How to connect the line
Connect 230V line on terminals L-N.
Protect supply with adequate fuse.
How to connect the contacts
Connect terminals on the terminal block
(contacts up to 4AMP.AC1) to the loads as shown in the diagram.
How to connect the sensors
Connect the provided sensor as shown in the diagram.
For remote connections use a standard 0.5-square millimetre
two-pole wire for each sensor, taking great care over the
connections, by insulating and sealing the joins carefully. -O.C.- is
displayed when the temperature sensor wiring is open, -S.C.- is
displayed when the temperature sensor wiring is short circuit (exiting
condition of relays in this case is that setted in Cost, rY.OC - rY-SC).
