Diagram for B10642 connections with 0-10 V DC thermostats/signals

Make the electrical connections to a thermostat that is
suitable for the purpose, according to the diagram in the
picture
L-N 230V-50 Hz electric power supply
10V device pilot input 0÷10 V
hot water solenoid valve (230V/50Hz 1A powered
Y1
output)
output for servomotor mobile aspiration panel (230
Y2
V/50Hz 1A powered output)

B10642 connection with 0-10 V thermostats

If the S1 input to which is connected the grill safety
microswitch is closed, the 10 V input activates solenoid
valve Y1 and adjusts the number of rotations of the fan.
The speed "ramp" provides a linear adjustment from
the minimum value (400rpm) to the maximum value
(1400rpm) for voltage values ≥ 1.1V÷10 V DC.
The motor is off with values below 1 V DC.
The Y1 valve is enabled by voltage > 1 V DC and turns
off when the same falls below 0.9 V DC.
