I'm having a problem with an: rsey10kly1 outdoor. The ambient sensor is reading 35c in an ambient of 5c, it's not high enough to trigger a fault yet unit won't heat as it thinks the ambient is too high.

I've swapped the probe with a good one, no joy, could there be anything else "dragging" this value out or is it a case of a board replacement?

PS
i wish it was 35c.............
