Connecting Inputs - Daikin BACnet Series Installation Manual

Connecting Inputs

The inputs for the BACnet™ Thermostat are configured for specific
functions and do not require set up in the field. Not all inputs are
required for every application.
Remote Space Temperature Sensor (optional)
Connect a 10kΩ, Type II thermistor temperature sensor to the remote
space temperature (RS) input and ground (GND) terminals. The input
includes the internal pull-up resistor. Follow the instructions supplied
with the sensor for installation.
When a remote space temperature input is connected to the BACnet
Thermostat, the remote temperature is used instead of the internal
temperature sensor.

Discharge Air Temperature
Connect a 10kΩ, Type II thermistor temperature probe to the
discharge air temperature (DAT) input. The input includes the
internal pull-up resistor. Follow the instructions supplied with
the sensor for installation.

Fan Status Switch (optional)
Connect a Normally Closed Fan Status switch to the Discharge Air
Temperature (DAT) input and ground (GND) terminals. The input
includes the internal pull-up resistor. Follow the instructions supplied
with the switch for installation.

Outside Air Temperature
Connect a 10kΩ, Type II thermistor temperature probe to the
outside air temperature (OAT) input. The input includes the internal
pull-up resistor. Follow the instructions supplied with the sensor
for installation.
