Temperature to trigger defrost operatio
▪ Purpose
Prevent excessive frost formation in a high-humidity condition.
(Apply setting when the product is being installed in a humid area such as near a river or lake.)
▪ Concept
Defrost operation is performed frequently if there is frost formation on heat exchangers in heating mode.
▪ Control specifications in detail
- Defrost operation is performed if the amount of frost that formed is smaller than the option setting when the heat
exchangers are checked for frost formation based on the difference between the outdoor temperature and heat
exchanger temperature (Cond out, Suction)
- See “Defrost control” for details on defrost operation specifications.
▪ Notes
- If this option is configured and the units are in a very humid location, heating performance may degrade due
to frequent defrost operation.
