HEC 4-5
4-6 Reading temperature average data
Note) For this product, the average temperature data, Tm, indicates the temperature of the external
sensor. Refer to “4-4 Reading external sensor” for the format.
4-7 Offset setting (without writing EEPROM)
Set offset of each Thermo-con from host. In this command, offset data loses effect with furning power to
