• Master unit:

The master unit receives the indoor unit data (thermo status) of the sub

 

(Without identical line address & indoor/outdoor serial) and then finally controls the outdoor

 

compressor matching with its own thermo status.

 

The master unit sends this command information to the sub unit.

• Sub unit:

The sub unit receives the indoor unit data from the master (With identical line address & indoor/

 

outdoor serial) and then performs the thermo operation synchronized with the master unit.

 

The sub unit sends own thermo ON/OFF demand to the master unit.

 

(Example)

 

No. 1-1 master unit sends/receives signal to/from No. 1-2 and No. 1-3 sub units.

 

(It is not influenced by the line 2 or 3 address indoor unit.)

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.

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.
