Sinclair SMF-C09AI, SMF-4E27AI, SMF-C12AI Dehumidifying mode, Heating mode, Defrost operation

7.2.2 Dehumidifying mode

1.The indoor fan is fixed in low speed

2. Low room temperature protection:

When room temperature decreases to below 10℃, indoor fan stop, when room temperature restores to over 12℃, indoor fan start.

3.At dehumidifying mode, the anti-freezing function of the indoor heat exchanger is the same as that of cooling mode.

7.2.3Heating mode

1. Indoor Fan actions at heating mode

Indoor Fan can be set at HIGH/MID/LOW/AUTO by using a remote controller, but Anti-cold wind function prevails.

7.2.4Defrost operation

1. Defrosting condition:

The temperature of outdoor heat exchanger remains consecutively lower than -2°cfor more than 40 minutes,

2. Ending condition of defrosting
