NOTE
Special Remarks
•Because this appliance heats a room by utilizing the heat of the outside air (heat pump system), the heating efficiency will fall off when the outdoor temperature is very low. If sufficient heat cannot be obtained with this heat pump, use another heating appliance in conjunction with this unit.
•When the outdoor temperature is low, frost or ice may form on the outdoor heat exchanger coil, reducing the heating performance. When this happens, a
very low speed in some cases) and the 
(STANDBY) lamp lights on the indoor unit until defrosting is completed. Heating operation then restarts after several minutes. (This interval will vary slightly depending upon the outdoor temperature and the way in which frost forms.)
•For several minutes after the start of heating operation, the indoor fan will not start running (or it will run at very low speed in some cases) until the indoor heat exchanger coil has warmed up sufficiently. This is because a
cold draft prevention system is operating. During this period, the 
(STANDBY) lamp remains lit.
•
(STANDBY) lamp remains lit during defrosting or when the compressor has been turned off (or when the unit is running at very low speed) by the thermostat when the system is in the heating mode.
•Upon completion of defrosting and when the compressor is turned on
again, 
(STANDBY) lamp will light off automatically as the heating operation resumes.
When setting up two or three air conditioners in one room, you can control the air conditioners correctly by setting the ADDRESS switches of the Operation Controllers and the Wireless Remote Controllers.
You can control the air conditioners:
1) with one wireless remote controller changing the ADDRESS switch setting
of the wireless remote controller. | 2 | |
2) with each wireless remote controller having the ADDRESS switch set | ||
| ||
differently. |
