Freezer Digital Indicator - what's the point?

Why should green mean cold? How is that culture independent? (You see the same convention with water taps sometimes.)

Not helpful if it's inaccurate.

I can see that a built-in thermometer could be useful provided it's reasonably accurate.

My toes go blue, not Green

So would I.

But I'd rather have a dial 1-6 than a definite temperature that is no more than a misleading guide.

And as I said at the beginning that result in soft frozen fish, so roughly frozen as a result.

Keep them too cold too long and they might go green.

That comment was about using temperatures, not arbitrary numbers, stupid.

Still more helpful than a color or a random number.

I wouldn't. Definite temperatures are much better because you can use that scale to set it to what you require and then use a thermometer to see how close the scale is to reality.

They actually go black if you do that.

How widespread is the use of colours to denote hot and cold (whether for hot/cold taps or for hotter/colder turn-direction arrows on a rotary control)? And how widespread is the choice of colours used? I know that UK taps use either green or blue for the cold tap and red for the hot tap - if colours are used at all. But is there an international convention for colours, if they are used?

A lot of modern mixer taps, especially the sort where you rotate a lever to vary temperature and rock it fore/aft to vary the flow rate, seem to have no labelling of any sort, whether colours, words or icons. You just have to try it and see, and hope that the water runs hot quickly so you don't wait for ages with the lever rotated in one arbitrary direction before deciding "it's not running hot yet, so I'll rotate it fully in the opposite direction".

I'm one of those odd sort of people who prefers a word in a foreign language to an icon which I cannot decipher. My brain can evidently read a foreign word and remember it in case I encounter it again, better than I can recognise an icon and compare it against a vaguely similar but not identical icon seen in the future.

Traffic signs are easy because they are a small finite set and every "bend" sign or every "gradient" sign is drawn the same as every other one. The problem comes with icons which individual manufactures invent for their own equipment, where you have to get past the "WTF is this a picture of?" stage before you can pass the much easier second stage of "what is the significance of a icon that shows a floppy disc?"

I remember when I was driving my dad's Ford Sierra many years ago. This had a row of warning lights on a panel in the centre of the dashboard. The symbols were invisible unless a light was lit, so you never saw the symbols so you never thought "I wonder what that one might be for?". Suddenly a light started flashing. I had not got the foggiest what the icon depicted, so I couldn't start to think "what is it telling me". But the light was flashing: that's something that I evidently needed to be aware of and to act upon immediately. When I stopped and found the manual, it took ages to find the section that showed the warning lights, and then even more time to find which one of the icons in the manual looked most similar (but not identical) to the one on the dashboard. Eventually I came to the conclusion that the closest match was to the one telling me the windscreen washer bottle was empty: useful to know, probably useful to fill the bottle sooner rather than later in case I needed to wash the screen, but not something that needed a flashing "this is very important" high-priority interrupt. ;-)

But it is hard to see that that is true of hot and cold water.

Thats a bit weird but I spose your brain doesnt work as well with pictures as words.

Yeah a real problem with smartphone apps and you can't even hover to see the description text in your own language.

Even worse when say you need a particular function and are trying to decide which one is the one you need with some of them.

I had to laugh the other day, I know a guey who was sold a Bluetooth fridge and freezer thermometer pair. The only problem was, that it did not work inside his oldish metal fridge Freezer, not enough signal could get out. Obviously designed by the same person who invented the Helicopter ejector seat.

It also is worse since a blind user could not see the lcd, but a tactile dot or few would go a long way to helping this. They do do fridges with mobile apps now so you can join them to your network. The Samsung Smart things app is what you need. Brian

There's nothing wrong with helicopter ejector seats (a few helicopters do have them) - you just need a small time delay on activation, to allow explosive bolts to shed the rotor blades before the normal ejection sequence.

wasn't it the B47 where the ejector seats went down?

But do you know if the fridge and freezer have their own separate compressor ?. If so, this would be either unusual or a high-end model. Separate settings for fridge and freezer does not mean that there are 2 independent cooling systems.

The user manual will state the minimum temperature of the room where it is located. My 15-YO entry level Liebherr FF, with an old fashioned electro-mechanical wax thermostat has a switch next to the thermostat setting that must be toggled on, if the appliance is in a room where the temp is below 18C. This switch just leaves the internal light on all the time, but powered via a resistor inside the thermostat housing, so that the bulb is only dimly lit. This warms up the air around the 'stat making it think that the compressor needs activating, so keeping the freezer at -18C.

Your Samsung FF might have a single compressor but some logic that forces the compressor to run if the freezer temp is above -18C even if the fridge is at 4C.

The V bombers only had ejection seats for the pilot and co-pilot. The rest of the crew had to slide down out of a flap under the fuselage.

Apropos on 1950s bombers there's a couple of B52s, possibly armed with nuclear cruise missiles, hanging around over W. Europe...over Denmark this morning. Just to remind that nice Mr Putin not to lose his temper...

What if there is a single letter abbreviation for the word? Like the French C and F, which might be interpreted as "Cold" and "Freezing".

Does flashing always mean more urgent? For low fuel warnings they had flashing for "a bit low" and solid for "really low, get more fuel now". This is because there was a contact on the float in the tank, so as it sloshed about the light flashed, and when it was really low the contact was always made.

I had an ink jet printer which worked in a similar way wrt the ink levels.
