FAN OPERATION (High Speed Thermostat)
If the fans are set to run at low speed and the temperature in the hood exceeds 160°
Fahrenheit, the Fan speed thermostat will switch to the Normally Open Contact and switch
power from the low speed windings to the high speed windings. When the temperature
drops below 160°, the thermostat will switch back to the Normally Closed contact and the
fan speed will revert to low operation.
