Diagram for B10642 connections with 0-10 V DC thermostats/signals
B10642 connection with 0-10 V thermostats
Y2
Make the electrical connections to a thermostat that is
suitable for the purpose, according to the diagram in the
picture
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.
