"HOT KEEP" is operated in the following cases.
When heating is started:
In order to prevent blowing out of cool wind, the indoor unit fan stopped according to the room temperature which heating
operation is started. Wait for approx. 2 to 3 minute, and the operation will be automatically changed to the ordinary heating
mode.
Defrosting operation (in the heating mode):
When it is liable to frost, the heating operation is stopped automatically for 5 to 12 minutes once per approx. one hour,
and defrosting is operated. After defrosting is completed, operation mode is automatically changed to ordinary heating
operation.
When the room thermostat is actuated:
When room temperature increases and room temperature controller actuates, the fan speed is automatically
changed to stop under low temperature condition of indoor heat exchanger. When room temperature
decreases, air conditioner automatically changes over to ordinary heating operation.
Heat pump type warming
With the heat pump type warming, the mechanism of heat pump that concentrate heat of outdoor air with the help of
refrigerant to warm the indoor space, is utilized.
Defrosting operation
When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat exchanger of outdoor unit
along with the drop of indoor temperature. Since the accumulated frost reduces the effect of warming, it is necessery to
automatically switch the operation to the defrosting mode. During the defrosting operation, heating operation is interrupted.
Atmospheric temperature and warming capacity
Warming capacity of heat pump type air conditioner decreases along with the drop of outdoor temperature.
When the warming capacity is not sufficient, it is recommended to use another heating implement.
Period of warm-up
Since the heat pump type air conditioner employs a method to circulate warm winds to warm
the entire space of a room, it takes time before the room temperature rises.
It is recommendable to start the operation a little earlier in a very cold morning.
