Note:
• Ensure the Bluetooth Adapter is installed away from heating
source, direct sunlight, dripping water, dusty environment.
• Avoid any obstruction around the adapter that impacts
Bluetooth communication.
• Interface cable ordered separately for the respective controller
to be used for connecting Bluetooth Adapter to Controller.
Power up sequence and connection with mobile application:
Function Description Illustration LED info
• White – Blue – Red – Green
LED blinking in sequence
indicates power up
initialization.
• After few seconds, Green
LED rapid flashes indicating
controller detection is in
progress.
• Green LED slow flashes (1s/1s)
• Red LED rapid flashes.
Power-up

• LED turns to constant Blue
indicating Bluetooth is
connected.
1. Ensure that the module is connected to the mobile app after final power up and installation to finalize the setup properly. If the
module is not connected after final power up at customer's site, the module will log the data without the correct time stamp.
2. If the Bluetooth Adapter is changed from one controller model to another (ex: ERC112C to ERC112D or EETa 3W), all the logged
data from previous controller are erased and start logging afresh from new controller. The data from previous controller is retained
if one code no. is changed to another code no. within the same controller model.
