1.1.12 Mold Proof Air Filter
For FTK(X)25/35 J,
FTK(X)50/60 H
Series The filter net is treated with mold resisting agent TBZ (harmless, colorless, and odorless). Due
to this treatment, the amount of mold growth is much smaller than that of normal filters.
1.1.13 Pre-Heat Operation (Heat Pump Only)
For FTK(X)25/35
J,
FTK(X)50/60 H
Series 1. When the equipment has been stopped, the compressor is warmed up by passing a small
single-phasing current through the compressor motor so that the start up is speeded up.
2. The power consumption during warming up is about 15 to 35W.
3. This function operates only when the outside temperature is low (less than about 10ºC) so
that power saving is achieved.
1.1.14 Hot Start Function (Heat Pump Only)
In order to prevent the cold air blast that normally comes when heating is started, the
temperature of the heat exchanger of the indoor unit is detected, and either the air flow is
stopped or is made very weak thereby carrying out comfortable heating of the room.
*The cold air blast is also prevented using a similar control when the defrosting operation is
started or when the thermostat gets turned ON.
During defrosting or when the thermostat is on in heating mode, the indoor heat exchanger
temperature
≥
29°C to fan starts to avoid cold draft.
1.1.15 Program Dry Function
Program dry function removes humidity while preventing the room temperature from lowering.
Since the microcomputer controls both the temperature and air flow volume, the temperature
adjustment and fan adjustment buttons are inoperable in this mode.
In the Case of
Inverter Units The microcomputer automatically sets the temperature and fan settings. The difference
between the room temperature at startup and the temperature set by the microcomputer is
divided into two zones. Then, the unit operates in the dry mode with an appropriate capacity for
each zone to maintain the temperature and humidity at a comfortable level.
