[PRECAUTIONS]
There is not need to set the indoor unit address when using
group control. (It is automatically set when the power is turned
on.) However, since the Heat Reclaim Ventilator (outside air pro-
cessing type) uses two remote control addresses per unit, the
number of units which can be group controlled is as follows.
Note:
If a simultaneous cooling system is used, a single BS unit
should connect to Heat Reclaim Ventilator (outdoor air-pro-
cessing type) and indoor units under group control. If a single
BS unit connects to the Heat Reclaim Ventilator unit only, fix
the operating mode of the Heat Reclaim Ventilator unit to
cooling, heating, or ventilation.
10. 6 CONTROL BY 2 REMOTE CONTROLLERS
(CONTROLLING 1 INDOOR UNIT BY 2 REMOTE
CONTROLLERS)
• When using 2 remote controllers, one must be set to “MAIN”
and the other to “SUB”.
MAIN / SUB CHANGEOVER
(1) Insert a flat blade screw driver into the recess between
the upper and lower part of remote controller and, work-
ing from the 2 positions, pry off the upper part.
(The remote controller Printed Circuit board is attached to
the upper part of remote controller.)
(2) Turn the MAIN/SUB changeover switch on one of the
two remote controller Printed Circuit boards to “S”.
(Leave the switch of the other remote controller set to “M”.)
<Wiring Method>

(See “9 ELECTRIC WIRING WORK ”.)
(1) Remove the control box lid.
(2) Add remote controller 2 (SUB) to the terminal block for
remote controller (P
1
, P
2
) in the control box.
(There is no polarity.)
[PRECAUTIONS]
• Crossover wiring is needed when using group control and
2 remote controllers at the same time.
• Connect the indoor unit at the end of the crossover wire
(P
1
, P
2
) to remote controller 2 (SUB).
10. 7 EXTERNAL REMOTE CONTROL
(FORCED OFF AND ON/OFF OPERATION)
• Wire specifications and how to perform wiring
Connect the input from outside to terminals T1 and T2 of the
terminal block for remote controller.

The equipment in Nighttime free cooling operation cannot be
stopped forcibly with T1 or T2.
• Actuation
The following table explains FORCED OFF and ON/OFF
OPERATIONS in response to Input A.
• How to select FORCED OFF and ON/OFF OPERATION
Enter the FORCED OFF and ON/OFF OPERATION selection
using the local “External ON/OFF input” settings based on
“
11 FIELD SETTING AND TEST RUN ”.
10. 8 CENTRAL CONTROL
If control is performed with a central device (central management
controller, etc.), group number needs to be set with the remote
controller. See the manual of each central device for detail.
