POWERBLANKET® THERMOSTATIC CONTROLLER INSTRUCTIONS Thank you for purchasing a Powerblanket® GHT2002J Thermostatic Controller. Please read and understand these instructions before continuing.

VERY IMPORTANT: Place the temperature sensor between the heating blanket and that which is to be heated, for example, your barrel or tote. CAUTION Improper probe placement can result in unsatisfactory performance and/or damage to your vessel, product or heating blanket. CAUTION Do not submerge the temperature sensor - it is not waterproof.
Here is an example application where the system is completely setup. Please note: i) The controller is plugged into an approved GFCI circuit protector which is plugged into an approved extension cord (not shown). ii) The temperature sensor is placed between the heated wrap and the outside of the poly barrel. iii) The heated wrap is plugged into the output receptacle of the controller. iv) The controller is hanging from the top strap of the heated wrap.
exit the ON variable. Press the UP and DOWN arrows simultaneously again to exit 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 (77°C) as this may damage the heating blanket, your vessel and/or your product.
