The motor switches to high speed as the air temperature exceeds 2 °C above the set
thermostat set point. The motor revers to the pre-set lower speed as the air temperature
drops below the thermostat set point. This pattern is used to keep air temperature to
within 2 °C. In this case the motor speed switches are rare.
Operation of the electronic temperature and speed control module.
Set the desired air temperature (thermostat set point) by turning the thermostat control knob
10 and the minimum rotation speed (air flow rate) by turning the speed control knob 9.
The fan operation indicator 11 lights up as the fan is started.
If the air temperature increases above the thermostat set point the fan switches to the
high speed (maximum air flow rate). Synchronously, the thermostat indicator 12 lights up.
If the temperature decreases below the thermostat set point the fan switches to the pre-set
lower speed. As the air temperature exceeds the set thermostat set point, the motor switches
to higher speed and the switch delay timer is activated for 5 min.
The motor reverts to lower speed as the air temperature drops down below the thermostat
set point and only after 5 minutes countdown. This pattern is used for exact air
temperature control.
