Explanation of optional functions
2Way solenoid valve
 When installing multiple number of outdoor units to a common water pipe, 2way valve will cut the cooling water supply
to an outdoor unit that is not operating, so it will increase the overall eciency of the system. 2Way solenoid valve will
operate automatically depending on the operation status of the indoor and outdoor units. (Outputs contact signal)
 You may select either internal or external power cable connection for the 2way solenoid valve.

2Way solenoid valve
 Connect the 2way solenoid valve cable to the 2way valve terminal regardless of the polarity.
(However, Use external power if the load of solenoid valve is maximum 250 V and current over 0.2 A.)
Flow control
 After setting the outdoor unit option switch, you may connect variable ow control valve that is controlled at 0 ~ 10 V of
input signal.
 If the power of variable ow control valve is AC 220-240V, you may use the internal power of the outdoor unit.
 When applying the DC 24 V ow control valve, use Transformer kit MVR-TK024 (optional).
 Use the external power if the load of variable solenoid valve is maximum 250 V and current over 0.2 A.)
 Output range of the variable ow control valve is dierent depending on the setting of the outdoor unit option switch
(Refer to 'Setting key operation and checking the view mode with tact switch' on page 76)
