Product Overview
Temperature Sensors
An electronic Room Temperature Sensor (RTS) or an optional auxiliary temperature sensor
may be used with the Heat Pump Controller—Multi-Stage.
Room Temperature Sensor
The Terminal Equipment Controller RTS connects to the controller by means of a cable
preterminated at both ends with a 6-conductor RJ-11 plug-in connector. See
Figure 1-1 for
the location of the RTS/Man-Machine lnterface (MMl) port.
Mixed Air Temperature Sensor
The mixed air temperature sensor is a 100K Ω thermistor that connects to the controller at
the screw terminals for Al 3.
For more information about Siemens temperature sensors, contact your local Siemens
Building Technologies representative.
Actuators
The actuator used with the 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.
For more information about Siemens actuators, contact your local Siemens Building
Technologies representative.
