Bosch Heat Pump USB Upgrade Instructions:

Before this is used we want to make sure that the cycles of the thermostat being used are set to 1 cycle per hour to assure the unit is getting that uninterrupted run time. Check Code #22 to see what the unit has run uninterrupted. If it is a UNICO system, make sure the unit has been charged per Unico’s Superheat/Subcool guidelines.

Steps:

  1. Use the USB “Magic Stick” provided by Able OR download the software patch file and copy to an empty USB drive
  2. Disconnect all power to unit ( pull disconnect, no call for cooling ).
  3. Insert flash drive into USB port on board:
