Some older Hurlcon heaters may have only 3 buttons on the label, but has a cutout on the back for the 4th Pool/Spa button. You will need to replace the Sticker/Label on these. If you don't have a cut-out, replace the facia and overlay.

Older Thermostats:
Older analogue and digital thermostats can be found here.

Replacement Labels / Decals:
We strongly recommend replacing the label / sticker / decal when replacing the PCB, as some of the older ones were not UV Resistant. The "sticky" part also perishes when exposed to sun & weather over long periods of time.
