Mitsubishi Electric LGH-100RX5 -E, Manual

Page: 70 / 107

C-70
Connect the power supply cable from the Electrically operated
damper to
9
and
0
of the monitor output terminal block (TM4)
with reference to the wire connection diagram.
Operation monitor output with delay function 1 can be possible.
(Refer to function settings 6 (Refer to C-74) “Setting for TM4
90
”)
Note:
• Don’t tighten screws of
terminal block with a
torque larger than
0.5Nm. It could damage
the PCB.
• Response times to external input signals are as shown in
the following table.
■
To force High fan speed externally
When SW1 is "ON", fan speed of the Lossnay will be set to
"High"(Extra-High) regardless of the remote control setting.
Use this in such a way that it ventilates at Low or Extra-Low
fan speed normally, and when the external sensor detects
contamination of indoor air, it changes to High (Extra High)
fan speed operation.
■
To force Low fan speed externally
When SW1 is "ON", fan speed of the Lossnay will be set to
"Low" regardless of the remote control setting.
Use this in such a way that it ventilates at High fan speed
normally, and when the external sensor detect that the indoor
air contamination is low, it changes to Low fan speed opera-
tion.
■
To force Extra-Low fan speed externally
When SW1 is "ON", fan speed of the Lossnay will be set to
"Extra-Low" regardless of the remote control setting.
Use this in such a way that it ventilates at High fan speed
normally, and when the external sensor detects that the
indoor air contamination is low, it changes to Extra-Low fan
speed operation.
* For the LGH-150RX
5
and LGH-200RX
5
types, fan speed of
the Lossnay will be “Low”.

sensor or other
equipment is connected)
Using marketed CO

sensor, etc., make connection by inserting the optional remote display adaptor (PAC-SA88HA-E) in the
connector CN16 (High/Low selector) as shown by the figure.
With SW1 is “ON”, the ventilation mode of Lossnay is changed
to the By-pass ventilation regardless of the setting on the
remote controller.
* When the outdoor air temperature drops lower than 8°C, it
changes to the heat exchanger ventilation. (Display of the
remote controller does not change.)
