HELIOS TEMPERATURE CONTROL BOARDS
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!


This image shows a QUAD board configuration comprising four Helios temperature control boards mounted to a chassis sized to fit into the Foxboro board slot. Since our boards are a quarter the size of the original Foxboro boards, you can have Center, Front, Side and Rear controls on this QUAD board array.

This image shows a single Helios temperature control board being used as a replacement for a single zone. The smaller Helios board is mounted to a chassis matching the size of the original Foxboro boards.
