Identifying radiant heat zones

I have a 4 bedroom Eichler and part of the house is just not heating up. I know that there are valves in hallway closet that control the water flow, but am unsure how to translate the labels into actual locations in the house. The labels on the 10 valves read:

LE
LO
LC
B/C
BIB
LA LB
B2A B2B
B4A B4B
B3
B/A

Has anyone been through this before? Any way to fix things rather than just randomly turning up a valve and seeing what happens?

Thank you.

I would call a HVAC specialist that knows about Eichler homes and radiant heating. Just guessing I would say the labels with 'B' are bedrooms. I'm thinking the biggest or master bedroom would be 'BA', 'BB' and 'BC'. Bedroom 3 must be the smallest because it has just one valve. As far as the other valves, it look like they are labeled A-E with 'L' being the first letter. There's not telling which room is A and which room is E or D. That's why I think a HVAC specialist could turn them on and record the floor temperatures to figure out which valves control which areas of the home. Then the HVAC guy can label them for you to understand.
