We recently renovated our house: a major year-long job. One of the minor tweaks was a Honeywell programmable thermostat that has a touch screen that lights up when one presses it, to display an incredible array of data and possible inputs.
It is not intuitive, beyond the very basic + and - signs that allow a variation of the temperature (we have a heat pump so we can cool the house as well as heat it). I asked the HVAC guys for a manual and they told me to look online.
I did.
The manual is over 700 pages of dense print with some diagrams. It turns out that the manual covers every single model of residential control made by Honeywell. So to find out where the relevant bits are for my control I have to firstly find the model, which information is on the controller in extremely fine print with multiple alphanumerics. Then, without the aid of a good online index I have to find those portions of the manual that apply to my model and not to ones that look almost identical and that have model numbers that are very similar.
I usually wear bifocal contacts, which sacrifice a little precision for convenience. I literally can't read the very fine print on the panel, which, for reasons known only to somebody in Honeywell, is a pale green screen with relatively muted grey-black symbols, which are far more difficult to read than black on white, or other normal schemes. Maybe the pale green looked 'techno' to somebody aged 30 or less, with 20-20 eyesight.
The result is that I have (so I am told) a very powerful control interface that allows me to program my home climate, including (by use of an app I haven't downloaded) from my smartphone or ipad anywhere in the world, and all I know how to do is to turn the temperature up or down manually.
However, we had an issue with the heatpump and the tech showed my wife how to program automatic daily variations, so we have that dialled in now. Neither of us are sure that we could alter it again without the tech coming by.
How difficult would it have been to:
a) label the model number in a readily visible, readable manner
b) have a discrete manual for that model available on line, rather than having a single manual for dozens or scores of devices, with no good index
c) make the display legible by using a higher-contrast between the symbols and the background...even if space constraints prohibited a larger font.....for that matter, making the panel an extra inch wider and deeper wouldn't have cost an arm and a leg, given how much they charge for the system.
But this is a breeze compared to the tiny wall-mounted controller for our outside lights. I literally cannot read the font on the screen. Again, pale green background with pale grey symbols, but a tiny screen and even tinier font. Apparently we can program these as well, but neither of us can read the screen so even if we could find the manual online it wouldn't do us any good. So all we can do is manually turn them on and off.
I know: I am definitely becoming an irascible old git.
