Information on Disposal of Old Electrical
and Electronic Equipment (applicable for EU
countries that have adopted separate waste
collection systems)
Products with the symbol (crossed-out wheeled
bin) cannot be disposed as household waste.
Old electrical and electronic equipment should
be recycled at a facility capable of handling
these items and their waste by products.
Contact your local author ity for details in locating a
recycle facility nearest to you.
Proper recycling and waste disposal will help conserve
resources whilst preventing detrimental effects on our
health and the environment.

Resetting the Microcomputer
The microcomputer may malfunction (unit cannot be
operated, or shows an erroneous display) if the power
cord is unplugged while the power is ON, or due to
some other external factor. If this happens, execute
the following procedure to reset the microcomputer and
return the unit to its normal operating condition.
While holding down [
power cord and plug it back in.
• Please note that resetting the microcomputer will clear
the contents of the memory and return the unit to the
state it was in when it left the factory.
] key on the unit, unplug the

CIRCUIT DESCRIPTION
Fan Motor Control
●
Fan control signal from the microprocessor IC601 (X08)
is supplied to the base of the transistor Q502 if changes
thermal level. Normally the base voltage of Q502 is low and
Q502 is not turn-on. The base of Q503 is minus voltage
so Q503 is turn-on. Zener diodes D512 and 513 are short
circuitry if Q503 is on. The collector’s voltage of Q503 will be
the same as zener diode D524, -10volts. This voltage leads
fan motor to turn with low speed.

When thermal sensor works, the microprocessor will send
the signal to Q502 and Q502 is turn-on. The base of Q503
becomes high level and it is not turn-on. Zener diodes D512
and 513 work. The base of Q504 is high level, -26volts. Fan
motor will turn with high speed.
