• Remote Zone Temperature—Sets up the AI to accept a resistive input when connected to one of
the six supported types of temperature sensors.
• Carbon Dioxide—Sets up the AI to accept a 0-10 VDC input when connected to a CO
2
sensor.
• Damper Feedback—Sets up the AI to accept a 0-10 VDC input when connected.
• Outdoor Air Temperature—Sets up the AI to accept a resistive input when connected to one of
the six supported types of temperature sensors.
• Supply Air Temperature—Sets up the AI to accept a resistive input when connected to one of the
six supported types of temperature sensors.
Configuring the AIs
1. Connect the required sensors to the analog inputs.
2. Press the
Menu
icon.
3. Press
Setup
.
4. Press
Input Setup
.
5. Press
AI1 Input Selection
and select the sensor that is connected to RSEN. If the selected
sensor is a Remote Zone Temperature, Outdoor Air Temperature, or Supply Air Temperature
sensor, the thermostat restarts.
6. Do one of the following after the restart based on the type of sensor you are configuring:
- If the selected sensor is a temperature sensor, do the following:
i. Press
Menu
>
Setup
>
Input Setup
>
AI1 Input Setup
and select the temperature
sensor that is connected to RSEN.
ii. 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. The following table provides a list of point descriptions and the suggested write
interval ranges.
