Product Description
The Siemens Venturi Air Valve is a pre-packaged,
easy to install airflow measurement and control
solution. It provides stable and precise airflow
control of room supply, room general exhaust or
fume hood exhaust.
These instructions explain how to field install or
replace the BACnet Laboratory Controller Module
LCM.
This BACnet LCM-OAVS VAV Room Pressurization
Controller with HW Reheat and Two Fast-acting
Venturi Air Valves — One Exhaust, One Supply
features VAV control of a laboratory room with one
supply duct, one exhaust duct, and up to six Fume
Hoods. It uses fast-acting electronic actuators
(shipped separately) to control the supply and
exhaust Venturi air valves.
This controller is built on a BACnet Programmable
TEC (PTEC) platform that supports up to two
Offboard AVS signals; however, Onboard AVS
transducers are not supported. Offboard Air
Module(s) (OAM) house AVS transducers and send
signals to the AVS input(s) on the LCM OAVS
board.
The LCM can operate stand-alone, with a field
panel, or as part of a network.
