2. Press Setup.
3. Press General Control Setup.
4. Press Tuning.
5. Press Temp Control Setup.
6. Select Manual PID Tuning (or any option listed in Table 10).
7. Press Save and the back arrow
to return to the previous screen.
As a result of disabling PRAC+ Automatic Tuning, you have access to different types of manual tuning that allows
modifications of tuning parameters listed under Control Setup > General in Table 13.
Note: For more details on PID/PRAC+ Automatic Control Tuning, refer to the Controller Tool Help (LIT-12011147).
Configurable binary inputs
The thermostat controller supports up to two configurable binary inputs (BIs) that you can use to add additional
features to the system. You can access Configurable Binary Inputs 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 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.
Table 10: TEC3000 tuning types
Tuning type Description
Automatic PID tuning Automatic tuning in an existing TEC3000
Deadband override When the Heating/Cooling Type = On-Off, deadband control is decoupled from PRAC+
Automatic Tuning and Min On Off Equipment Setting.
When the Heating/Cooling Type = Floating, there is no deadband in use with floating
devices. This operates the same as Automatic PID Tuning.
Manual PID tuning Manual tuning of Heating and Cooling PIDs. The manual tuning parameters are listed
under Setup > General Control Setup > Tuning in Table 13.

TEC3x3x models)
