Had a frustrating weekend with malfunctioning laptop and now must put together several units for install tomorrow, so haven’t looked.

Note that you only need pads at most for the DS18B20 as I imagine that the main use will be off board such as for your DHW.

LDR should be at left near the switches, etc, unless there’s an obvious spot on the right amongst all the other fun there.

Will need to consult with Bruno re LED positioning, but my instinct would be to put it as near the top centre of the board as possible so that it’s above the big red button and not obstructed by a big bad finger when finger is pressing button.  Is that possible?

We don’t have time to do a testing round for DS620 I suspect, so if at all possible TMP112 and DS620 should both be on.  Pads at most for the 18B20, but omit entirely if you really have to.

I have had no time to look at DS18B20 (or DS620) code yet, at all, sorry.

Maybe we can scrape a couple more PICAXE systems together for you in the very short term?
