GENERAL
Bryant’s 7-day, commercial, programmable thermostats are
wall-mounted, low-voltage thermostats which maintain room
temperature by controlling the operation of an HVAC (heat-
ing, ventilation, and air conditioning) system. Separate heat-
ing and cooling set points and auto-changeover capability
allow occupied and unoccupied programming schedules for
energy savings.
All thermostats allow up to 3 occupied and one unoccupied
time/temperature setting to be programmed per 24-hour
period. Each thermostat stores programs for 7 independent
days. Batteries are not required. During power interruption
the internal NEVERLOST™ memory stores programs for an
unlimited time.
IMPORTANT: The thermostat has a configurable security level.
If certain functions are not available (changing set points, chang-
ing programming schedules), the thermostat security level may
be configured to exclude those functions. Call the installer to
reconfigure the security level.
CONFIGURATION

The thermostat display is located in the center of the ther-
mostat. See Fig. 1. The following information can be dis-

II. HEAT OR COOL INDICATOR
A Heat or Cool indicator is located on the bottom left cover of
the thermostat. See Fig. 2. The light will be red if the ther-
mostat is in Heating mode. The light will be green if the ther-
mostat is in Cooling mode.
III. THERMOSTAT FRONT PANEL BUTTONS
The thermostat has buttons on the front cover which are used
to raise or lower the desired set point and override the cur-
rent program. See Fig. 2.
A. Set Point Buttons
The UP ARROW and DOWN ARROW buttons will raise
or lower the current desired temperature set point. If the ther-
mostat is in AUTO mode, pressing the UP ARROW or DOWN
ARROW buttons will adjust both the heating and cooling set
points. Pressing the UP ARROW or DOWN ARROW buttons
in Cooling mode will adjust only the cooling set points. Press-
ing the UP ARROW or DOWN ARROW buttons in Heat-

ARROW and DOWN ARROW buttons are also used in pro-
