5.9 Offset function
5.9.1
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.

Explanation
MODE1
Control the temperature so that the discharge temperature of
the circulating fluid is circulating fluid set tempe 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 tempe offset temperature.
MODE3
Control the temperature so that the discharge temperature
of the circulating fluid is circulating fluid set tempe
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.
