Description
Mtr 1 High Spd
HHii 11 11008800
Sets the high-speed rpm for Motor 1. Do not exceed 2300 rpm.
Mtr 1 Med Spd
mmdd 11 777777
Sets the medium-speed rpm for
Motor 1.
Mtr 1 Low Spd
lloo 11 663322
Sets the low-speed rpm for Motor 1. Do not set under 600 rpm.
EHStg1 Mtr1
Spd
EE11mm11 00
Assigns an rpm to be associated with a
call for 1
st
stage electric heat, for
Motor 1 (only on units equipped with
electric heat).
EE11MM11, EE11MM22, EE22MM11, EE22MM22 settings are locked out
on units with electric heat.
EH Stg 2 Mtr 1
Spd
EE22mm11 00
Assigns an rpm to be associated with a
call for 2
nd
stage electric heat, for
Motor 1 (only on electric heat equipped
units).
AI High Spd Mtr
1
aahhmm11 00
Sets the maximum rpm for Motor 1 for
the maximum input value of the analog
input.
Analog inputs below the vvFFllrr setting will be
rejected.
AI Low Spd Mtr
1
aallmm11 00
Sets the minimum turn-on rpm for
Motor 1, when the analog input
becomes active.
Mtr 2 Hgh Spd
HHii 22 00
Sets the high-speed rpm for Motor 2. Blower coils have only one motor.
Mtr 2 Med Spd
MMdd 22 00
Sets the medium-speed rpm for
Motor 2.
Mtr 2 Low Spd
LLoo 22 00
Sets the low-speed rpm for Motor 2.
EHStg1 Mtr2
Spd
EE11mm22 00
Assigns an rpm to be associated with a
call for 1
st
stage electric heat, for
Motor 2 (only on electric heat equipped
units).
If the unit has only one motor, all seven speed
settings for the second motor
(HHii 22, MMdd 22, LLoo 22, EE11MM22, EE22MM22, AALLMM22,
AAHHMM22) should be set to zero.
EH Stg 2 Mtr 2
Spd
EE22mm22 00
Assigns an rpm to be associated with a
call for 2
nd
stage electric heat, for
Motor 2 (only on electric heat equipped
units).
AI High Spd Mtr
2
aahhmm22 00
Sets the maximum rpm for Motor 2 for
the maximum input value of the analog
input.
AI Low Spd Mtr
2
aallmm22 00
Sets the minimum turn-on rpm for
Motor 2, when the analog input
becomes active.
Op Mode Mtr 1
mmoodd11 rrppmm
Sets the operational mode for Motor 1.
Must be set to rrppmm for blower coil units.
Op Mode Mtr 2
mmoodd22 rrppmm
Sets the operational mode for Motor 2.
Must be set to rrppmm for blower coil units.
Mtr 1 Out
Format
ssiigg11 ppwwMM
Sets the interface type for Motor 1.
Must be set to PPWWMM for blower coil units.
Mtr 2 Out
Format
ssiigg22 ppwwMM
Sets the interface type for Motor 2
Must be set to PPWWMM for blower coil units.
Mtr 1/2 PWM
Freq.
ffrreeqq 110000
Sets the PWM frequency, for cases
when the PWM outputs are used.
On blower coil units, the PPWWMM must not be
changed.
Mtr 1 PWM Volt MM11vvll 55
Sets the PWM voltage, for cases when
the PWM outputs are used.
This setting must NOT be changed, as damage
to the motor may occur!
Mtr 2 PWM Volt MM22vvll 55
Sets the PWM voltage, for cases when
the PWM outputs are used.
This setting must NOT be changed, as damage
to the motor may occur!
Mt1 Hgh PWM
Lt
MM11hhii 9900
Sets the maximum output percentage
that the controller will request from
Motor 1.
This envelope protection value should not be
altered.
