OVERVIEW & INTRODUCTION
Heat Mode mode.
* temperature control range: 60---86°F
* temperature dierence: ±2°F
Control feature: the temperature compensation is
automatically added and the system will send the heating
signals to the outdoor system.
If Tr≤Ts, the outdoor compressor is turned on, the indoor
fan will be at the cold air proof mode.
If Tr>Ts+, the outdoor system is turned o, the indoor fan
will be at the heat residue sending mode.
If Tr<Ts+, the outdoor system will be turned on again, the
indoor fan will be in the cold air proof mode.
Indoor fan control
Manual Control: You can choose high, medium, low and
automatic speed control. Automatic:
When Tr<Ts, high speed.
When Ts≤Tr≤Ts+4°F, medium speed.
When Tr> Ts+4°F, low speed.
When the airow speed has no delay from the high to low
switching, the speed should be delayed for 3 minutes (remain
at high speed for 3 minutes.) before the next switch.
*Louver location control: the location for the louver can be set
according to your needs.
Cold air-proof operation
1. The indoor operation within 4 minutes after the start
up is as the following diagram, the air speed can be raised only
after the speed has reached a certain level.
2. 4 minutes after the start up of the indoor fan, the
light airow and the low airow will be turned to the set speed
airow.
3. In the cold air proof operation, the fan won’t stop
after the start up.
4. During the cold air proof operation, the indoor system
will continuously send ‘indoor high speed’ signals to the
outdoor system.
* Residue heat sending. The indoor fan will send the
residue heat at a low speed for 12 seconds.
If other conditions are satised, when the compressor stops,
the indoor system will operate at a light speed. The indoor
fan will stop when the coil temperature is below the heat start
temp 4’.
* Defrosting. When the system receives the defrosting
signal from outdoors, the indoor fan will stop and the indoor
temperature display won’t change. At thistime, any indoor coil
malfunctions will be neglected. When the outdoor defrosting
nishes, the coil malfunction will still be neglected until the
compressor has been started up for 30 seconds. The indoor
temperature display will not change and the system operates
at the cold air proof mode.
* Automatic heating temperature compensation:
when the system enters the heating mode, the temperature
compensation (4) will be added. When the status is switched
o, the compensation will be erased.
Timing
You can set 24 hours on/o timing. After setting, the timing
indicator will be displayed. Also, the light will turn o after the
timing is set. The followings are several timing methods:
1. System ON timing: The timing indicator will be
displayed and the indoor system is under the waiting mode.
The light will be turned o when the timing is nished and the
rest of the system will operate under a normal condition. The
timing starts since the last reception of the timing signal.
2. System /OFF timing: When the system is turned on,
the timing indicator will be displayed; the rest of the system
will operate under normal conditions. When the set time
expires, the indicator display will turn o and the system will
turn o. If you have set the dormant functions, the order
of your settings will be operated according to the timing
settings.
3 . System ON/OFF timing: The settings will be
completed according to the settings.
