Press ADVANCE TIME/DAY button until desired start time
is displayed.

6. Adjust setpoints.

Adjust setpoints using up and down buttons until desired
temperatures for the selected time period appear in display.
These setpoints will be used during the time period currently
displayed in clock window.

7. Complete time period programming.

Repeat 4 through 6 to program remaining weekly period start
times. Each weekly period can be programmed with 4 differ-
ent time periods.

8. Complete weekly schedule.

After completing start time programming, press SELECT
MIN/HR/DAY until MTWTHF reappears in clock display.

Repeat steps 3 through 7 to program weekly periods. Once
finished, this will complete programming of 1 zone.

9. Program a different zone.

To program a different zone, turn rotary switch to desired zone
to be programmed and repeat 2 through 8.

10. Exit program mode.

Exit program mode by pressing SET TIME/TEMP SCHED-
ULES button.

Overriding Programming

To override time programming, press any setpoint button. This
will also adjust setpoints for override period. Once setpoints are
adjusted, they will not change until the next programmed time
period for that zone.

If HOLD TEMPERATURES button is pressed, then current
setpoints will not change with time, but remain at last values
entered for as long as hold mode is active.

To release hold mode, press HOLD TEMPERATURE button a
second time.

The controller display will show the word HOLD whenever hold
mode is active.

Temperature Sensor Calibration

NOTE:

Temperature sensors are factory calibrated; however,

field calibration is recommended.

The setpoint display shows actual temperature (Fahrenheit or
Celsius).

The upper left-hand corner of display indicates the whole number
value. The lower right-hand corner indicated the tenths.

Pressing either HEAT or COOL button raises or lowers displayed
temperature by 1/10 of a degree.

If temperature readings are not stable within 0.5°F, refer to
troubleshooting section for details.

Damper Service Mode

The Damper Service Mode can be selected to check full operation
of each zone damper independently. The controller display shows
zone number in the upper left digits, and damper position in the
lower right digits. The left hand setpoint buttons will toggle the
zone number (1-4) and 5.

NOTE:

No. 5 not used for damper service mode, see below for

details when setting motorized bypass damper pressure relief limit.

When this mode is selected, all 4 zone dampers are activated and
opened to position 15. (See Table 2.) Fan will energize. Use right
hand setpoint buttons to toggle down from position 15 to position
0. This feature can verify that each zone damper is operating
properly by manually opening and closing each zone. When rotary
switch dial is moved onto another position, Damper Service Mode
will be cleared and controller will resume normal operation.

Bypass Damper Pressure Relief Limit

We do not encourage using a motorized bypass damper. Using a
barometric bypass damper is the preferred method to control
operating pressures in supply duct.

The display shows zone number in the upper left digits, and the
lower right digits show damper position. The left hand setpoint
buttons will toggle the zone number (1-4) and also to 5 where
collective damper position is programmed in for bypass. When it
is toggled to position 5 and annunciator is toggled from OFF to ON
with right hand buttons, controller totals all damper positions and
stores them. While displaying 1-4, the damper for that zone can be
directed to any position with right hand buttons. The collective
damper position that is programmed at position 5 is the minimum
total damper open position. The largest minimum open position is
60 (4 zones with 15 positions each). The number that is pro-
grammed in will be the minimum total damper open positions that
bypass will try to maintain. The bypass damper positions are 1 for
every 3 that the total needs. (Example: The maximum total is 60,
but only 3 dampers are open. This is only 45, so bypass takes 60,
subtracts 45, comes up with 15, and divides this number by 3. The
result is 5, so bypass goes to position 5.)

Step 15—Accessories

Refer to individual Installation Instructions packaged with kits or
accessories when installing.

HOME ACCESS MODULE

The Home Access Module (HAM) is designed to detect Comfort
Zone System errors. The HAM can report when system is
operating correctly, or when an error is detected. The HAM can
automatically call an ACS dealer or the ACS National Response
Center.

NOTE:

The HAM must be programmed via Report Logger or PC

Command Center Software prior to installation.

SMART SENSOR AND SMART SENSOR POWER PACK

NOTE:

These 2 accessories must be used together.

The Smart Sensor provides the ability to view and adjust setpoints
in zone where sensor is located.

The Smart Sensor replaces a Remote Room Sensor and requires a
single 5-wire conductor instead of a 2-wire conductor.

OUTSIDE AIR DAMPER

The outside air damper allows fresh outside air into building.
