Zone Controllers

TAC Xenta 102-AX

VAV Controller

with Onboard Actuator and Air Flow Transducer

TAC Xenta 102-AX is a Lo n Ma r k

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

o n Wo r k s

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

measurement input.
