Value
Sets the minimum maximum output
percentage that the controller will

request from Motor 1.
Sets the maximum output percentage
9 9 0 0 that the controller will request from
Motor 2.
Sets the minimum maximum output
percentage that the controller will
1 1 4 4 .5 5
request from Motor 2.
Selects the rpm above which the
Motor 1 will be assumed to be in an
2 2 5 5 0 0 0 0
overspeed condition and will need to be
shut down.
Selects the rpm above which the
Motor 2 will be assumed to be in an
2 2 5 5 0 0 0 0
overspeed condition and will need to be
shut down.
Selects which mode should be assigned
to the Binary output circuit, depending
F F n n s s t t
on unit type.
Boosts or attenuates the analog input
1 1
signal to compensate for long wire runs.
Rejects noise on the analog input lines
and sets up the motor control board to
0 0 .5 5
turn on if the thermostat or controller is
commanding its analog outputs on.
Sets up the tachometer function to be
compatible with the on-board motor and
1 1 8 8
for correct speed calculation and
calibration.
Sets up the on board closed loop
control to control Motor 1 with proper
0 0 .0 0 3 3
stability.
Sets up the on board closed loop
control to control Motor 1 with proper
0 0 .0 0 3 3
stability.
Sets up the on board closed loop
control to control Motor 2 with proper
0 0 .0 0 3 3
stability.
Sets up the on board closed loop
control to control Motor 2 with proper
0 0 .0 0 3 3
stability.
Sets the make value for the motor
control board triac output based on the
8 8 5 5
thermistor input.
Sets the break value for the motor
control board triac output based on the
9 9 0 0
thermistor input.
Sets the input impedance of the

This setting has to be correct for proper unit
operation of electric heat and changeover units.
A value of 1 1 should be used if no voltage level
compensation is needed (i.e., voltage peak is at
10 VDC).
Do not change this setting as this is critical to
proper unit operation.
Do not change this setting.
Do not change this setting.

Operation also depends on F F p p r r v v , A A i i 2 2 B B , and
A A i i p p u u settings.
Operation also depends on F F p p r r v v , A A i i 2 2 m m , and
A A i i p p u u settings.
Should be pre-set to "OUT" for Tracer
controllers.
