1. SMPS Part
QSMPS(Switching Mode Power Supply) Part Description
1. BRIDGE DIODE (BD71) provides full wave reification from AC input. Then smooth it with Electrolytic Condenser(C101).
Smooth voltage is similar to the results of AC input x1.414. (Ex: When AC220V is supplied, 220x1.414 = about DC310V)
2. The main power supply of ventilator is DC310V as it utilizes BLDC MOTOR.
3. PWMIC (IC01) switches smooth DC voltage, which is, in turn, induced to secondary side, so as to generate DC15V (C104) and
DC12V(C107).
4. The voltage of secondary side is decided by TURN numbers of TRANS winding. DC 15V is utilized only for CONTROL power source
of BLDC MOTOR while DC12V is used for power source of CO
2 sensor.
5. When BLDC MOTOR faulty takes place, DC 15V or DC 12V might not be generated.
6. SWITCHING DIODE of secondary side should not utilize usual rectification DIODE because SWITCHING speed of SMPS reaches
130kHz. High speed SWITCHING DIODE is required.
7. SMPS stops operation if SHORT occurs post voltage of DC12V because of FEEDBACK from DC12V.

2. Motor Load Part
Q
Motor Load(BLDC : BRUSHLESS MOTOR) Part Description
1. Smooth DC310V of electrolytic condenser (C101) is utilized for operation power source.
2. DC15V (C104) of secondary side of circulation is used for CONTROL voltage of MOTOR. BLDC CONTROL voltage must be lower
than MAX DC18V.
3. CONTROL voltage is distributed through No.5 PIN of CN73 and is lower than MAX DC7V. MOTOR RPM is determined by
DC0V~DC6V voltage.
4. No. 6 PIN of CN73 is the RPM FEEDBACK POINT, which delivers MOTOR rotation to MICOM. If DC15V continues to be found when
measuring DC15V and No.6 PIN, FAN MOTOR ERROR occurs because FEEDBACK is not conducted.
5. CONNECTOR of CN73 is dislocated when PCB power source is authorized, DC310V voltage may flow into CONTROL IC within BLDC
in a moment, damaging CONTROL IC of BLDC. It may cause SHORT of DC15V or DC310V.
6. If SHORT of DC15V or DC310V takes place, 2A FUSE (F702) opens and DC15V rectification DIODE may be damaged, which stops
operation of SMPS.

Communication (485 Communication) Part Description
1. Faulty Connection Prevention RELAY: When AC220-240V, 50Hz power is supplied to power source link, 12V voltage is provided
to RELAY, so as to connect communication link. (Protect circulation in case of fault power source link or communication link.
2. SNUBBER Circulation: NOISE of over 5V is eliminated through SAC5.0 DIODE.
3. 485 IC (Line Driver/Reeceiver)
● HIGH / LOW is determined through voltage gap between the two electrodes of A and B.
: A-B>200mV : HIGH, B-A>200mV : LOW
● DATA is received and prepared with “R” PORT. When sending the DATA, HIGH is input at ENABLE.

10-5 Q & A for Non-trouble
Classification Class Description
Related to
ventilate
operation
Q Why is the ventilator required? (What is the difference between ventilator and air cleaner?)
A
- Definition : Ventilation is to supply fresh outdoor air to the inside of building and to exhaust indoor air.
(The measures include technological method and natural method.)
- Air cleaner cleans indoor air with system conta
ined in the unit. On the other hand, ventilation
enhances indoor air by replacing indoor air with outdoor air. They can be used according to the purpose
and conditions.
Q Has the effectiveness of ventilator been proved?
A
There is no scientific research to identify the effectiveness of
ventilation. However, it is well known that
opening windows can enhance indoor air quality. If windows open for a long period of time in summer
and winter, it may cause huge heat loss. Thereby, the ventilator is required.
Q Where are ventilators utilized?
A
Ventilator can be us
ed in all spaces within buildings except places with ventilation system such as
bathrooms or kitchens with hood.
Q How the functions can be exchanged?
A The unit supports manual and automatic operation which includes four function modes, according to air
volume. Heat-EX (required in summer and winter) a
nd usual ventilation (optional in spring and fall) are
available
Others
Q What is the function and composition of filter?
A - The unit is equipped with dust filter which protects heat exchange element and prevents dust from
flowing into the inside of building.
- D
eodorizing filters and functional filters are optional. (However, air volume can change due to resistance
blocking air flow of filter.)
Q Replacement period of the Heat exchange element and the filter?
A
Heat exchange element
- Cleaning method and period : clean the e
lement with vacuum cleaner (once in six months)
- Replacement period : If it is not damaged or modified, it can be used permanently because it is made
of paper.
Filter
- Dust filter (Standard) : Clean the element with vacuum clea
ner (once in 6 months)
