Amana CVC96 BB Series Installation Instructions Manual page 36

The furnace includes three on-board push buttons allowing
users to navigate indoor and outdoor system menus. The
Right and Left buttons allow the user to scroll through the
main menus and to then scroll through available options
within specific menus. The Center button is used to enter
into a main menu and to then permanently select options
within those menus.
NOTE: After scrolling to the desired option
within a menu, that option may be flashing on the
7-segment displays. This indicates the option has
not been officially selected. Pressing the Center
button two times will select that option. The first
press will stop the flashing. The second will make
the selection official and return you to the main
menu.
Accessories
Accessory Control (Ventilators)
If an external humidifier, dehumidifier or ventilator is
installed, it may require airflow from the HVAC system to
function accordingly.
1. Make sure the installed 24VAC thermostat is capable
of controlling the accessory or accessories.
2. Connect the appropriate accessory control wires
to the accessory devices from the thermostat
(see thermostat manual for connection and setup
instructions).
3. If the thermostat is capable of providing a continuous
fan call (G signal) during accessory operation:
Make sure to connect the thermostat G terminal to
the G terminal on the indoor unit. Setup thermostat
to ensure G signal is energized during accessory
operation.
4. Select the appropriate fan only airflow for the
accessory using the indoor unit push button menus or
the CoolCloud HVAC phone application.
5. Using the thermostat, independently test each

accessory in addition to independently testing
continuous fan mode.
Optional Low Voltage Humidifier Connection
Furnaces produced mid 2019 and later will have a 4" brown
wire on the low fire pressure switch for 24 volt humidifier
connection. To connect a 24 volt humidifier:
• Turn off power to the furnace
• Strip insulation from the end of the 4" brown wire.
• Refer to connection diagram below and follow
humidifier manufacturer instructions.
Ramping Profiles
The variable-speed circulator offers four different ramping
profiles. These profiles may be used to enhance cooling
performance and increaqse comfort level. Select ramping
profiles on the user menu.
• Profile A (1) provides only an OFF delay of one (1)
minute at 100% of the cooling demand airflow.
100% CFM
OFF
• Profile B (2) ramps up to full cooling demand airflow
by first stepping up to 50% of the full demand for
30 seconds. The motor then ramps to 100% of the
required airflow. A one (1) minute OFF delay at 100%
of the cooling airflow is provided.
50% CFM
OFF
1/2 min
• Profile C (3) ramps up to 85% of the full cooling
demand airflow and operates there for approximately
7 1/2 minutes. The motor then steps up to the full
demand airflow. Profile C also has a one (1) minute
100% OFF delay.
