Features
• LCM can be factory mounted on terminal units or
venturi air valves, or field mounted in panels
located for easier access.
• OAM factory mounted on terminal units or venturi
air valves eliminates field installation of airflow
signal tubing.
• Control applications available for a variety of
airflow control devices, including dampers,
terminal units, fans with VFDs and venturi air
valves.
• Control applications using a variety of actuation
types including high-speed electronic, low-speed
electronic and pneumatic (with transducers).
• Control applications that do not use a general
exhaust, do not require a second OAM.
• Airflow sensor is read five times per second,
independent of the output device loop time, giving
the most accurate reading at all times.
• Airflow sensor is automatically recalibrated
periodically to maintain highest accuracy.
• BTU Compensation temperature control
application allows tighter control without over-
cooling or over-heating during transients (requires
discharge temperature sensor).
• Supports the use of wall switch input to change
from occupied to unoccupied state.
• Optional room pressurization alarm output to
notify laboratory occupants.
• Reports airflow directly in actual cfm (lps).
• Electrically Erasable Programmable Read Only
Memory (EEPROM) used for storing control
parameters—no battery backup or re-entry of
data required.
• Quick return from power failure without operator
intervention that maintains room pressure
relationship.
• Maintains room pressurization during transient
conditions.
• Secure Mode prevents unauthorized users from
making changes to the TEC through the MMI port
or room sensor, supporting FDA 21 CFR Part 11
compliance guidelines for protection of electronic
records (see Application Information).
• User-adjustable offset for the calibration of room
temperature reading when required for validation
purposes (see Application Information).
