6.2.4 Flow In Adjustment.

The Flow Input Adjustment is not currently
implemented in the C-More Control Panel. When
implemented, it will allow the water flow rate
measured by a flow sensor to be adjusted ± 5%.

6.2.5 CO In Adjustment.

The Carbon Monoxide (CO) Input Adjustment is
not currently implemented in the C-More Control
Panel. When implemented, it will allow input flow
rate to be adjusted ±5%.

6.2.6 O2 In Adjustment

The Oxygen (O2) Input Adjustment is not
currently implemented in the C-More Control
Panel. When implemented, it will allow the input
oxygen level to be adjusted ±5%.

6.2.7 mA Out Adjustment

The Milliamp (mA) Output Adjustment permits
the output current to be adjusted from -1.0 mA to
+1.0 mA in 0.1 mA increments. The default
setting is 0.0 mA. This function is associated
with the mA OUT terminals in the I/O Box.
These terminals provide an output that can be
used to monitor setpoint, outlet temperature or
fire rate. The function to be monitored is
selected in the Configuration Menu. To view or
adjust this setting, proceed as follows:

1. Press the ▲ or ▼ arrow key until mA Out Adj

is displayed along with the current
adjustment setting in mA.

2. If the desired setting is not displayed, press

the CHANGE key. mA Out Adj will begin to
flash.

3. Press the ▲ or ▼ arrow key to increment or

decrement the display until the desire value
appears.

4. Press ENTER to store the displayed setting.

5. Press BACK to exit the mA Out Adj function.

6.2.8 A/F Sensitivity

The Air/Fuel (A/F) Valve Sensitivity is used to
set the allowable error on the Air/Fuel Valve
Stepper Motor position. The sensitivity is
adjustable from 1% to 5% in 1% increments.
The default value for this setting is 2%. The
sensitivity setting represents the maximum
percentage that the output fire rate can change
without the valve having to move. For example;
if the sensitivity is set for 2% and the output fire
rate changes 1%, no movement is required. To
view or change the A/F Sensitivity, proceed as
follows:

1. Press the ▲ or ▼ arrow key until A/F

Sensitivity

is displayed. The currently set

sensitivity percentage will also appear in the
display.

2. If the desired percentage is not displayed,

press the CHANGE key. A/F Sensitivity will
begin to flash.

3. Press the ▲ or ▼ arrow key to increment or

decrement the displayed sensitivity
percentage to the desired value.

4. Press ENTER to store the new setting.

5. Press BACK to exit the A/F Sensitivity

Calibration.

6.2.9 Power Reset

The Power Reset function can be set to
Automatic or Manual. However, AERCO strongly
recommends that this function always be set to
the Automatic (Default) setting.

6.2.10 Water Temp Reset

The Water Temperature Reset function can be
set to Automatic or Manual to indicate whether
the unit can be restarted or must wait for manual
acknowledgement following a high water
temperature fault and fault correction.
Regardless which setting is used, the High
Temperature fault message will be latched. The
default for this function is Automatic. To view or
change the setting, proceed as follows:

1. Press the ▲ or ▼ arrow key until Water

Temp Reset

is displayed. Automatic or

Manual

will be displayed to indicate the

present setting.

2. If the desired setting is not displayed, press

the CHANGE key. Water Temp Reset will
begin to flash.

3. Press ENTER to toggle the display.
