Frequently Asked Questions
What makes the M7 technology better than older systems?
M7 technology replaces mechanical pressure and temperature switches with sophisticated electronic sensors. This means there are no moving parts to wear out, providing more accurate readings and significantly improving reliability and performance.
Is this control system difficult to install?
The BP501G1 is designed with built-in connectors and simplified wiring to make installation as easy as possible. However, due to the electrical work involved (240V), we recommend that a qualified spa technician performs the installation and programming.
Can I control my hot tub with my smartphone?
Yes, this system is Wi-Fi ready. By purchasing the separate Balboa Wi-Fi Module (part #51159), you can connect the control box to your home network and manage your spa's functions from your phone or tablet.
Will this work with my current topside control panel?
The BP501G1 is compatible with a wide range of Balboa's TP and SpaTouch series control panels. Please check your existing panel's model number against our compatibility list or contact our support team to ensure it will work with your setup.
