to bring the zone to the desired occupied setpoint when the scheduled occupancy period begins.
Occupant comfort is ensured while automatically minimizing energy usage. This algorithm creates
a model of the zone being controlled and automatically determines when to start the equipment
before the scheduled transition to Occupied. The start time automatically adjusts daily to minimize
the time between reaching setpoint and entering Occupied state.
Note:
Optimal Start does not work when the schedule source is set to External.

Enabling the motion sensor (TEC3x12, TEC3x13 Models)
About this task:
By default on models with integral motion sensing capability, the motion sensor is enabled with a
default timeout of 15 minutes from the last detection of motion in the zone. On models without an
integrated sensor, the default timeout is still 15 minutes, but it only is applied when one of the two
configurable binary inputs is set to be a motion sensor (see
for informa-
tion on configuring the binary inputs). To disable motion sensing capabilities, set the Motion Sensor
Timeout to 0 minutes. See Table 8 to view the available setpoints. See Table 13 to view the setpoint
values. To adjust the motion sensor timeout:
1. Press the
Menu
icon.
2. Press

.
3. Press

.
4. Press
Motion Sensor Timeout
and adjust accordingly.

PID/PRAC+ automatic control tuning
About this task:
The TEC3000 features advanced proportional-integral-derivative (PID) control algorithms to max-
imize control performance while minimizing excessive cycling and wear on the equipment. PID is
used in conjunction with a Multi-Stage Controller (MSC) for all occupied and standby control.
Additionally, the PID features Johnson Controls proprietary PRAC+ (Pattern Recognition Adaptive
Control) 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
Setup
.
3. Press
General Control Setup
.
4. Press
Tuning
.
5. Press
