Siemens RDB160BNU : Fan Coil Unit Room Thermostat with BACnet MS/TP Communication
- BACnet MS/TP Communication
- Operating voltage: AC 24 V
- Fan: 1, 2, 3-speed or DC 0...10 V* (automatic or manual)
- Valve actuators: On/off, 3-position or DC 0...10 V*
- Electric heater: On/off
- Built-in temperature sensor
- 3 configurable inputs for external room/return air temperature, supply air temperature limitation, heating/cooling changeover, window contact, and occupancy sensor
- Operating modes: Comfort, Standby (Economy), OFF, and mold protection
- Room temperature control: Based on built-in temperature sensor or room/return air temperature
- Heating/cooling changeover: manual, or automatic via water temperature sensor or digital input
- Supply air temperature limitation
- Automatic valve exercise
- Backlit LCD
*Up to 2 DC 0…10 V control outputs are available i.e., the control of a DC fan, DC cooling valve, and DC heating valve is not possible
