heating performance deteriorates as outdoor temperature
decreases. (Due to heat pump system) Information
called “External device ready demand” is outputted from
terminal of electrical component box.
Use another heating appliance using this information, etc.

When changed to heating mode from stopped or cooling
operation mode, the unit does not work for about 3 minutes
for the sake of self-protection.
It may take about 5 to 10 minutes until the hot water is
delivered after starting the heating operation.
Oil Recovery
The water pump may run at a slow speed in order to
recover the oil in the system every 1 to 3 hours during
cooling or heating operation.
The unit will automatically resume the original operation
after about 5 to 10 minutes.
Remote Control Sensor
The temperature sensor in the Air-to-Water normally senses
the water temperature and can also sense the ambient
temperature of the remote controller. (room temperature)
For the details, consult the shop you purchased.
Should the power failure occurs while the
unit is running
When the unit automatically resumes operation after
temporary power failure, it uses the same settings before
the power was cut off.
NOTE
•
Group control function cannot be used for the Air-to-Water unit.
Be sure to confirm the individual remote controller connection is used for each Air-to-Water unit.
•
If your heating appliance is a radiator or floor heating, dew may be condensed on the appliance during defrosting
operation.
In that case, turn on the Air-to-Water in heating mode to prevent condensation.
