Bosch FHP Age

Can somebody help me determine the age for the self contained heat pump with no outside condenser manufactured by Bosch FHP? The serial number format does not match the reference chart I have.
Model - BP048-1VTN
Serial # 3540-112-TW0001-T111M40851

Oops sorry wrong one.
No time to look up the one for heat pumps but someone will get it soon.

Kevin - any luck with this one?

Sorry Greg I have not been on my main computer at the office since my last comment to you. I am suprised no one could help you.

I got it 2012, thanks!

How did you come up with this determination?

Not sure about Bosch specifically but with Florida Heat Pump (FHP), the first letter is the year and the second letter is the month.
