STEINEL DCS™1.2.4
Publisher Description
This is the STEINEL DCS(TM) Commissioning App for the STEINEL Digital Control Solution(TM) line of products. The STEINEL DCS(TM) integrates load control with occupancy sensors, photo sensors and switches to provide simple code compliant solutions for lighting, plug load and HVAC integration through BACnet.
Time saving wireless commissioning is accomplished via Bluetooth connection from a Smart Phone or Tablet to a STEINEL DCS(TM) Digital Controller, which communicates to the sensors and switches by the 2 wire bus.
