Balboa M7 temperature sensor for remote heaters

This M7 temperature sensor has a 90 cm cable, and is typically used with heaters that are separated from the main spa control system, instead of being directly attached to it. These heaters are typically used with GS100 and BP200 UX control systems, but could potentially be connected to any Balboa M7 system.

The M7 system uses two identical temperature sensors placed at either end of the heater. The sensors have two-pin plugs which connect to sockets on the motherboard of the control system.
