SEQUENCE OF OPERATION FOR *AM8
2. The EVC will receive input from the two tempera-
ture sensors and start to control 1st stage super-
heat.
3. When a request for 2nd stage cooling is received,
the AFC sends a command to the serial com-
municating blower motor to run at 100 % cooling
airflow.
4. The EVC will now control superheat for 2nd stage.
5. When a request for cooling is removed, the AFC will
turn off the blower motor after any user selected
fan-off delays have expired.
NOTE: Delay profiles from the thermostat may change
blower motor timing and actual airflow demand
Heatpump (compressor only)
1. When a request for 1st stage heat is received, the
AFC sends a command to the serial communi-
cating blower motor to run at 1st stage heating
airflow.
2. Humidifier contacts close
3. The EVC will drive the EEV to the heating position
and refrigerant will flow in the reverse cycle.
4. When a request for 2nd stage mechanical heat is
received, the AFC sends a command to the serial
communicating blower motor to run at 100 % heat-
ing airflow.
5. When a request for heatpump is removed, the hu-
midifier contacts open and the AFC will turn off the
blower motor after any user selected fan-off delays
have expired.
NOTE: Delay profiles from the thermostat may change
blower motor timing and actual airflow demand
Electric Heat
1. When a request for electric heat is received, the
AFC communicates to the EHC how much de-
mand for auxiliary heat is being requested
2. The EHC determines the number of elements that
will be used for this request and sends a message
to the AFC for proper airflow. (The EHC deter-
mines the amount of heat available per stage by
either factory programming or by the kw jumper
position)
3. The AFC sends a command to the serial communi-
cating blower motor to run proper airflow and close
the blower interlock relay on the EHC.
4. Humidifier contacts close.
5. As demand from the thermostat increases, the EHC
will communicate to the AFC the required airflow
when energizing additional relays.
AM8 Sequence of Operation
Abbreviations
• AFC = Airow Control
• EVC = Expansion Valve Control
• EEV = Electronic Expansion Valve
• EHC = Electric Heat Control
• HHC= Hydronic Heat Control
This unit as shipped is ONLY compatible with Trane
and American Standard communicating thermo-
stats and OD units. (24VAC thermostats cannot be
used)
With the addition of a BAYCC24VK01 accessory, this
unit can be compatible with a 24VAC single or
multistage heat pump or air conditioner.
The installing and servicing technician should have an
understanding of the sequence of operation to be
able to properly setup and diagnose functions of
the air handler.
See unit, auxiliary heat, and field wiring diagrams
for additional information.
Continuous Fan
IMPORTANT: If the indoor air exceeds 60% relative
humidity or simply feels uncomfortably humid, it is
recommended that the indoor fan only be used in
the AUTO mode.
1. When a fan request is received from the ther-
mostat, the AFC sends a command to the serial
communicating blower motor to run. Airflow can be
adjusted through the thermostat
2. Humidity Control – When enabled in the thermo-
stat, this feature will disable any blower off delays
and disable continuous fan mode when the humid-
ity is above the dehumidification setpoint. This will
help prevent coil condensation from being evapo-
rated back into the air stream.
Cooling mode
1. When a request for 1st stage cooling is received,
the AFC sends a command to the serial commu-
nicating blower motor to run at 1st stage cooling
airflow. (Delay profiles from the thermostat may
change blower motor timing and actual airflow
demand)

TAM85
NOTE: The EHC has “lead-lag or rotating” logic built in
that energizes the electric heat relays based upon
cycle counts. To verify operation of all heating
elements, switch thermostat to Emergency Heat
and raise the setpoint of the thermostat at least 5
degrees above the actual room temperature.
Hydronic Heat
1. When the request for hydronic heat is received, the
AFC communicates to the HHC how much auxil-
iary heat is being requested
2. The HHC will close the K1 relay contacts that en-
able the boiler or circulating pump to start.
3. The HHC sends a signal to the AFC when the inlet
water temperature reaches 100 degrees for a
maximum of 60 seconds, and then determines the
amount of airflow needed for the heat demand.
4. The AFC sends a command to the serial communi-
cating blower motor to run at the requested CFM.
5. Humidifier contacts close.
6. As demand from the thermostat increases, the
HHC will communicate to the AFC matching air-
flow requirements.
Defrost
1. The OD unit will initiate defrost and send a mes-
sage to the AFC.
2. The AFC will communicate to the EVC that the OD
is in defrost and the EVC will start to control the
correct superheat.
3. Electric or hydronic heat will be energized to help
temper the air. (Auxiliary heat options for defrost
can be adjusted through the Display Assembly
Configuration Menu)
Optional Condensate Switch
1. An optional OEM Condensate Switch can be in-
stalled within the unit. This switch is only available
through the National Distribution Center or Global
Parts.
2. OEM Condensate Switch contacts are Normally
Open and will close when water level inside the
unit rises. A closed switch will de-energize the OD
unit.
3. The OEM Condensate Switch is only operational
during the cooling mode and is not operational
during heating or defrost modes.
Note: Standard aftermarket condensate switches
(Normally Closed) can be wired in series with the
“External Switch” contacts on the AFC.
Important: The switch action must be selected in the
Configuration Menu section of the Display Assem-
bly to either “Disable Cool” or “Disable All”.
Freeze Protection
1. The EVC control has the ability to sense when the
indoor coil is beginning to ice. If this event should
occur, the AFC will send a message to de-energize
the OD unit.
2. The indoor blower motor will continue running to aid
in defrosting the coil.
3. After 5 minutes, the OD will be turned back on.
(*CONT900 and the 1st release of the *ZONE950
will disable the indoor blower motor and OD unit for
30 minutes)
Unit Test Mode
Unit Test Mode will exit if any demand is given to the
unit.
To enter Unit Test Mode:
1. Set System Switch on comfort control to Off
2. Scroll to the Control Menu on the Display Assembly
3. Scroll down to the Unit Test selection and push the
“Enter” key
Sequence of Unit Test Mode (OD unit is not ener-
gized during the Unit Test Mode)
1. EVC drives the EEV motor to the 1st stage position
for 5 seconds
2. EVC drives the EEV motor to the 2nd stage position
for 5 seconds
3. AFC energizes the blower at 50% and then contin-
ues to ramp until it reaches 100% cooling airflow.
4. Humidifier contacts close when the blower starts
5. EHC energizes the circuit relay(s) for 5 seconds
each in 5 second intervals.
6. All relays de-energize and the blower shuts off five
seconds after the last bank of heat is energized.
7. HHC energizes its K1 relay that interfaces with
the boiler system or circulating pump. The blower
continues to run for 30 seconds and then K1 relay
contacts open and the blower shuts off.
If an error occurs during the Unit Test Mode, the Fault
LED will flash a code and continue the test.
