Function - Sharp CV-10CTX-W Service Manual

[2] FUNCTION

The temperature in this manual is expressed by Centigrade.If Fahrenheit is used, the switchover between them is
Tf=TcX1.8+32.
1.Temperature Parameters
◆ Indoor preset temperature (Tpreset)
◆ Indoor ambient temperature (Tamb.)
2.Basic Functions
Once the compressor is energized, there should be a minimum
interval of 3 minutes between two start-ups. Once the compressor
operates, the unitwill not stop within 6 minutes due to temperature
change.
1)Cool Mode
(a) When Tamb.≥Tpreset+1°C(2°F), the unit starts cooling
operation. In this case, the compressor and motor operate and the
fanoperates at set speed.
(b) When Tamb.≤Tpreset-1°C(2°F), the compressor and the motor
stop while the fan runs at set speed.
(c) When Tpreset-1°C(2°F)<Tamb.<Tpreset+1°C(2°F), the unit
willmaintain its current running status. In cooling mode, temperature
setting range is 16~30°C(61~86°F).
2)Dry Mode
In this mode, the set temperature and ambient temperature will not
be displayed. Fan will operate at low speed while compressor , fan
and motor continuously operate.
3)Fan Mode
In fan mode, set temperature and ambient temperature will not
be displayed. Fan will operate at set speedwhile compressor and
motor stop operating.In this mode, temperature setting range is
16~30°C(61~86°F).
4)AUTO Mode
In AUTO mode, Tpreset in standard cooling is 25°C(77°F) while in
standard heating is 20°C(68°F).
When Tamb.26°C>(79°F), the unit enters auto cooling mode;When
Tamb.20°C<(68°F), the unit enters auto fan mode;
When 20°C(68°F)≤Tamb.≤23°C(73°F) if the unit is in fan mode, it
will keep its status; If not, it will enter auto dry mode;
When 26°C(79°F)≥Tamb.≥24°C(74°F), the unit enters auto dry
mode;
When 26°C(79°F)≥Tamb.≥20°C(74°F), If the unit is energized for
the first time, it will enter dry mode.
3.Basic Functions
1)Buzzer
Upon energization or availably operating the unit or remote
controller, the buzzer will give out a beep.
2)Sleep Function
(a) After setting the sleep function in cooling mode, Tpreset will
increase1°C(2°F) in 1 hour later and 2°C(4°F) to tally in 2 hours
later.After that, the set temperature will not increase any more and
the upper limit of set temperature after increase is 30°C(86°F).
(b)There is no sleep function in Fan or Dry mode.
(c)After setting sleep function, it will be cancelled by switching
operation mode.
(d)The set temperature displayed on remote controller will not
change with the decrease or increaseof the set temperature in this
mode.
3)Auto Fan
(a)fan speed in cooling mode:
Tamb.≥Tpreset + 2°C(4°F),
Tpreset<Tamb.<Tpreset +2°C(4°F),
Tamb.≤Tpreset,
(b) There is 210s' delay for switch of Auto Fan mode.
High speed;
Medium speed;
Low speed;
4)Timer function
General Timer
Timer ON can be set at unit OFF. If selected ON time is reached,
the unit will start to operate according to previous setting status.
Time setting range is 0.5-24hr in 30-minute increments.Timer OFF
can be set at unit ON. If selected OFF time is reached, the unit
will stop operation. Time setting range is 0.5-24hr in30-minute
increments.
Clock Timer
Timer ON
If timer ON is set during operation of the unit,the unit will continue
to operate. If timer ON is set at unit OFF, upon ON time reaches the
unit will start to operate according to previous setting status.
Timer OFF
If timer OFF is set at unit OFF, the system will keep stand by status.
If timer OFF is set at unit ON, upon OFF time reaches the unit will
stop operation.
5)Memory Function
If the unit is de-energized, it will operate at the previous mode after
it is energizedagain. If the unit operates before de-energization,the
compressor will operate in 3 min later after the unit is energized
again.
6)Indicator Lamp and "Dual 8" Nixie Tube
(a)When the unit operates at cooling mode, the cooling indicator
lamp is on and "dual 8"nixie tube displays set temperature.
(b)When the unit operates at fan mode, the fan indicator lamp is on
and"dual 8"nixie tube will not display anything.
(c)When the unit operates at dry mode, the dry indicator lamp is on
and "dual 8"nixie tube will not display anything.
7)Button
(a) ON/OFF :control ON/OFF of the unit
(b) Mode: The setting of mode is circulated as the cooling mode、
Dry mode、Fan mode.
(c)/: Press "+" to increase the set temperature while press "-" to
decrease the set temperature when the unit operates.The set
temperature will increase or decrease 1°C or 1°F for each press.
The set temperature can't be decreased if it reaches 16°C or 61°F
while it can't be increased when it reaches 30°C or 86°F. In that
case, Auto, Dry or Fan mode will be invalid.
(d) Fan: Fan speed setting circulated as following: low-medium-
high-auto-low.
8)Light Control
If light is turned on by remote control, the indicator lamp and "dual 8"
nixie tube will display the current status. If it is turned off, all lights
will be turned off. If the button on front panel or remote controller
is pressed when the light is turned off, the indicator lamp and "dual
8"nixie tube will display the current status for 5s and then the light
will be turned off. The display of malfunction is not affected by
remote light control.
4.Protection Function
1)Freeze Prevention Protection
When the freeze prevention protection is detected, the compressor
will stop and the fan will operate at set speed. Once such protection
is removed, the previous status will be resumed in 3 minutes later.
2)Overflow Prevention Protection
When detecting that the water is full for continuous 3 seconds,
overflow prevention protection will occur, malfunction code H8 will
be displayed.
