9.4 Bi-thermostat for adjusting fan start-up
During normal operation the sensor of the bi-thermostat rotates and, once the temperature set on the
set point has been reached, closes the contact that supplies power to the fan.
The bi-thermostat has a bi-metal thermostat that operates the fan within 90 seconds of being enabled.
IMPORTANT !!
When setting temperatures and using the adjustment levers, hold the housing firmly so that
it does not rotate and supply power to the sensor.
