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.

and TEC3x3x models)

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
