Temperature Span Selection
Span is the temperature difference between the
turn
on temperature and turn off temperature. For
example,
in heating system, if you set temperature
to 20°C
and span to 1°C, the heater will operate
when the
room temperature drops to 19.5°C and
turns off when
the temperature rises to 20.5°C. Set
the DIP switch
(position 1 & 2) according to your
selection of temperature
span as the following
diagram.
