Why anyone would fool around with an old mechanical thermost which when
set for 62 gives a temp that varies from 66 to 70 or pay someone $30 to
come look at it is beyond me. For a little more you can buy a nice
accurate and programmable digital one that's very simple to install.


Because the T87F will be working long after the digital has fried itself.
Read the replies, and also, a digital that is supposed to be accurate to 1F,
will also have a dead band in it, and will also have to have the
anticipation set in many cases, or will perform worse than the T87...thats
why.
