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 Table 12.

enter that state.
Commissioning mode
About this task:
The thermostat controller has a built-in commissioning
mode, which is designed to allow you to quickly test
equipment wiring and functionality. Commissioning mode
temporarily disables the control logic, and allows you to
manually command any individual output. Commissioning
is designed to be the last step of the installation process
after configuring the controller for the equipment being
controlled, and the available options in commissioning
mode are dependent on the controller configuration. To
enter commissioning mode, complete the following steps:
1. Press the Menu icon.
2. Press Setup.
3. Select Commissioning.
4. Confirm that the selection was intentional. (The
control is overridden upon selecting Confirm).
Individual outputs can be commanded through this
interface. For binary outputs, the options are Off or On;
for analog outputs, they can be commanded from 0 to
100%. Whenever a control output is turned on, the fan
is engaged for safety purposes. To command an output
from the Commissioning menu, complete the following
steps:
1. Select the output to command. Adjust the value to
the preferred output and press Save. The output
immediately changes to that value.
2. Restore the value to the original setting and press
Save once again to complete testing that output.
Pressing the back icon from the main commissioning
menu or allowing the menu system to time out and return
to the home screen ends commissioning and puts the
control logic back in control of the outputs.
Dehumidification control
About this task:
Dehumidification operates when the zone humidity
increases above the humidity setpoint and the controller
is in a satisfied state with no active call for cooling or
heating. When dehumidification is active, the cooling
device controls to the humidity setpoint, and the heating
device reheats the zone in order to keep the temperature
at setpoint.
The TEC3000 controller supports dehumidification control
under the following configurations:
• RTU with an auxiliary dehumidifier wired to Aux output
• Heat pump with an auxiliary dehumidifier wired to Aux
output
• RTU with hot gas reheat installed and wired to AUX
output
To enable dehumidification control, complete the
following steps:
1. Press the Menu icon.
2. Press Setup.
3. Press General Setup.
4. Press Dehum Enable and select Yes.
5. Press Save and the back arrow to return to the
previous screen.
6. Press Dehumidification Sequence Mode and select
the applicable dehumidification sequence option
based on the type of equipment.
Dehumidification Sequence Modes:
• Simple dehimidification—select this option if you
use an external or auxiliary dehumidifier wired to the
thermostat’s Aux output.
• Hot gas reheat dehumidification—select this option if
the equipment type is RTU with hot gas reheat and the
HGR valve is wired to the thermostat’s Aux output.
• None—select this option if no dehumidification
equipment is present.
Only one dehumidification process is active at a time.
To adjust the dehumidification setpoint, complete the
following steps:
1. Press the Menu icon.
2. Press Setpoints.
3. Press Dehumidification
