TEC3000 Series On/Off or Floating Fan Coil and Zoning Thermostat Controllers with Dehumidification
Capability Installation Instructions
Enabling the Motion Sensor (TEC3x11-00-000,
TEC3x13-00-000 Models)
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 section Configurable
Binary Inputs for information on configuring the binary
inputs). To disable motion sensing capabilities, set the
Motion Sensor Timeout to 0 minutes. See Table 4 to
view the available setpoints. See Table 6 to view the
setpoint values. To adjust the motion sensor timeout:
1. Press the Menu icon.
2. Press Schedule.
3. Press Schedule Options.
4. Press Motion Sensor Timeout and adjust
accordingly.
5. Press to save and to return to the
previous screen.
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. 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 Control Setup.
3. Press General.
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 General.
4. Press Auto PID Tuning Enable and select No.
5. Press to save and to return to the
previous screen.
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. Both BIs can be
configured to support the following options:
• Occupancy – Direct override of Occupied and
Unoccupied
• Temp Occ – Trigger to place controller into
Temporary Occupancy mode
• Motion NO – External motion sensor with an open
contact output when no motion is detected
• Motion NC – External motion sensor with a closed
contact output when no motion is detected
• Dirty Filter – Input from the equipment to display a
dirty filter fault on the thermostat
• Service – Input from the equipment to display a
service warning on the thermostat
• Fan Lock – Air Proof switch input to shut down
control if no airflow is detected within 10 seconds
of turning the fan on
• Open Door – Works in conjunction with the Motion
NO/Motion NC sensor to control occupancy
• Open Window – Sensor to shut down control if a
window is opened. The controller disables control
60 seconds after detecting an opened window.
Setting both BIs to the same function is supported for
all except 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 is designed to work in
conjunction with a motion sensor, either built into the
TEC or connected to another BI configured for Motion
NO/NC mode.
