The thermostat should be mounted on an inner wall
1.5m above the floor in position where it is readily
affected by changes of the general room temperature
with freely circulating air. Prevent direct exposure to
sunlight; dripping or splashing area. Do not place this
unit at a location where air circulation is low, or where
it has great temperature changes (e.g. near door). Do
not place the thermostat near heat/cool generating
sources.
