Zone Controllers

Lo n Ma r k

certiﬁed individual room controller for VAV applications (Variable

Air Volume ﬂow) connected to an external air ﬂow sensor (TAC GV). The

controller is intended primarily for VAV 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 sen-

sor, the air quality can be controlled in the zone. The controller can be oper-

ated stand-alone or within a L

o n Wo r k s

network. PI control with individual

P-band and I-time setting for heating and cooling. Can be monitored and

parameters can be set centrally via the central system or remotely with the

TAC Xenta Operator Panel.

FUNCTIONAL FEATURES

• Various applications:

Single-step control via external

air flow sensor and heating in

sequence. Heating operation by

modulating hot water radiator

valve.

• Slave function mode of

operation and setpoint for

several slave controllers are

controlled by one master.

• Setpointadjustmentviaawall

variable.

• Seven modes of operation:

comfort, standby, bypass,

unoccupied, off, slave and

purge mode.

• Airqualitybasedadjustments.

• Configurable limit values MIN

and MAX air flow limit.

• Alarm monitoring high or

low room temperature, open

window, temperature sensor

error, etc.

• Occupancy sensor, window

contact and cool-down

protection, CO
