1) The judgment of selecting COOL/HEAT is carried out as shown
below. When +1.5 exceeds against Tsh 10 minutes and after
thermo. -OFF, heating operation (Thermo. OFF) exchanges to
cooling operation. Description in the parentheses shows an example
of cooling ON/OFF.
When –1.5 lowers against Tsc 10 minutes and after thermo. OFF,
cooling operation (Thermo. OFF) exchanges to heating operation.
2) For the automatic capacity control after judgment of cooling/heating,
see Item 4.
3) For temperature correction of room temp. control in automatic
heating, see Item 3.
