Possible centralised control systems Daikin DCS302C51

• Centralised control systems

Possible centralised control systems
Centralised control of the system can be achieved via 3 user friendly compact controls: centralised remote control, unified on/off control and schedule timer. These controls may be used independently or in
combination where 1 group = several (up to 16) indoor units in combination and 1 zone = several groups in combination.
A centralised remote control is ideal for use in tenanted commercial buildings subject to random occupation, enabling indoor units to be classified in groups per tenant (zoning).
The schedule timer programmes the schedule and operation conditions for each tenant and the control can easily be reset according to varying requirements.

In the above system, the longest wiring extension is 900 m between A and C, which satisfies the limit of 1,000 m. The total length is 1,100 m, that is
the total of 900 m between A and C and 200 m between B and C, which also satisfies the limit of 2,000 m.
The central controller functions properly, only when both the longest extension and the total length of wiring satisfies the limitation, as shown above.

When designing the system, be sure to check both the longest extension and the total wiring length. If it exceeds the limitation, there is no other
way but to split into several systems.
