Configurable Binary Inputs - Johnson Controls TEC3000 Series Installation Manual

Multi-Stage Controller (MSC) for all occupied and standby
control.
Additionally, the PID features Johnson Controls
proprietary Pattern Recognition Adaptive Control (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,
complete the following steps:
Press the Menu icon.
1.
Press Setup.
2.
Press General Setup.
3.
Press Tuning.
4.
Press Reset PID Tuning and select Yes.
5.
6. Press Save and the back arrow 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, complete the following steps:
Press the Menu icon.
1.
Press Setup.
2.
3. Press General Setup.
4. Press Tuning.
5. Press Temp Control Setup.
6. Select Manual PID Tuning (or any option listed in
Table 11).
7. Press Save and the back arrow to return to the
previous screen.
Result
As a result of disabling PRAC+ Automatic Tuning, you get
access to different types of manual tuning that you can
modify. These tuning parameters are listed under Control
Setup > General in Table 14.

Tuning type Description
Automatic PID Automatic tuning in an existing
Tuning TEC3000
Deadband There is no deadband in use with
Override proportional devices. This operates in
the same way as Automatic PID tuning.
Manual PID Manual tuning of Heating and Cooling
Tuning PIDs. The manual tuning parameters
are listed under Setup > General Setup
> Tuning in Table 14.

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
22 TEC3000 Series Proportional Fan Coil Thermostats Installation Guide
Inputs are accessed through 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.
• Service—Input from the equipment to display a service
warning on the thermostat
• Dirty Filter—Input from the equipment to display a
dirty filter fault on the thermostat
• Motion NC—External motion sensor with a closed
contact output when no motion is detected
• Motion NO—External motion sensor with an open
contact output when no motion is detected
• Temp Occ—Trigger to place controller into Temporary
Occupancy mode
• Occupancy—Direct override of Occupied and
Unoccupied
• Supply Fan Status—Input from the equipment to
display a Supply Fan Fault. When Fan Alarm Action is
set to Shutdown and the Supply Fan Fault is active, the
TEC3000 disables the fan, heating, and cooling. When
the Fan Alarm Action is set to Enable and the Supply
Fan Fault is active, the TEC3000 allows the fan, heating,
and cooling to operate during the Supply Fan Fault.
Setting both BIs to the same function is not supported for
Occupancy, Fan Lock, Open Door, and Open Window. If
both BIs are set the same for those four, BI2 is ignored
and only BI1 is used.
The Open Door option works in conjunction with a motion
sensor, either built into the TEC or connected to another
BI configured for Motion NO/NC mode. When the door
is open, the sensor ignores detected motion. Opening
the door does not stop an Occupied period started by the
motion sensor prior to opening the door.
The polarity of the inputs are provided in the following
table.
