Availability of AIs
For TEC3x2x-1x-xxxx models, only the RSEN and COS
inputs are available for connection.
Priority for configurable AIs
You cannot set any two AIs to the same function or
sensor type for any of the inputs. If two or more AIs are
configured as the same, the first configured input is used
and the others are ignored. For example, if RSEN and COS
are both configured as Relative Humidity, only RSEN is
used and COS is ignored.
Priority for overall sensors data sources
The TEC3000 supports various sources of sensor data
for use in control or display, including internal sensors,
remote sensors that connect using an analog input, or
network commanded sensors. The TEC uses the highest
priority connected input, which consists of 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 the
supervisor writes a new update within 15 minutes, the
timer restarts 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 that you can configure
to disable heating, cooling, and fan commands. You
can adjust the alarm delay with the Fan Alarm delay
setting. If the delay is set to 0 or if you do not define
the binary input, this feature becomes disabled.
• Supply Fan Runtime—The TEC3000 supports setting
runtime limits on the supply fan command. When the
supply fan exeeds the runtime limit, an alarm turns on.
This feature acts 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 generates.
If the monitoring occurs while cooling, a cooling
ineffective alarm generates. If the monitoring occurs
while heating, a heating ineffective alarm generates. If
you set the supply air temperature offset value set to 0,
this alarm disables.
• 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
generates.
• 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.
