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 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 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.
