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.

Fig. 1 — Thermostat Display

II. HEAT OR COOL INDICATOR

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.

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 Heating

mode will adjust only the heating set points. The UP

ARROW and DOWN ARROW buttons are also used in Pro-

gramming mode.

The set points are adjustable with the UP ARROW and DOWN

ARROW keys during Override mode.

NOTE: When the thermostat is in Unoccupied mode, the fan

will run only during heating or cooling operation, even if the

fan is set to FAN ON; this is the energy-saving smart fan

feature.

NOTE: If the thermostat is in Occupied mode and the Over-

ride button is pressed, the thermostat will go into Unoccu-

pied mode immediately. The thermostat will remain in Un-

occupied mode until the next Occupied start time.

The Mode button selects the operating mode of the thermo-

stat. If OFF is selected, the thermostat will not enter Heat-

ing or Cooling mode. If HEAT is selected, the thermostat will

only enter Heating mode (if the room temperature is below

the heating set point). If COOL is selected, the thermostat

will only enter Cooling mode (if the room temperature is above

the cooling set point). If AUTO is selected, the thermostat will

enter Heating or Cooling mode based on the room tempera-

ture and the heating and cooling set points. If PROGRAM

ON is selected, the stored schedule is enabled and the ther-

mostat will follow the Occupied and Unoccupied schedules

stored in its memory.

The UP ARROW and DOWN ARROW buttons are used to

scroll through programming set points. The buttons are also

used to answer yes or no.

Fig. 7.

12. After all the times and set points for each day have

been entered, press the Program button to ﬁnish en-

tering the schedule.

NOTE: The thermostat will continue to follow the schedule

until a new one is entered.

•

If only one occupied schedule is selected, the Occupied 2

and 3 schedules are skipped.

If the start time is set later in the day than the stop time,

the program will run from midnight of that day to the stop

time and then from the start time to midnight.

If NO was selected, the schedule will automatically

change to the next day and the user must enter the oc-

cupied and unoccupied schedules for that day.

•

If the same start and stop times are programmed for an

occupancy schedule, the thermostat will be in Occupied mode

for 24 hours.

NOTE: Occupied 1 schedule heating and cooling set points

are the same for each day. Occupied 2 and 3 set points may

be set to different values for each day of the week.

If one occupied period starts or stops within another occu-

pied period, the lower numbered schedule has priority. For

example, if schedule Occupied 3 is running for 24 hours

and occupied schedule 2 comes on from 1 to 3 PM, the set

points from Occupied 2 are in effect from 1 to 3 PM.

If YES was selected, the schedule will be copied to the

next day. The schedule copy may be repeated until Sun-

day is reached. The Sunday schedule cannot be copied

to Monday.

B. Overriding the Schedule

The schedule can be overridden during operation by pressing

the UP or DOWN ARROW buttons to change the desired tem-

perature. The thermostat will use the new set point until the

next scheduled time period starts.
