Enabling Autozero Module

Enabling Autozero Module
If an Autozero Module is used, enable it by setting CAL MODULE to YES.
NOTE:
For a controller without an Autozero Module, the damper is commanded closed to get
a zero airflow reading during calibration. For a controller with an Autozero Module, the
damper is closed only for the first calibration after controller initialization or power up.
Selecting Automatic Calibration Option
1. Using the following table, set CAL SETUP to the value that best meets your job
requirements.
2. If appropriate, change CAL TIMER from the default of 12 hours. This setting
applies only if your choice for CAL SETUP includes Option 4.
NOTE:
The air velocity sensor should be calibrated at least once every 24 hours. Make sure
that the sensor has been calibrated before balancing takes place, as this will affect
the balancer’s results.
CAL SETUP Options.
CAL SETUP
(value)
Description
0 Calibration occurs ONLY when the point CAL AIR is set to
YES
.
1 Calibration occurs when the field panel commands a Day/Night mode
changeover. Actual calibration is subject to a time delay of 0, 1, 2, or 3
minutes. This delay is determined by the point CTLR ADDRESS divided
by 4. The remainder is the time delay in minutes.
Example:
If CTLR ADDRESS = 11, then the controller will wait 3 minutes
(11 ÷ 4 = 2 R3) after it receives the Day/Night mode changeover
command before beginning the calibration routine.
2 Calibration occurs immediately after the override switch is pressed.
4
(factory default
value)
Calibration occurs on the time interval set in the point CAL TIMER.
Example:
If CAL TIMER = 12, then the calibration period is 12 hours.
Actual calibration is subject to a time delay based on the value of CTLR
ADDRESS. See the example in Option 1 in this table.
NOTE:
Since these are additive values, options can be combined by summing their numbers.
For example, to calibrate in Options 1 and 2, set CAL SETUP to
3
