DuctStat has a wide range of applications. A few of them are:
Suncourt Inline Fans-Use a DuctStat
to turn an Inline Fan on or off that is installed in the ductwork. This keeps
you from having to run potentially long wires back to a fan motor in your
furnace and reading its wiring diagram to correctly connect the wires.
DuctStat can be used to turn on a light bulb or heat lamp when the temperature
falls below your set point in a hot box or other contained space that you want
to keep above a certain minimum temperature.
Indoor gardeners use the DuctStat to turn on fans to help cool hot grow lights.
DuctStat can activate a wide variety of fans if temperature in a room or space
rises above a user-determined maximum.
How does the Suncourt DuctStat work?
The DuctStat contains a
thermistor, which is a very sensitive
When the thermistor detects a change in temperature from your set point the
DuctStat activates. The min/max switch
on its face controls the maximum differential between on and off. Max stands for
maximum differential of about 7 degrees F. Min stands for minimum differential
of about 3 degrees F. Simply plug-in your 110 volt device to the DuctStat’s
grounded outlet and begin the setting procedure described in the included
If you want the DuctStat to turn a device on when the
temperature rises above your set point
you put it on the heat setting. If you
want the DuctStat to turn a device on when the
temperature falls below your set point you will want to put it on its
cool setting. The DuctStat will deactivate when the
temperature returns to your predetermined set point. Please see the operating
instructions for more detail on setting the DuctStat.
