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.
Control Off mode:
The LCD is fully turned off. The heater/ cooler is
