7-5. Overload Prevention (Heating)

●

This function prevents overheating of the indoor heat exchange coil.

For

(FCR518HL - AWR518HL) (FCR522HL - AWR522HL)

●

When the temperature of the indoor heat exchange coil rises above 59°C, and if the indoor fan is L (low speed),

then the fan speed changes from L (low speed) to M (medium speed).

●

When the temperature of the indoor heat exchange coil rises above 61°C, the outdoor fan stops.
