TEC3000 Series Single- or Two-Stage Economizer Thermostat Controllers Installation Instructions

This option is also exposed to the BAS through the point AUX-MODE.
Commissioning Mode
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:
1.
Press the
Menu
icon.
2.
Select
Commissioning
.
3.
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:
1.
Select the output to command. Adjust the value to the desired 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.
Sensor Priority
The TEC3000 supports various sources of sensor data for use in control or display, including internal sensors,
remote sensors (connected using an analog input), or network commanded sensors. The TEC uses the highest
priority connected input (network commands followed by remote sensors and then internal sensors) for control and
display. Not all sources are available for all sensors.
Network commands operate on a timeout basis. When a network point is written to by a supervisor, the point
becomes the highest priority for 15 minutes. If a new update is written within 15 minutes, the timer is restarted for
another 15 minutes.
Available Fault Diagnostics
•
Supply Fan Faults—The TEC3000 supports a configurable Supply Fan Status feedback input that turns on
when the Supply Fan Status does not match the Supply Fan Command, and can be configured to disable
heating, cooling, and fan commands. The alarm delay is adjustable through the Fan Alarm delay setting. If the
delay is set to 0 or the binary input is not defined, this feature becomes disabled.
•
Supply Fan Runtime—The TEC3000 supports setting runtime limits on the supply fan command. When the
limit is exceeded, an alarm turns on
.
This feature is intended to be used as a maintenance reminder. Setting
the runtime limit to 0 disables this feature.
•
Supply Air Temperature Diagnostics—The TEC3000 supports diagnostics when you have a Supply Air
Temperature installed. The TEC3000 monitors the supply air. If you call for cooling or heating and the
temperature does not fall or rise by at least the supply air temperature alarm offset value within the supply air
temperature alarm delay, an alarm is generated. If the monitoring occurs while cooling, a cooling ineffective
alarm is generated. If the monitoring occurs while heating, a heating ineffective alarm is generated. If you set
the supply air temperature offset value set to 0, this alarm is disabled.
•
Zone Temperature Alarm—When enabled, the user can set a low and high temperature alarm; and if the zone
temperature rises or falls below those limits, an alarm is generated.
•
Trends—Built-in trends exist for many of the inputs and outputs for the TEC3000. These trends are viewable at
the TEC. The analog graph displays data in 15-minute increments over the previous 24 hours or a table with
the last 25 data points. Binary trends display 25 samples taken at every change of state.
