| Thank
you for choosing WeatherCraft airconditioner
control unit. The Weather Craft STR is a high
quality control unit for air conditioner based
on the microprocessor technology. The high-speed
microprocessor measures the temperature of
the room and controls the hardware components
to maintain the room temperature at +/- 1
C of the set temperature. Besides this, the
IR remote control, built in timer function,
sleep mode and dry mode makes the A/c easy
to use and maintain. |
|
FEATURES |
Cool / Sleep / Dry / Fan four operation modes
High / Med / Low three kind of indoor speed
Sleep function· Dry mode to reduce the room
moisture at minimum
cost
Three minutes time delay to protect the compressor
Temperature precision +/- 2c
Dual 7 segment LED to display the room temp
and the set temp
24 hours on and off timer
Temperature setting +10c to +31 c |
 |

PWR
OPERATION
Press PWR to turn the A/C on.
The A/c will start operating at the factory
preset, if the main supply is turned on for
the first time.
Factory preset: Cool mode, Hi Fan Speed, Normal
Timer, Swing on. Set temp at 22c.
Press PWS to turn the A/c off.
POWER OFF MEMORY RETENTION: If PWS is pressed
again without turning the main supply off;
the A/c will operate
with the previous setup. |

SET
OPERATION
The temp is measured at the A/c grill. There
will be a temp difference the room floor and
the ceiling. So set
up temp depends on how high the A/c is installed,

corresponding indicators will blink if the
compressor is not on and
will stop blinking if the compressor is on.
|
| |
COOL
MODE
The control unit cools the room air to the
set temperature.
If the room temperature is greater then set
temp +1c, the compressor is turned on.
When the room temp reaches set temp -1c the
compressor is turned off.
To protect the system, the minimum running
rime of the compressor is 3 minutes. |
| |
SLEEP
MODE
The device is useful to maintain an appropriate
temperature during the night so that excessive
energy is not used.
If you need 24c temp after 2 hours, follow
the following steps.
Set up the room temp at 22c · Select sleep
mode.
The A/c starts counting time down · After
one hour the set up temp will be 23c
After another hour set up temp will be 24c
and it will remain the same for the whole
night. |
| |
DRY
MODE
This mode is selected then the outside temp
is comfortable but the humidity is high.
When this mode is on, keep your ceiling fan
on.
The A/c fan speed is pushed to low.

and 3 minutes on.
If you press the SET, the display will show
DH.
It means the A/c is in
dry mode so you cannot program the set up
temp. |
| |

| SHOCKING
TRUTHS ABOUT ELECTRICITY |
| |
ELECTRICITY
Electricity has become so common, that we
sometimes, take it for granted. Carelessness
even while pulling out a plug from a socket
could result in a nasty shock. It is necessary
for us to take precautions against electrical
hazards, because it could result in grievous
injuries or damage to property or both. |
| |
INJURIES
SHOCKS
The flow of electrical current through the
body causes a shock. When it is an alternating
current, i.e. the normal
electricity we receive at home, the dangers
are enhanced because it causes an involuntary
grip, which prolongs
the period of contact. More the period of
contact, more the damage.
An electrical current flows through the nerves
and muscles and disturbs their normal functioning.
Passage of current
through the heart, stops blood supply to the
brain, resulting in loss of consciousness
and termination of breathing.
When a person standing at a height receives
an electrical shock, it is most likely that
he will fall.
Personal sensitivity to electrical shock varies
from person to person. |
| |
BURNS
Whenever an electrical flash appears, and
if a part of the body comes within flashing
distance, burns can
be caused.
Burns may be caused by short circuits as well,
because a short circuit could create an electrical
fire.
Excessive heat results in burns, which damage
the skin and cause injury to cells. |
| |
| PRECAUTIONS
·
Allow only a qualified engineer to attend
to your electrical repairs
Think that a circuit is "live" and ensure
that it is "dead" only after you test it.
Make sure your extension cords are free
from cuts, improper insulation, kinks or
joints.
Ensure pins of your plugs are tight and
not loose.
Make sure that you have easy access to switch
off the supply source quickly, in case of
an emergency.
Use appliances with 3 pin plugs or 3 pin
MCB and connect to 3 pin sockets.
Service your electrical equipment at frequent
intervals through a competent electrician.
All domestic houses having Air conditioner
must have ELCB. (Earth Leakage Circuit Breaker)
& MCB on all
Air conditioners.
Switch off electrical appliances when not
in use.
Be sharp in identifying and reporting electrical
hazards immediately.
In case of short circuit or a fire, switch
off the mains instantly.
Memorize first aid procedures. You never
know when you may need them. |
| |
| NEVER |
Never insert naked wires into sockets. Avoid
making temporary connections.
Never work on wet electrical equipment.
Never user trial and error methods with electrical
circuits
Never operate a switch without knowing the
consequences.
Never overload an electrical point. In case
of replacing gadgets, replace with the same
rating
Never attempt to extinguish an electrical
fire with water. Use dry sand of DCP extinguishers.
Never crowd your articles around the mains
or switches. Otherwise in case of emergency
it may not be easily
accessible.
Never take short cuts. Follow the safety procedures
meticulously.
Never use broken plugs. · Never operate electrical
switches and gadgets with wet hands. |
| |
| ACCIDENTS
RELIEF |
If someone has been injured by an electrical
shock, give the victim artificial respiration
and call for a doctor
immediately. The victim needs fresh air, so
ensure that people do not crowd. If the victim
has suffered burns,
hold the affected part under water.
Incase of an accident, emergency action comprising
simple first aid measures can minimize injury
and even save lives.
