• Use the cursor to select "Run" or "Stop" of "MC Operation".
Also, select either "Enable" or "Disable" for "System A
operation" and "System B operation". If "Disable" is selected,
the corresponding system will not operate even if "MC
operation" is set to "Run".
• If "Run" is applied, the "Run" lamp lights up. The pump starts
up first, followed by restart of the compressor and other
devices. If "Stop" is applied, the compressor and other devices
stop, and the "Run" lamp turns off. (Subsequently, the pump
continues running for at least 15 seconds.)
• When the operation setting is "Unit", operation enable/disable
for each MC operation system can be operated. The functions
that can be operated will change depending on the settings for

during "External" or "Remote" operation, the operation is
automatically switched to local operation and operation is
