!CAUTION
•When installing the control kit, make sure to leave at least 900 mm between the wall and the product case so there is enough room for servicing and installation.
•After mounting the product, check whether it is properly affixed.
•If the control kit has to be installed outdoors, be sure to also install an enclosure.
•When installing load devices such as AHU sensors and dampers outdoors, fitted covers must also be mounted to protect them from the effects of the external environment.
-When using wall mount brackets, fasten the brackets to the four holes on the rear of the enclosure.
-Please use the provided bolts, nuts, and washers to
fasten the brackets.
AHU CONTROL KIT INSTALLATION 11
Things to keep in mind when installing outdoors
-Enclosures should be purchased separately if needed.
-After mounting the product, check the tightness of the connection between the AHU and the enclosure.
If the connection is not airtight, moisture or dust could contaminate the product.
-When installing the AHU outdoors, be sure to use an enclosure to protect the control kit.
-The enclosure should be made of SUS or painted sheet metal to prevent corrosion.
-Make the structure so that it is easy to perform wiring tasks.
-The installation form and location may vary by site.
-Panels installed outdoors must be installed in a place that is not exposed to direct sunlight.

16 OUTDOOR UNIT COMMUNICATION LINE CONNECTION
OUTDOOR UNIT COMMUNICATION LINE CONNECTION
Cautions on connecting the EEV module (communication
module) with outdoor unit |
|
|
|
<![if ! IE]> <![endif]>B- |
- The Control Kit comes mounted with three EEV modules, |
|

<![if ! IE]> <![endif]>IDU B |

|
|
and each EEV module can be connected to one Expansion |
|
|||
|
|
|
|
|
Kit. |
|
|
|
|
If additional EEV modules are required depending on the |
|
|
|
|
number of outdoor units, they must be purchased |
|
|
|
|
separately and installed. |
|
|
|
|
- Make sure the communication cables of each outdoor unit |
|
|
|
|
and pipe thermistor wires of Expansion Kit are not mixed |
|
|
|
|
when connecting the outdoor units. |
|
|
|
|
Capacity Control Communication Cable Connection
-In order to control the SA temperature in the control kit, the central control communication line must be additionally connected. Please refer to the wiring diagram and the figure below for details.
-For models without a central control communication modem, a central control communication modem must be installed separately to control the supplied air's temperature.

!CAUTION
•The AHU Control Kit can control the temperature of the supply air by connecting to up to three outdoor units. When connecting outdoor units, the communication addresses should be set from 1 to 3, sequentially.
Otherwise, the supply air temperature control function may not work properly.
•Make sure the polarity of the power supply connector is correct when connecting the communication cable between the Control Kit and outdoor unit.
•DIP SW 3 of the outdoor unit must be turned off in order to ensure communication between the control kit and the outdoor unit.
•When connecting to Multi V Super 5, Function FN39 must be set to Option1. (Dip switch No.5 ON → FUNC → FN39 → OP1) Please refer to the Multi V manual for details on Multi V Function settings. (Applicable to both ventilation temperature control and supply air temperature control)
