b. Press Menu > Setup > Input Setup > AI1 Offset and select the temperature offset as needed for the
sensor connected to RSEN. The options are -5°F to 5°F or -2.8°C
to 2.8°C.
• If the selected sensor is a Relative Humidity, Carbon Dioxide, or Damper feedback sensor, the Input Setup
is automatically set to 0-10 VDC. Press Menu > Setup > Input Setup > AI1 Offset and select the offset
needed for the sensor connected to RSEN. The options are -15% to 15% for Relative Humidity, -200 ppm
to 200 ppm for Carbon Dioxide, and -15% to 15% for Damper Feedback.
7. Configure the analog inputs RSEN and COS by following the same steps to set up AI1 Input Selection, AI1
Input Setup, AI1 Offset, AI2 Input Selection, AI2 Setup, and AI2 Offset.
8. Complete steps 1 -7 to re-configure the respective AI if you have to change the sensor connected to any of the
AIs. When the setup of AI1 Input Selection and AI2 Input Selection changes from resistive type (Remote Zone
Temperature and Outdoor Air Temperature) to 0-10 VDC type (Relative Humidity and Carbon Dioxide) or vice-
versa, the thermostat restarts.
Networked sensors
The TEC3000 supports sensor values supplied over a network connection. For the TEC3000 to consider the value
as reliable, the value must be written to the NET- Override network point at least every 15 minutes. Table 12
provides a list of point descriptions and the suggested write interval ranges.
Availability of AIs
For TEC3x1x-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 (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.
