5.9.1 Offset function
5.9 Offset function
5-22
This function controls the circulating fluid discharge temperature with offset.
Temperature offset may occur between the thermo-chiller and the
customer's device depending on the installation environment. To correct the
temperature offset, three types of offset functions are available (MODE1 to
3). The default setting of this function is "OFF".
【When communication is used】
The circulating fluid temperature sent by serial communication is the
circulating fluid temperature which is displayed on the thermo-chiller (the
circulating fluid temperature after offset).
●Example of temperature offset
The discharge temperature of the circulating fluid is 30
temperature in the customer's device is 29
during sending of the fluid.

temperature. Circulating fluid temperature indicates the
circulating fluid discharge temperature.
Control the temperature so that the discharge temperature
of the circulating fluid is circulating fluid set temperature.
MODE2
Circulating fluid temperature indicates the circulating fluid
discharge temperature + offset temperature.
Control the temperature so that the discharge temperature
of the circulating fluid is circulating fluid set temperature +
offset temperature. Circulating fluid temperature indicates
MODE3
the circulating fluid discharge temperature - offset
temperature.
Control the temperature so that the discharge temperature of
