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 con®gurable security level. If certain functions are not available (changing set points, chang- ing programming schedules), the thermostat security level may be con®gured to exclude those functions. Call the installer to recon®gure the security level.

·schedule period (Occupied 1, 2, or 3; or Unoccupied)

·setup indicator (programming mode)

·lock indicator

·start/stop indicator (schedule period program mode)

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- ing mode will adjust only the heating set points. The UP ARROW and DOWN ARROW buttons are also used in pro- gramming mode.

B. Override Button

The Override button is used to force the thermostat from Un- occupied mode into the Occupied 1 mode comfort settings. The Override period will be set at 30 minutes. The thermostat
