Password Enable (
PAS.E) — This variable enables or dis-
ables the use of a password. The password is used to restrict
use of the control to change configurations.
Service Password (
PASS) — This variable is the 4-digit nu-
meric password that is required if enabled.
VFD Configurations — There are two sub-menus under
the Configuration menu, Configuration
 IAQ  S.VFD and
Configuration
 IAQ  E.VFD. These configurations are for
the supply fan or optional exhaust fan variable frequency
drives (VFDs). These sub-menus contain the configurations re-
quired for the Supply Fan and Exhaust Fan VFDs. This section
defines the configurations in these sub-menus. See Table 66
and 67. Further information on VFD configurations can be
found in Appendix D.
SUPPLY FAN VFD CONFIGURATION — The sub-menu
that contains these configurations is located at the local display
under Configuration
 IAQ  S.VFD.
VFD1 Nominal Motor Volts (
N.VLT) — This configuration
defines the nominal motor voltage. This value must equal the
value on the motor rating plate. This value sets the maximum
drive output voltage supplied to the motor.
NOTE: The VFD cannot supply the motor with a greater volt-
age than the voltage supplied to the input of the VFD. Power to
the VFD must be cycled in order for a change to this configu-
ration to take effect.
VFD1 Nominal Motor Amps (
N.AMP) — This configura-
tion defines the nominal motor current. This value must equal
the value defined in the Supply Fan Motor Limitations
Table 21. Power to the VFD must be cycled in order for a
change to this configuration to take effect.
VFD1 Nominal Motor Freq (
N.FRQ) — This configuration
defines the nominal motor frequency. This value must equal
the value on the motor rating plate. This value sets the frequen-
cy at which the output voltage equals the Nominal Motor Volts
(N.VLT). Power to the VFD must be cycled in order for a
change to this configuration to take effect.
VFD1 Nominal Motor RPM (
N.RPM) — This configura-
tion defines the nominal motor speed. This value must equal
the value on the motor rating plate. Power to the VFD must be
cycled in order for a change to this configuration to take effect.
VFD1 Nominal Motor HPwr (
N.PWR) — This configura-
tion defines the nominal motor power. This value must equal
the value on the motor rating plate. Power to the VFD must be
cycled in order for a change to this configuration to take effect.
VFD1 Motor Direction (
M.DIR) — This configuration sets
the direction of motor rotation. Motor direction change occurs
immediately upon a change to this configuration. Power to the
VFD need NOT be cycled for a change to this configuration to
take effect.
VFD1 Acceleration Time (
ACCL) — This configuration sets
the acceleration time from zero to maximum output frequency.
Power to the VFD must be cycled in order for a change to this
configuration to take effect.
VFD1 Deceleration Time (
DECL) — This configuration sets
the deceleration time from maximum output frequency to zero.
Power to the VFD must be cycled in order for a change to this
configuration to take effect.
VFD1 Switching Frequency (
SW.FQ) — This configuration
sets the switching frequency for the drive. Power to the VFD
must be cycled in order for a change to this configuration to
take effect.
EXHAUST FAN VFD CONFIGURATION — The sub-
menu that contains these configurations is located at the local
display under Configuration
 IAQ  E.VFD.
VFD2 Nominal Motor Volts (
N.VLT) — This configuration
defines the nominal motor voltage. This value must equal the
value on the motor rating plate. This value sets the maximum
drive output voltage supplied to the motor.
NOTE: The VFD cannot supply the motor with a greater volt-
age than the voltage supplied to the input of the VFD. Power to
the VFD must be cycled in order for a change to this configu-
ration to take effect.
VFD2 Nominal Motor Amps (
N.AMP) — This configura-
tion defines the nominal motor current. This value must equal
the value defined in:
• the High-Capacity Power Exhaust Systems Motor Limi-
tations table (Table 22) if BP.CF=4
• the Supply Fan Motor Limitations table (Table 21) if
BP.CF=5
• the Optional VFD Power Exhaust Motor Limitations
table (Table 68) if BP.CF=3
