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 Inputs are accessed through Settings > Control 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.
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, motion detected by the sensor is ignored. Note that
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 Table 9.
Deadband Override There is no deadband in use with proportional devices. This operates in the same way
as Automatic PID tuning.
Manual PID Tuning Manual tuning of Heating and Cooling PIDs. The manual tuning parameters are listed
under Control Setup > Tuning in Table 10.
