4-2. Heating Standby
In heating mode, the indoor fan speed decreases to prevent cold air discharge from the indoor unit. During this
time, (heating standby) is displayed on the remote controller.
① This condition occurs in the following cases.
・ Thermostat OFF
・ Defrosting operation
・ Indoor heat exchanger liquid temperature (E1 or E2) < 28˚C just after heating operation started
The fan speed may sometimes increase when this condition continues for 6 minutes.
② The fan mode increases when the heat exchanger liquid temperature (E1 or E2) or discharge air
temperature increases.
The fan mode is selected based on E1 temperature and E2 temperature as shown in the below
figure. If the E1 temperature and E2 temperature are different, the higher temperature is used.
The function of “HH” is identical to the automatic fan speed mode.
