Heating/Cooling Selection
Inside the front cover, you will find the DIP switch. These three switches
are used to control the span and the Heating/Cooling system. The
DIP switch must be set before installing the batteries. Once the
batteries are installed, you cannot change from heating to
cooling (or from cooling to heating) unless the batteries are
removed or pressing the reset button. Set the DIP switch (position
1) according to your selection of Heating system or Cooling system
as the shown in following diagram.

Temperature Span Selection
Span is the temperature difference between the turn-on temperature
and turn-off temperature. For example, if you set the temperature to
20˚C and the span to +/-0.5˚C, the Heating system will operate when
the room temperature drops to 19.5˚C and turn off when the
temperature rises to 20.5˚C. Set the DIP switch (position 2 & 3)
according to your selection of temperature span as shown in the
following diagram.
