CONTROL PANEL
The remote control panel should be installed on a guide DIN in a wall-mount electric board; the
space encumbered corresponds to 6 modules.
The control panel includes 3 terminal strips for:
-
connection of the unit with 4 threads to feed the panel (24VDC) and enable serial
communication with the electronic card;
-
the digital inputs of the various functions;
-
the two digital relay outlets that activate a circulation pump and a failure signal.
CONTROL PANEL CONNECTION
ModBus CONNECTION: this should be performed using a shielded 4-thread wire, section
0,5mm2; insert the terminal resistance in A and B. Thread V+ provides a 24V feed to the panel.
OUTLET RELAY
-
C01-NO1: 250V AC – 5A relay that activates when water circulation is required, useful
to control the pump.
-
C02-NO2: 250V AC – 5A relay that activates when a signal turns ON, useful to provide
an alarm signal from remote.
