16

NS zone sensor.

This sensor is required if you do not control from the RA-T sensor.

17

Use a NS sensor with a built-in humidity sensor for dehumidification or humidification control if the ZN-H sensor is not connected to input 1 on the IOM3711

Use a NS sensor with a built-in CO2 sensor for Demand Control Ventilation if the RA-CO2 sensor is not connected to input 2 on IOM3711.

You can assign additional NS sensors to address 199-206 or IOM3711 address 4. You can connect up to eight NS8000 sensors. You can connect up to 10 devices on the SA bus.

Wire the sensor bus to any other network sensors in a daisy-chain configuration.

Optional: The connector is located on the back of the sensor.

18

Return air temperature

RA-T

TE-6311M-1

Optional: Use this input to control instead of a zone temperature sensor. If a zone temperature sensor is present it takes priority and the RA-T monitors only.

19

Mixed air damper feedback

MAD-FB

n/a

Optional: Use this input when you want Title 24 economizer fault detection diagnostics as part of the unit sequence. It is assumed the actuators connected to the economizer have a voltage feedback signal. Input range is adjustable but assumed to be voltage.

20

Outside air temperature.

OA-T

TE-6313P-1

Required: Use this input if you have economizer control. This input is for a hardwired sensor. The controller has the option to data share an outside air temperature to the controller.

21

Mixed air temperature

MA-T

TE-6315M-1

Required: Use this input for low temperature limit control if you have proportional heating or cooling and an economizer. If you have staged heating and cooling, and you do not have water, you can use a supply air temperature for the economizer low temperature limit control control.

22

Supply air temperature

SA-T

TE-6311M-1

Required: Use this input if you have an economizer and no mixed air temperature.

23
