INSTALLER SETTING

ENGLISH

- Stop temp. : cut-off temp. Stop temp. is valid when FCU is set as ‘Use’.

- FCU : determines if FCU is installed or not.

- Example : If Stop temp. is set as ‘10’ and FCU is ’Use’ and actually FCU is NOT installed in the

water loop, the unit stop operation in cooling mode when the leaving water temperature is
below 10 °C.

- Example : If Stop temp. is set as ‘10’ and FCU is ’Not use’ and actually FCU is installed in the

water loop, the Stop temp. is not used and the unit do NOT stop operation in cooling mode
when the leaving water temperature is below 10 °C.

CAUTION

FCU Installation

• If FCU is used, related 2way valve should be installed and connected to the unit PCB.

• If FCU is set as ‘Not use’ but FCU or 2way valve is NOT installed, the unit can do abnormal

operation.
