Compulsory defrosting should be done as follows.
1Change the DIP SW1-1 on the outdoor controller board from OFF to ON.
2Compulsory defrosting will start by the above operation 1 if these conditions written below are satisfied.
• Heat mode setting
• 10 minutes have passed since compressor started operating or previous compulsory defrosting finished.
• Pipe temperature is less than or equal to 8:.
3Compulsory defrosting will finish if certain conditions are satisfied.
wCompulsory defrosting can be done if above conditions are satisfied when DIP SW1-1 is changed from OFF to ON.
After DIP SW1-1 is changed from OFF to ON, there is no problem if DIP SW1-1 is left ON or changed to OFF again. This
depends on the service conditions.
9-2. OUTDOOR UNIT
9-2-1. Function of switches
w 1. Do not use only SW5-1 to fix the frequency setting. The compressor operating frequency can be fixed to the desired Hz
by the combination of the SW5-1 setting and optional parts “A Control Service Tool (PAC-SK52ST)” setting.
w 2. “Power failure automatic recovery” can be set by either remote controller or this DIP SW. If one of them is set to ON,
“Auto recovery” activates. Please set “Auto recovery” basically by remote controller because all units don’t have DIP
SW. Please refer to mode 01 in the table on page 10. FUNCTION SETTING.
w 3. SW7-1,2 are used to switch the setting of “Demand function”. However, local electrical construction will be
required to make use of this mode. Therefore SW7-1, 2 are effective only when the mode is available for the model.
w 4. Do not use SW7 normally, or troubles may be caused by the units’ installed condition and used condition.
w 5. RP10YHA(-A) is always ON.
