Comments
Eliminates manual tuning and
seasonal re-tuning
Eliminates manual tuning,
improves control and energy
savings
Meets most VAV applications
Single Analog Input (AI) to Analog
Output (AO) or Binary Output
(BO)
Flow differential control
Series or parallel
Staged heat or normally
open/normally closed valves
Normally open or closed valves
Flexible flow setpoint specification
23,000 step resolution
Detects damper travel stops
Sets damper stroke time
Set via HVAC PRO™ software for
either direction to close
Allows firmware code upgrade
without removing the VMA
Provides standard measure of
control loop performance over
time
Only for single duct applications
Allows air handler reset and flow
diagnostics
Indicates shaft slippage
