Helios Temperature Control Boards are a direct replacement for the obsolete Foxboro Temperature Control Boards.

Each Helios Temperature Control board is much smaller in size, and each board has all programing (on each board) for Center, Front, Side, and Rear controls.  Just simply select the appropriate jumper to ‘address’ your Helios board for your desired zone.

Any single Helios Temperature Control Board comes with all mounting hardware to fit into the OEM Foxboro board slot.

You can also purchase a Helios ‘QUAD’ board that is a single board – the same size an one original Foxboro board – that will replace all four Foxboro zones, on one board!
