Defective → Correct, replace

Check outdoor P.C. board operation.

(See the following description.)

OK

Check 4-way valve.

Defective → Replace

Check outdoor P.C. board.

Defective → Replace

Operation check direction of the outdoor P.C. board (In case of self-preservation valve)

1)Set the Dip switch SW804 as same as the following table and push SW801 for approx. 1 second. It enables you to check the exchange operation to cooling cycle or heating cycle.

•Only for approx. 10 seconds, the power is turned on.

•As the heat value of part (coil: resistance R700) is large, when checking the operation continuously, wait 1 minute or more until the next check. (There is no problem if a coil is not connected.)

2)After check, turn off all the Dip switches SW804.

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.
