Indoor unit No.

: N – n = Outdoor unit line address N (Max. 30) – Indoor unit address n (Max. 64)

Group address

: 0

= Single (Not group control)

 

1

= Header unit in group control

 

2

= Follower unit in group control

Header unit (= 1) : The representative of multiple indoor units in group operation sends/receives signals to/

 

from the remote controllers and follower indoor units.

 

(*It has no relation with an indoor unit which communicates serially with the outdoor units.)

 

The operation mode and setup temperature range are displayed on the remote controller

 

LCD. (Except air direction adjustment of louver)

Follower unit (= 2) : Indoor units other than header unit in group operation

 

Basically, follower units do not send/receive signals to/from the remote controllers.

 

(Except errors and response to demand of service data)

Master unit

: This unit communicates with the indoor unit (sub) which serial-communicates with the

(Representative unit)

outdoor units and sends/receives signal (Command from compressor) to/from the outdoor

(Header Twin)

units as the representative of the cycle control in the indoor units of the identical line

 

address within the minimum unit which configures one of the refrigerating cycles of Twin,

 

Triple, Double twin.

Sub unit

: Indoor units excluding the header unit in Twin, Triple, Double twin

(Subordinate unit)

This unit communicates with (Master) indoor unit in the identical line address and performs

(Follower Twin)

control synchronized with (Master) indoor unit.

This unit does not perform the signal send/receive operation with the outdoor units.:

N judgment for serial signal error.

Toshiba has long been a name associated with innovative and efficient HVAC solutions, and their Concealed Duck Type, Ceiling Type air conditioning units exemplify this legacy. These units are designed to provide exceptional comfort while seamlessly integrating into a variety of interior spaces.

One of the main features of the Toshiba Concealed Duck Type, Ceiling Type system is its discreet installation method. Unlike traditional wall-mounted units, this system is installed within the ceiling, allowing for an unobtrusive appearance. The result is a clean and modern aesthetic, ideal for residential and commercial settings where design is a priority. With only the supply and return grilles visible, the units maintain the integrity of the interior decor.

The technology employed in Toshiba's air conditioning systems revolves around energy efficiency and user comfort. The units are equipped with inverter technology, which allows for precise temperature control and reduces energy consumption. The inverter adjusts the compressor speed to meet the cooling or heating demand, ensuring not only optimal comfort but also reduced operational costs.

Another significant characteristic of the Toshiba Concealed Duck Type units is their quiet operation. Designed with sound-dampening features, they operate at low noise levels, making them suitable for environments where noise can be a concern, such as offices, hotels, or residential spaces.

Toshiba's advanced air filtration system further enhances indoor air quality. Integrated filters capture dust and allergens, creating a healthier indoor environment. This is particularly beneficial for individuals with allergies or respiratory concerns, as the system works to reduce airborne pollutants.

The units also offer flexible control options. With the availability of remote control or smart home integration, users can easily adjust settings to suit their preferences. Additionally, some models come with programmable timers, allowing for energy savings when the space is unoccupied.

Furthermore, these units are designed for reliability and ease of maintenance. Toshiba emphasizes durability in their construction, and the concealed installation not only enhances aesthetics but also protects the unit from potential damage. Routine maintenance can be performed efficiently, ensuring longevity and sustained performance.

In summary, Toshiba's Concealed Duck Type, Ceiling Type air conditioning units deliver a blend of innovative technology, energy efficiency, and contemporary design. With features like inverter technology, quiet operation, advanced air filtration, and flexible control options, they offer a compelling choice for those seeking comfort without compromising style. These units stand as a testament to Toshiba's commitment to quality and customer satisfaction in the HVAC industry.
