Reheat Configuration
All AVR applications with reheat control will have this menu item enabled, and it
must be configured appropriately to correspond to the Fume Hood/Other exhaust
valve.
Step 1:
Configure Duct Temp. Sensor (AI-1) signal
to correspond with the supply air discharge
temperature sensor that is installed and
connected to the AVR.
Step 2:
Configure Reheat Valve (AO-1) signal
type, control action, and range to correspond
with the reheat valve actuator that is connected
to the AVR.
Step 3:
Select “Update Controller” to save
changes.
6.5.3.1.6
Tuning
The Tuning window provides a logic diagram of the AVR control system as
configured for the application. The logic diagram shows how the individual control
loops interact while providing access to key parameters required for monitoring,
evaluating, and troubleshooting system performance. The factory default tuning
parameters are well-suited for the majority of AVR applications; however, changes
can be made to optimize the performance as required.
6.5.3.1.6.1
AVR PI Control Loops
The AVR6000 control system is comprised of five individual closed-loop feedback
control loops that act together to form a comprehensive room temperature and
airlfow control system. A diagram of each control loop is provided below followed
by a glossary of terms used in the control loops.
5 Reheat Configuration
Note:
Before proceeding, verify the
supply discharge duct temp sensor type
and connection to the AVR is correct.
Also verify the reheat valve actuator
signal type and connection to the AVR is
correct.
