PID/PRAC+ Automatic Control Tuning
The TEC3000 features advanced proportional-integral-derivative (PID) control algorithms to maximize control
performance while minimizing excessive cycling and wear on the equipment for all occupied and standby control.
Additionally, the PID features Johnson Controls proprietary PRAC+ automatic tuning, which continuously tunes the
controller parameters to automatically optimize the control performance to match the equipment and zone. By
default, PRAC+ is enabled and immediately begins to tune. To reset tuning at any time to the factory defaults:
1.
Press the
Menu
icon.
2.
Press
Control Setup
.
3.
Press
Tuning
.
4.
Press
Reset PID Tuning
and select
Yes
.
5.
Press
to save and
to return to the previous screen.
PRAC+ automatic tuning can also be disabled. When disabled, the controller parameters remain at their last values
until automatic tuning is re-enabled. To disable automatic tuning:
1.
Press the
Menu
icon.
2.
Press
Control Setup
.
3.
Press
Tuning
.
4.
Press
Temp Control Setup
.
5.
Select
Manual PID Tuning
.
6.
Press
to save and
to return to the previous screen.
As a result of disabling PRAC+ Auto Tuning, you have access to different types of manual tuning that allows
modifications of tuning parameters listed under
Control Setup > General
Note:

Configurable Binary Inputs
The thermostat controller supports up to two configurable binary inputs (BIs) that can be used to add additional
features to the system. Configurable Binary Inputs are accessed through
Settings > Control Setup > Inputs
. Both
BIs can be configured to support the following options:
•
Disabled—Sets the binary input to an unused state. When disabled, you can use the binary input for
monitoring-only without affecting the thermostat functionality.
•
Open Window—Sensor to shut down control if a window is opened. The controller disables control 60 seconds
after detecting an opened window.
•
Open Door—Works in conjunction with the Motion NO/Motion NC sensor to control occupancy
•
Fan Lock—Air Proof switch input to shut down control if no airflow is detected within 10 seconds of turning the
fan on. Fan Lock must be manually reset from the Faults menu.

Deadband Override
There is no deadband in use with proportional devices. This operates in the same way
as Automatic PID tuning.
Manual PID Tuning
