LED Type | Label | Indication |
| (if present)* |
|
DO | LED | Indicates the ON/OFF status of the DO associated with it. A |
|
| glowing LED indicates that the DO is energized. |
|

|
Receive | RX | Indicates , when flashing, that the controller is receiving |
|
| information from the field panel. |
|
|
|
Transmit | TX | Indicates, when flashing, that the controller is transmitting |
|
| information to the field panel. |
Basic Sanity | BST | Indicates, when flashing ON and OFF once per second, that |
Test |
| the controller is functioning properly. |

Temperature Sensors
An electronic Room Temperature Sensor (RTS) or an optional auxiliary temperature sensor may be used with the Siemens BACnet Heat Pump
Room Temperature Sensor
The controller room temperature sensor connects to the controller by means of a cable preterminated at both ends with a
Mixed Air Temperature Sensor
The mixed air temperature sensor is a 10K Ω thermistor that connects to the controller at Al 5.
