Rejects noise on the analog input lines and sets
up the motor control board to turn on if the
.
0 5
thermostat or controller is commanding its
analog outputs on.
Sets up the tachometer function to be
18
compatible with the on-board motor and for
correct speed calculation and calibration.
Sets up the on board closed loop control to

control Motor 1 with proper stability.
Sets up the on board closed loop control to

triac output based on the thermistor input.
Sets the input impedance of the thermistor

input.
3
Sets the ramp rate for Motor 1, in % per second.
3
Sets the ramp rate for Motor 2, in % per second
Sets the acceleration factor for the electric heat
2
inputs.
Sets the maximum ramp time for both Motor 1
15
and Motor 2 (in seconds).
Selects how long the fan needs to stay on after
15
an electric heat request has been turned off.
Selects whether to use the on-board locked
on
rotor protection function.
This function protects settings on the board that
on
affect the safety of the electric heat system.
This function shortens the ramps for faster unit
commissioning and auto-resets to off after
off
approximately 15 minutes of power-on
operation.

Is used to force faster ramps when electric heat
is requested.

Not used on fan-coil unit.
This will shut down the affected motor, if

To aid in commissioning of the unit, for
approximately 10–15 minutes, the ramps will be
shortened to quickly observe proper unit
behavior and response to speeds.
