Ashcroft would make sense if you had a digital probe. Im sure its reading would match my probe.
Theres science and then theres common sense. One ac works on room temp the other on ambient. I felt colder in gree and checked with my probe and it did show a lower temp. Htc also confirmed this but was not as accurate as digital probe.
Dont know if daraz have the newer manuals or old would have to buy from there to see.
The whole point is to tell you that when an ac maintains 26C it is actually lower than that. To test this you need a device that is highly sensitive to temp changes. This clock just doesnt have the capability to handle our area of interest i.e. to measure temp fluctuations while in an ac room.
Im going to stop here. Pictures prove everything.
Hope you have a nice day.
