Constant Airflow Motors (ECM)
For installations where constant air delivery is
critical or where external static pressure drop can
vary greatly (such as with high MERV value filters)
the SV series is offered with a constant air flow
ECM motor option. This option provides ECM
motor efficiency combined with a constant air
delivery across a wide range of external static
pressures. These motors dynamically adjust their
power output to precisely match the desired air
flow on a pre-programmed fan curve. Additionally
these motors feature:
1. A low CFM ventilation feature that circulates
air at 70% of full load when fan only is called.
2. A passive dehumidification mode that reduces
air flow during a cooling call when
dehumidification is also required – this
reduces the sensible heat ratio of the cooling
coil and extends cooling run time to more
effectively dehumidify. (refer to the ECM
Interface Board section of this manual)
3. 3 speed settings per model. Units are factory
set to “NORM” but can be field adjusted to “+”
to increase CFM by 15% or to “-“to reduce CFM
by 15%. (refer to the ECM Interface Board
section of this manual)
4. A “TEST” mode that operates the motor at a
70% torque setting. This setting can be used to
diagnose programming problems in the motor
itself. (refer to the ECM Interface Board
section of this manual)
5. A CFM indicator light that provides a blink for
each 100 CFM of air delivered (note that this
blink code is approximate and should not
replace test and balancing).
Refer to the constant air flow motor performance
tables for heat pump blower performance with the
constant air flow motor option.
