 This function controls the offset temperature to the circulating fluid
discharge temperature
 Control range of the circulating fluid temperature is 5.0
 When the circulating fluid temperature is set to 5.0

Electric conductivity control method

When option DM is selected, circulating fluid flows to the DI filter via a
solenoid valve to control electric conductivity.
This solenoid valve can be set to always OPEN,or always CLOSED.
The factory setting is "CTRL: Electric conductivity control".
By pressing the [▲], [▼] key, always OPEN, or always CLOSED
can be set.
