|A special MFA controller delivers
a fully coordinated split-range adaptive temperature
control system. This MFA is able to manipulate damper,
heating, or cooling to tightly control supply air
(SA) temperature. Highly robust and adaptive, the
MFA can handle the control problems caused by changes
in operating modes, seasons, loads, and environment.
Once installed, no manual tuning is required. Standard
MFA can tightly control Mixed Air Temp, humidity,
flow, and pressure loops.
|Using MFA, zone temperature can be tightly
controlled even when there are large variations
in load, coupling factors in multiple zones,
process nonlinearity caused by wrong actuator
sizing, changing seasons and environment.
|MFA controllers are ideal to provide tight
control of all critical variables for semiconductor
HVAC systems, clean rooms, pharmaceutical
and industrial laboratories and any environment
that must be stringently controlled.
||• Easy startup and elimination
of manual tuning of controllers saves technician
time and expense,
• Better control with
no oscillation yields energy savings,
Reduced wear and tear on actuators lengthens equipment
• Tighter control increases user
comfort levels and allows Building Control suppliers
to address more stringent user demands, and
• Direct PID replacement with easily embedded
