Hot Start Control
Anti Cold Draft Control
When Heating operation starts, Indoor Fan will not start until the indoor heat exchanger reaches 30°C as diagram shown.
Hot Start is completed when indoor heat exchanger rises to 39°C or over 4 minutes.
• This operation is to prevent the Cold Draft during Heating mode operation.
• The operation will start when compressor OFF (Thermo OFF) during Heating operation.
• For the first 30 sec. from compressor OFF (Thermo OFF), Indoor fan speed will operate accordingly to the Indoor heat
exchanger temperature as shown below:
• After 30 sec. from compressor OFF (thermo OFF), Indoor fan will run at SSLo speed only.
• Anti Cold Draft Control will stop when:
− Intake temperature < set temperature. (Time Delay Safety Control 4 minutes waiting is valid)
− After 30 minutes time saved control.
(see page 24).
