4.1 Temperature setting (without writing FRAM)
The host computer sets temperature of each Thermo-con. In this command, temperature setting data
is not written in FRAM. This data is invalidated by turning off power.
The setting range is from 10.0 to 60.0 deg.C. As 0.1 deg.C is the minimum unit, the number in the
hundredths place (10
-2
) should always be 0 (=30H). (When the value at every 0.01deg.C is input, it is
rounded off.)
