Zone Sensor
Options
This wall-mounted zone sensor ships with
every Signature Series unit, CV or VAV.
Additional sensors are also available for
order using the accessory model number.
It includes an internal thermistor and
should be mounted in the zone. This
sensor is available for use with all zone
sensor options to provide remote sensing
capabilities.
This wall-mounted zone sensor option is
for use in VAV applications. Features and
system control functions are:
• Temperature sensing in the zone
• System control switch with mode
setting for Auto or Off
• Supply air single temperature setpoint
• Function status indicator lights:
SYS ON glows continuously during
normal operation, or blinks if system is
in test mode.
COOL glows continuously during
cooling cycles or blinks to indicate a
cooling system failure.
HEAT glows continuously during
heating cycles or blinks to indicate a
heating system failure.
SERVICE blinks or glows to indicate a
problem. These signals vary depending
on the particular equipment used.
Programmable night-setback sensor,
Accessory Model Number Digit 6 = J,
BAYSENS020
This programmable night setback sensor
is for use in VAV applications. The sensor
has a time clock function that provides
communication to the self-contained unit
through a 2-wire communications link.
The desired transition times are
programmed at the night setback sensor
and communicated to the self-contained
unit.
The programmable night setback
(unoccupied mode) operates through the
time clock provided in the sensors with
night setback. When the time clock
switches to night setback operation, the
outdoor air dampers close and heating/
cooling enables or disables, depending on
set-up parameters. As the building load
changes, the night setback sensor
energizes the self-contained unit’s
heating/cooling (if enabled) function and
the evaporator fan. The self-contained
unit will cycle through the evening as
heating/cooling (if enabled) is required in
the space. When the time clock switches
from night setback to occupied mode, all
heating/cooling functions begin normal
operation.
When using the night setback options
with VAV heating/cooling, maintain
airflow through the self-contained unit by
electrically tying the VAV boxes to the
unoccupied output relay contacts on the
unit’s RTM module board or by using
changeover thermostats. Either of these
methods will assure adequate airflow
through the unit and satisfactory
temperature control of the building.
