Zone Controllers
TAC Xenta 102-AX
VAV Controller
with Onboard Actuator and Air Flow Transducer
TAC Xenta 102-AX is a L
ON
M
ARK
®
compliant individual room controller
intended for VAV heating and cooling applications with one or two stages
of reheating. The controller keeps a constant temperature in the zone by
controlling the air flow and heating stages. By using a carbon dioxide sensor,
the air quality can be controlled in the zone. TAC Xenta 102-AX is equipped
with an integrated, static air velocity transducer and a motorized bidirectional
actuator in a single package. The differential pressure air velocity transducer
requires a minimum of maintenance. Thus it is also well suited to be placed
in the zone return air duct.
FUNCTIONAL FEATURES
•
Various applications:
Single-step VAV controller via
internal air flow sensor and
heating in sequence up to 3
stages.
•
Setpoint adjustment via STR
200, 202 or 250 wall modules
or via a L
ON
W
ORKS
®
network
variable.
•
Seven modes of operation:
occupied, standby, bypass,
unoccupied, morning
warm up, purge mode and
emergency pressurization/
depressurization.
•
Air quality based adjustments.
•
Fan control can be enabled/
disabled either in parallel or
serial mode.
•
Alarm monitoring high or
low room temperature, open
window, temperature sensor
error, etc.
•
Occupancy sensor, CO
2
measurement input.
