(6) Unit Protection Devices
3 min. Time Delay and 3 min. minimum operation time of compressor
– In normal operation, there is a time delay of three minutes (42HQG024/HWG605H : 5
minutes during heating mode) between compressor turning off and turning back on including initial power up.
– After compressor turns on, it will operate for 3 minutes independent of temperature condition.
Time Delay When changing the operation mode
– The unit operates immediately when changing mode from ON to OFF or from OFF to ON,
or indoor fan speed without the change of operation mode.
– The unit operates after 10-second time delay when changing operating mode.
– The unit operates after 3-second time delay when changing the set temp. without the
change of operation mode.
Frost Prevention of Indoor Unit.
– When the unit operates at low ambient temperature, frost may appear on the evaporator. When the indoor coil temperature is less than 0ºC for 10 minutes of continuous compressor operation from the start, microcomputer of the unit stops the compressor to protect the unit from the frost.
– The system performs this function only in COOL and DRY mode.
– The control procedure for indoor coil freeze protection.
1) The compressor and outdoor fan turn off.
2) Indoor fan operates according to user set speed.
3) The normal operation returns when the indoor coil temperature is greater than or equal
to 7ºC.
21
Indoor Coil High Temperature Protection
– The system performs this function only in HEAT mode.
– If the indoor coil temperature is greater than or equal to 57°C, the outdoor fan turns off and
does not turn on until the indoor coil temperature is less than or equal to 49°C.
– If the indoor coil temperature is greater than or equal to 62°C, the compressor turns off
until the indoor coil temperature is less than or equal to 42°C. The 3 min. time delay of
compressor is applied in this case.

Defrost
– In HEAT mode, outdoor coil may be frosted, which cause decrease of the unit performance. Therefore the microcomputer of the unit turns on or off the compressor to remove the frost.
– The defrost operation is performed as follows:
• Defrost initiation
1) On the basis of the demand condition considering the difference between indoor
coil temperature and indoor room temperature, controller decides defrost initiation
after satisfying two steps of preceding condition.
22
2) Preceding condition is
a) The first step is “the accumulated compressor on time is greater than 30
minutes.”
b) Second step is the one of below two
-The first condition ; If Real-Delta>Defrost-Delta for 60 continuous seconds and
the following conditions are all true then defrost initiates.
)The outdoor coil temperature<-2°C
)The compressor has been on continuously for 15 minutes.
OR
-The second condition ; If the outdoor coil temperature is less than -20°C and
the following conditions are all true then defrost initiates.
)The outdoor fan has been on continuously for 60 seconds.
)The compressor has been on continuously for 3 minutes.
• Defrost mode
The normal system operations are stopped and the system operates as follows.
a) The indoor fan, outdoor fan will be de-energized.
b) The compressor and R.V.S. will be energized.
• Defrost termination
The defrost cycle will terminate in one of the following cases.
a) The outdoor coil temperature is greater than or equal to +25°C.
b) 10 minutes after the start of defrost cycle.
• Auto refresh
During normal heating operation, if the unit becomes OFF mode condition, then
defrost mode will be performed at the OFF mode state of louver and display when
the second step of preceding conditions is satisfied regardless of first step.
Self-Diagnostic Function
The control will contain diagnostic test to verify the integrity of the system.
Once a malfunction is detected, the diagnostic control section will force the system mode
to OFF for 3 minutes. After the OFF delay, system mode is released and allowed to return
to its normal state. The system will be allowed to restart on its own. The diagnostic control
section will allow the system to fail 5 consecutive times before shutting down the system.

SHC is calculated with air entering on the indoor coil at 27°C db; if the indoor temperature is different, modify SHC as follows:
BELOW 27 C: SHC modify = SHC - (CF*L/S)/1000
ABOVE 27 C: SHC modify = SHC + (CF*L/S)/1000
It is possible to interpolate
