•
In heating operation, freezing of the outdoor unit’s coil increases. Heating capability decreases and the system goes into defrost operation.
•
The remote controller will read “
” until the hot air starts blowing.
•
It returns to the heating operation again after 6 to 8 minutes (10 at the longest).
•
During defrost operation, the fans of the unit continues driving (factory setting). The purpose of this is to maintain the amount of
ventilation and humidifying.
•
The change of air discharge grill’s location should be examined when the cold draft from air discharge grill is feared.
•
Though the fan can be stopped by the setting of remote controller. Do not stop the fan in the place where no ventilation by stopping
the fan may cause the influence of diffusion of air which it is dirty and moisture into another room, or the inflow from outside the
room. (outflow such as viruses from the sickroom, or smell leakage from the rest room, etc.)
7. Adjustment set temperature for the local situation:
When the RA is not taken directly from the room (e.g. not connecting the RA duct), the temperature of RA might be higher than
the set temperature of the standard indoor unit. In that case, be sure to adjust set temperatures of heating (humidification) and
cooling in accordance with the local situation.
•
Set temperature at factory setting: Heating (humidification) …21°C, Cooling (suction temperature at refrigerant heat exchanger) … 26°C
•
Configurable range of set temperature: Heating (humidification) …14 to 26°C, Cooling …18 to 33°C
The correlation is as follows:
Cooling set temperature = Heating (humidification) set tempe Temperature differential of cooling/heating thermo change-
over of thermo-off cooling/heating (ex. 26°C = 21°C + 5°C)
In addition, when the VRV system Heat Recovery series is connected, adjust the temperature of cool/heat changeover at the auto-
matic operation in accordance with the local situation.
•
Changeover temperature at factory setting: Heating (humidification) …15°C, Cooling (outdoor temperature) … 25°C
•
Configurable range of changeover temperature: Heating (humidification) …10 to 18°C, Cooling …19 to 30°C
The correlation is as follows:
Changeover temperature for cooling mode = Changeover temperature for heating mode + Temperature differential of cooling/heat-
ing mode changeover (ex. 25°C = 15°C + 10°C)
