Control
The control provides dedicated contacts to operate the T-T input of an oil primary control.
Rating shall be class 2 - 24 VAC pilot duty @ 24 VAC (< 200mA).
Power
The switched 120VAC power from the LIMIT switch passes through the board between Pins 1&2
of connector P1.

All installations and services must be performed by qualified service personnel.
7
Compressor contactor
The control provides switched 24VAC to operate a compressor contactor. Rating shall be class
2 - 24 VAC pilot duty @ 24 VAC (< 200mA).
EAC (electronic air cleaner)
The control provides a 120VAC output for an electronic air cleaner. This output is energized
whenever the fan motor is energized (either low, heat or cool speed). Connection is made via male
quick connect terminal labeled "EAC".
Humidifier
The control provides a 120 VAC output for a humidifier. Connections are made to a male quick
connect terminal labeled "FAN".
Status LED
A red LED is provided to indicate any thermostat input has been recognized by the microprocessor
on the control. See Diagnostic Features for a function description of operation.
Thermostat Input LEDs
Four green LEDs are placed beneath their respective thermostat connections (W, Y, G and DEHUM)
and operate whenever a call is present. See Diagnostic Features for a function description of
operation.
Motor CFM LED
This green LED will flash once for every 100CFM the blower is producing.
E. Operating Modes
Standby Mode
All outputs are off and the control is waiting for a thermostat demand. The thermostat inputs, and
limit switch are continuously monitored. The control initiates action when a thermostat call is
received or limit switch opens.
Fan Mode
A call for fan ("G") is received from the thermostat. If no other mode is calling for blower operation,
the control will choose a “Low” speed value from the position of DIP switch SW1 positions 4 through
6, as shown in the CFM Tables and operate the fan at that speed. The fan mode will be operated as
long as the "G" input is calling and neither the Heat mode nor the Cool mode is calling for blower
operation. When the Heat and Cool modes call for blower operation, their respective outputs will take
over after their respective turn-on time delays have expired. The speed Output is present until the
fan call is satisfied.
Cooling Mode
A call for cool ("Y") is received from the thermostat. If the heat mode is not active or the anti-short
cycle delay is not in effect, the control will energize the “CC” terminal. After a 10 second delay
blower ramps up to the “COOL” speed determined by the position of DIP switch SW1 (positions 4
through 6) determine a speed as shown in CFM Tables.
When the call for cool is satisfied, the “CC” terminal is de-energized and the cooling off delay of 45
seconds is started. Forty-five seconds later the blower speed ramps toward zero and the control
reverts to Standby Mode.
Dehumidification Operation
If a call for dehumidification is received while the Cool Mode is active, blower speeds will be
reduced. The speed value will be selected from the DEHUM column of the CFM Tables. This input
may only be used on systems using a thermostatic expansion valve (TXV) on the evaporator.

All installations and services must be performed by qualified service personnel.
8
Anti-Short Cycle Operation
To prevent compressor short cycling, a call for cooling will be ignored for four minutes after the
termination of any cooling call. The anti-short cycle delay is also in effect at power-up.
Heat Mode
When a call for heat ("W") is received from the thermostat, if the “Cool” mode is not already active,
the “T-T” terminal is energized and the blower on delay is started. The on-off pattern of DIP switch
SW2 (positions 1 and 2) select one of four blowers on delay values (see Table 1). When the delay
time has elapsed, a speed value is read from DIP switch SW1 positions 1 through 3 (see the CFM
Tables) and the blower is ramped up to that speed. The 2-Stage control will be operated by t-stat
through W1 and W2. For 2-stage control with a single stage t-stat, call for heat will go through W2.
When W2 is energized, low fire is activated for 15 minutes. If a call for heat still exists, high fire will
be activated and will continue until the demand for heat has been satisfied.
Counterflow units, in addition, will run at a low blower speed shortly after the burner is brought on.
They will continue at that speed until the delay time has elapsed.
The control remains in steady heat mode until the thermostat is satisfied. When the call for heat
signal is removed, the “T-T” terminal is de-energized and the blower off delay is started. The on-off
pattern of DIP switch SW2 (positions 3 and 4) select one of four blower off delay values (see Table
1). When the delay time has elapsed, the blower is ramped toward zero.
Table 1: ON and OFF Blower Delay Time Switch Settings
Motor lower Speed
Three blower speed outputs are provided. A “G” call for fan will provide the Low speed only. A “W”
heat call will provide the Heat speed only. A “Y” cooling call will provide the Cool speed only.
In the case of thermostat calls for “Y” and “W” together, blower speed selection will be determined by
the input that was first initiated. In the case where the control is in a cooling mode with both “Y” and
“W” inputs energized and then the “Y” input is removed, the cooling blower off time will be executed
prior to the control switching into a heating mode. In the case where the control is in a heating mode
with both “Y” and “W” inputs energized and then the “W” input is removed, the heating blower off
time will be executed prior to the control switching into a cooling mode. In the case where a call for
fan “G” already exists and either a “W” or a “Y” call is initiated, the blower speed will switch to the
respective “W” or a “Y” speed following the blower on delay for that call. Six dip switches select
Speed values for heat, cool, fan and dehumidification blower speeds (see the CFM Tables).
lower On and Off Delays
Four Heat blower on and four blower off delays are selected by two dip switches for each function.
Refer to Table 1 for specific delay values.
Counter Flow Mode
Counter Flow Operation will be allowed if JW10 is cut. If JW10 is not cut, the control will not perform
any of the Counter Flow Operation as described below. Counter Flow Operation is only valid when a
call for Heat is present. Counter Flow Operation will bring the blower on at a defined low speed at a
defined time between the enabling of the burner and the selected turn on time delay. Turn on delay
times for the Counter Flow Operation are defined in Table 1.

All installations and services must be performed by qualified service personnel.
9
Once the selected lower On Delay time has be reached, the blower operation will change to the
operation described in Motor lower Speed.
Speed Selection Values
Three dip switches select 8 cooling speeds. Dependant fan, and dehumidification speeds are
selected by the same switches, their tabular values are enacted when their function is called. Three
additional dip switches select 8 heating speeds which are enacted when heat is called. This allows
independent selection of heating and cooling capacity parameters. See the CFM Tables for speeds.
F. CFM TABLES
The following tables contain blower speed settings and their respective air flow rates for the ECM blower
motor. To change air flow rates from that of the shipped settings, use the respective SW1 dipswitch on
the furnace’s integrated control board (see Figure 3).
