7-4. Indoor unit fan motor over temperature protection
When satisfy the following conditions, the protection works.
• After the 90 seconds from the fan operation, detect less than 200 rpm for 10 seconds.
• IPM trip protection works.
• Current overload protection works.
When detecting the above condtion, recheck the condition after 6 minutes. When count the twice,
the protection works.
• Protection contents
Reduce the static pressure 20 Pa. When it does not dissolve even the minimum static pressure
condition, work the following operation.
– Fan motor error displayed when less than 200 rpm for 10 seconds is detected after the 90 sec-
onds from the fan operation.
– Fan stop 40 seconds when IPM trip protection works.
– Fan stop 50 seconds when corrent overload protection works.
