6.5. Airfl ow changing
When using the unit with external static pressure under 25 Pa, the connector must be
replaced as explained below.
Replacement method (see Fig. B)
(1) Remove the Wire (Type A) connector from Wire (Fan motor).
(2) Remove the Wire (Type A) connector from CN4 of the PCB.
(3) Insert the Wire (Type B) connector into CN4 of the PCB.
(4) Insert the Wire (Type B) connector into Wire (Fan motor).

Controller PCB
Output terminal (CNB01)
(1) External input
• Indoor unit can be Operation/Stop or Emergency stop or Forced stop by using indoor
unit PCB CNA01 or CNA02.
• "Start/Stop" mode or "Emergency stop" mode or "Forced stop" mode can be selected
with function setting of indoor unit.
• Indoor unit can be Forced thermostat off by using indoor unit PCB CNA03 or CNA04.
• A twisted pair cable (22 AWG) should be used. Maximum length of cable is 150 m.
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• The wire connection should be separate from the power cable line.
Input select
Use either one of these types of terminal according to the application. (Both types of
terminals cannot be used simultaneously.)
● Apply voltage terminal ([CNA01], [CNA03])
When a power supply must be provided at the input device you want to connect, use the
Apply voltage terminal ([CNA01], [CNA03]).

*1 Make the power supply DC12 to 24V. Select a power supply capacity with an ample
surplus for the connected load.
Do not impress a voltage exceeding 24V across pins 1-2, and 1-3.
*a The allowable current is DC 5mA to 10mA. (Recommended: DC5mA)
Provide a load resistance such that the current becomes DC10mA or less.
Select very low current use contacts (usable at DC12V, DC1mA or less).
*b The polarity is [+] for pin 1 and [-] for pin 2 and 3. Connect correctly.
When connected to Apply voltage terminals of multiple indoor units with a connected unit,
be sure to make a branch outside the indoor unit using a pull box, etc. as shown on below
example.
