Used: Came out of a hot tub that froze.
Lots of youtube videos to show how to install: part number Balboa 50350 model (wi-fi g module (20)) Works great on the test bench at less than 1/2 the price.
System & WiFi Router Requirements:
bwa communicates over a 2.4GHz home network supporting 802.11b/g/n wireless technology. Note: 5GHz networks are not supported.
Standard wireless setup supports only home network routers configured to use open (no security) or WEP/WPA/WPA2.
A WiFi signal strength of -50 dBM or better is highly suggested to ensure non-interrupted cloud service. If you need to move your module closer to the router, you can order an extension cable from 7ft. to 100 ft in length (7, 25,50,100):
bwa™ wireless access is not supported on: Guest networks/Hotspots that use a portal page to login.
If using a dual band router 2.4/5 GZ, then separate the networks and connect to the 2.4 GZ
Enterprise access points configured to require certificates or some other form of enterprise authentication (aka "802.1X", "RADIUS", or "WPA/WPA2 Enterprise").
You need a Balboa BP main spa pack/control system to use this Wifi Module for your spa.
Can use wifi with BP Series Balboa control systems including BP501, BP501X, BP601, BP2000 and BP2100.
To install n a BP500 or BP600 spa pack/system, you may need a y-cable that is plugged into the circuit board (splitter) and the WiFi Cable is plugged into the first end of the Y-Cable panel jack and the Control panel is installed in the second end of the Y-Splitter cable.
