OPERATION CONTINUED
Figure 3 is an example application where the system is
completely set up.
Please note:
• The controller is plugged into an approved GFCI
circuit protector, which is plugged into an approved
extension cord (not shown).
• The temperature sensor is placed between the
heated wrap and the outside of the IBC.
• The heated wrap is plugged into the output
receptacle of the controller.
• The controller is hanging from the top strap of the
heated wrap.
• Removeable vinyl top is placed over the top of the
IBC.
• The system is positioned on a solid, wood-topped
pallet to reduce heat loss out of the bottom of the IBC.
The controller is programmed at the factory to be in its
heating mode and to turn the heater OFF at the OFF set
temperature and turn it back ON when the temperature
of the probe/sensor reaches the ON set temperature.
Unless in the programming mode, the display shows the
current temperature of the probe. It is important to note
that the temperature of the contents in the vessel will
lag this displayed temperature. This amount may vary
depending on application. As the contents in the vessel
approach the desired temperature this difference will
be much less.
The green light will glow when there is power to the
output receptacle and go off when the power is not
connected to the receptacle. There should be an
audible click as the controller turns the power to the
output receptacle on or off.
To program the thermostatic controller to the new OFF
and ON temperatures, press MENU. The controller is
now in programming mode. With OFF flashing, push
MENU again. The controller will flash the current OFF
temperature. Use the UP and DOWN arrow buttons to
increase or decrease the temperature set point, one
degree per push. When the correct OFF temperature is
flashing on the display, press MENU again. This scrolls
the controller to the ON variable. Press MENU again
to access the ON variable. Use the UP or DOWN arrow
buttons to increase or decrease the temperature set
point, one degree per button push. Press MENU again
to exit the ON variable. Press the UP or DOWN arrows
simultaneously again to exit the programming mode.
The display will revert to a steady display of the present
temperature of the probe/sensor.
CAUTION! Do not program the controller to
OFF > 170°F, as this may damage the heating
blanket, vessel and/or product.
