Installation and Configuration Guide, Rev. G

that one day in the Individual Days menu 

may be easier (two entries) than entering 

schedules for each day separately in the 

Individual Days menu (five entries).

NOTE:

  The last overlapping entry overrides 

any other. For example, suppose the 

WEEKDAYS menu is used to set all 

weekdays for 7:00 AM ON and 5:00 PM 

OFF, and then the INDIVIDUAL DAYS 

menu is used to add some additional 

evening meeting ON times for Tuesday 

and Wednesday. If the WEEKDAYS menu 

is later used to change the ON time from 

7:00 to 7:15, schedules for all the individual 

week days will be reset to conform to 

what appears in the WEEKDAYS menu 

and any special times for individual days 

will be erased. (Special day schedules will 

then need to be added again through the 

INDIVIDUAL DAYS menu).

The Holiday entries will override the normal oc-

cupied weekly schedule entries and keep those days’ 

settings at their setback values. (Setback values are 

entered in the Setpoints section of the Main Menu.)

Trends

The BAC-120063CW-ZEC Flexstat is preconfigured 

for the following trend logs: 
1. 

DAT

 (AI2 sampled at 

30 second

 intervals).

2.  DAT (at 

1 minute

 intervals).

3.  DAT (at 

5 minute

 intervals).

4. 

Number of zones

 (AV22 at 1 minute intervals) of 

SimplyVAVs.

5.  Number of 

calls for cooling

 (AV24 at 1 minute 

intervals) from SimplyVAVs.

6.  Number of 

calls for heating

 (AV25 at 1 minute 

intervals) from SimplyVAVs.

7. 

Duct static pressure

 (AV103 at 1 minute intervals) 

from an optional CSP-4702.

8. 

Duct static pressure setpoint

 (AV104 at 1 minute 

 SETPOINTS

COOL DAT SETPOINT:

HEAT DAT SETPOINT: 130° F
DUCT ST STPT: 0.5 in H2O

55° F

The optional duct static pressure setpoint is also in 

this menu.

NOTE:

  The airflow minimum limit in each 

SimplyVAV

 controller needs to be at least 

10 cfm (and 25 cfm is recommended). 

Otherwise, the controller will not properly 

sense the local duct DAT during minimum 

flow. 

See 

BAC-8000 series

 for more 

information about the controller-actuators.

Heat/Cool, Fan, Occupancy, and Override

When the fan is commanded to run, the animated 

“FAN” icon on the display rotates.

 When the fan 

command stops, the fan icon is motionless.
The “OCC” icon shows a sun when in Occupied 

mode and a quarter moon when in Unoccupied 

mode.
HEAT or COOL will show (and be animated when 

there is an active command to move the temperature 

toward the setpoint via mechanical heating/cooling 

or an economizer), depending on the current mode. 

This can also be turned OFF.

To override these modes

 from the Home (tempera-

ture display) screen, press the 

Left

 arrow button. 

Press 

Up

 or 

Down

 to get to the desired line and then 

Enter

 (twice) to edit the mode setting. Press 

Left

 

to 

exit to Home.
