ARO - automatic motor speed controller

Kod produktu: kod produktu


Motor speed controller ARO measures temperature in the fireplace hood with a special thermal probe (the temperature is shown on a LCD display) and sets the speed of the hot air ventilator.
ARO measures the temperature in the fireplace hood and sets the hot air ventilator motor speed in two modes: Manual (MAN) and Automatic (AUTO).
In manual mode (MAN) the speed can be set in scale of 0 .. 10, where 0 means turning the motor off and 10 means maximal rotating speed value. Temperature measured by the probe has no influence on the motor rotating speed.
In automatic mode (AUTO) speed of the motor is being automatically adjusted to the temperature measured by the probe. Above 40oC the ventilator is being turned on at the minimal speed. The speed increases proportionally to the rise of temperature, achieving its maximal value at 80oC.
After switching the ARO off (with the ON/OFF button, or in case of lack of electricity supply) the actual mode and speed set is remembered and restored after switching the device on again.
