Update facts:

• Software update for the new Bosch BOVB, M18, 3 and 5 ton (silver)
• Old software version is #32
• New version is #33
• Update time required: less than 1 minute.

Update version 33 changes:

• Improved modulation range
• Improved adaptive technology coil temp
• Improved Unico performance

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:



4. Power on the system. (The LED will display”-00” when it is updating the program, it will display “y–” once it has succeeded)
5. Disconnect Power. Remove USB drive.
6. Power unit back up ( you can go to check points #24, should read 33 new software version )
