Operation
Fan speed is controlled according to the selected
profile, as shown in the chart opposite.
The fan will run at approximately 15% of maximum
speed below the minimum temperature and increase
to 100% at the maximum temperature.
If preferred, DIP switch 4 can be used to switch the
fan off below the set point.
CAUTION: During normal operation some controller components become very hot.

Description
Traditional fan speed controllers use voltage-chopping which can lead
to reduced life expectancy, damage to motor electronics and reduced
performance. The DC Temperature Controller regulates the electrical
power supplied to the fan to maintain optimum performance and reliability.
• For temperature sensitive speed control of 12V, 24V
• Fan speed increases with temperature between 20°C and 40°C or
• Alarm output through Open Drain connection or optional relay.
• Supplied complete with 2 metre long NTC thermistor.
*Note: Due to variations in motor electronics, a small number of mainly
high speed fans may not work correctly with this controller. A list of fans
which have been tested for compatibility is attached to this document.
