OPERATING TIPS

Instructions related to heating are applicable to “HEAT PUMP MODELS” and “HEAT RECOVERY MODELS” only.

Cooling/heating priority (AIRSTAGETM

(VRF system Heat Pump model only))

•If another indoor unit in the same system is already operating in the cooling mode or dry mode, heating mode settings cannot be performed.

•If another indoor unit in the same system is already operating in the heating mode, cooling mode or dry mode settings cannot be performed.

Weekly timer

•Set different operating times for each day of the week.

•Set one or two operating spans (one or two ON times and one or two OFF times) per day.

•Set time to a resolution of 30 minutes.

•Use the “DAY OFF” setting to cancel operation for any day of the coming week (one-time cancellation).

Setting restriction

When is displayed there are functions for which settings cannot be made.

Energy save

•The energy conservation mode (ENERGY SAVE) raises the set temperature slightly in the cooling mode and lowers the set temperature in the heating mode to economically control the operation of the unit.

•If you press the ENERGY SAVE button while the unit is in the timer mode, the unit will go into the conservation mode when the unit starts with the timer.

•If you turn off the air conditioner while in the conservation mode, the mode will be shut off.

•The temperature set on the remote controller will not change if the energy save mode is used.

During cooling operation

When the ENERGY SAVE is pressed, the thermostat setting is automatically raised 2 °F every 60 minutes, until the thermostat is raised a total of 4 °F.

During heating operation

When the ENERGY SAVE is pressed, the thermostat setting is automatically lowered 2 °F every 30 minutes, until the thermostat is lowered a total of 8 °F.
