This zone sensor module is for use with
cooling/heating CV applications. It
provides the following features and
system control functions:
• System control switch (Heat/Auto/Off/
Cool): Allows you to select heating
mode, cooling mode, automatic
selection of heating or cooling as
required, or turn the system off.
• Fan control switch (Auto/On): Allows you
to select automatic fan operation while
actively heating or cooling or
continuous fan operation.
• Dual temperature setpoint levers allow
you to set different cooling (blue lever)
and heating setpoints (red lever).
• Thermometer to indicate temperature in
the zone.
This zone sensor is for use with cooling/
heating CV applications. It provides the
following features and system control
functions:
• System control switch to select heating
mode (HEAT), cooling mode (COOL),
AUTO for automatic selection of
heating or cooling as required, or OFF
to turn the system off.
• Fan control switch to select automatic
fan operation while actively heating or
cooling (AUTO), or continuous fan
operation (ON).
• Dual temperature setpoint levers for
setting cooling (blue lever) or heating
(red lever).
• Thermometer to indicate temperatuare
in the zone.
• 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.
Zone Sensor
Options
The programmable night setback sensor
is for use in CV 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.
