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 microcomputer-controlled defrosting system
operates. At the same time, the fan on the indoor unit stops (or runs at
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) with each wireless remote controller having the ADDRESS switch set
differently.
Should the power fail while the unit is running
•
If the power supply for this unit is temporarily interrupted the unit will
automatically resume operation (once the power is restored) with the
same settings that were in effect before the power was interrupted.
•
Be sure to place the wireless remote controller where it can operate the
air conditioner correctly.
