Thermal protection input for pump P1 motor.
Electrical characteristics: 230V ac not insulated.
ATTENTION! For pumps with thermal protection KK, remove the KK terminals
jumper of the panel and connect them to the protection cables present in the
pump cable.
Thermal protection input for pump P2 motor.
Electrical characteristics: 230V ac not insulated.
ATTENTION! For pumps with thermal protection KK, remove the KK terminals jumper of
the panel and connect them to the protection cables present in the pump cable.
Terminals for connecting digital and analog inputs
The terminals for connecting the electric panel input may be connected according
to the type and actual needs of the system.
ATTENTION! Digital inputs have priorioty!
Pressurisation function: If the maximum pressure switch (P.Max) is connected, remove the
by-pass jumper supplied as a standard feature between the respective terminals!
Draining function: the by-pass jumper IS NOT FITTED!
