STARTUP USING THE SETTING AND
DIAGNOSTIC DEVICE ZTH EU (BELIMO)
Short description
The VAV setting device ZTH EU allows efficient testing of VAV
and CAV installations. Installations fitted with the Belimo VAV
controller can be simply adapted to the room and user require-
ments. The VAV setting device ZTH EU replaces the previous
setting device ZTH-GEN (2007-2014).
All standard Belimo VAV controllers with integrated PP commu-
nication (from 1992) that are sold in the EU can be set using the
ZTH EU.
