PRESET PROGRAMS
At delivery this processor is programmed with the following (variable) settings.
To return to these settings at any time.

INSTALLATION
How to connect the sensors
Connect the provided sensors as shown in the diagram.
For remote connections use a standard 0.5-square millimetre
Note
two-pole wire for
connections, by insulating and sealing the joins carefully. -O.C.- is
*1)
displayed when the temperature sensor wiring is open, -S.C.- is
*1)
displayed when the temperature sensor wiring is short circuit.

How to connect the line
*1)
Connect line on terminals L-N.
*2)
How to connect the contacts
*3) Connect terminals on the terminal block (contacts up to 4AMP.AC1)
to the loads as shown in the diagram.
*3)
As it company policy to continually improve the products the Manufacturers
