Service bulletin SB2507
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
VDL Van Hool has received a few complains about the improper operation of the interior heating system. Investigation has shown that this is caused by an improper setting of the pressure regulator on the Burkert valve block. The too low setting of the pressure regulator prevents the water valves from opening when requested by the control system.
