
