Siemens BACNET 125-699 사용자 설명서

Siemens Building Technologies, Inc. 

The controller has several Light Emitting Diode (LED) indicators. (Figure 1). Table 2 lists the 
LED types and what they indicate. 

DO 

LED 1–LED 8 

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 

Test 

BST 

Indicates, when flashing ON and OFF once per second, that 
the controller is functioning properly. 

* Some LED labels may be hidden by the controller cover. 

An electronic Room Temperature Sensor (RTS) or an optional auxiliary temperature sensor 
may be used with the Siemens BACnet Heat Pump Controller—Multi-Stage. 

The controller room temperature sensor connects to the controller by means of a cable 
preterminated at both ends with a 6-conductor RJ-11 plug-in connector. See Figure 1 for the 
location of the RTS/Human-Machine lnterface (HMl) port. 

The mixed air temperature sensor is a 10K 

Ω thermistor that connects to the controller at Al 

5.

Building Technologies representative. 

The actuator used with the Siemens BACnet Heat Pump Controller—Multi-Stage may be an 
optional floating control or 0 to 10V spring return electronic damper motor that is powered 
through the controller to position an outside air damper.
