5.8 Offset function 
5.8.1 Offset function 
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
o
C, but the fluid 
temperature in the customer’s device is 29
o
C because of heat radiation 
during sending of the fluid.

MODE  Explanation 
MODE1 
Control the temperature so that the discharge temperature of 
the circulating fluid is circulating fluid set temperature + offset 
temperature. Circulating fluid temperature indicates the 
circulating fluid discharge temperature. 
MODE2 
Control the temperature so that the discharge temperature 
of the circulating fluid is circulating fluid set temperature. 
Circulating fluid temperature indicates the circulating fluid 
discharge temperature + offset temperature. 
MODE3 
Control the temperature so that the discharge temperature 
of the circulating fluid is circulating fluid set temperature + 
offset temperature. Circulating fluid temperature indicates 
the circulating fluid discharge temperature - offset 
temperature. 
OFF 
Control the temperature so that the discharge temperature of 
the circulating fluid is circulating fluid temperature set value.
