Power cuts
One of this thermostat’s special fea-
tures is that it does not need a bat-
tery to conserve the selected set
points if a power cut occurs. Its
memory is not affected by power
cuts, no matter how long they last.
When the current returns, the ther-
mostat will continue to operate as if
the power had never been discon-
nected.
Temperature precision
The thermostat will measure the
temperature exactly once it has been
installed and powered up for at least
one hour.
