5 Survey of various control systems
For more effective localized environmental control Daikin offers various control systems such as single or double remote control or centralized control.
This enables the construction of a variety of operational control systems which can be adapted for various uses from remote control to building
automation (BA).
Control Method Objective / use System outline Function Standard number of units
DST301B51 Schedule timer
To carry out weekly schedule operation by 1- minute units
• ON/OFF time can be set by units of day, hour and
minute; ON/OFF pattern can be set by time zone of twice per day in accordance with application.
Simultaneously controls 64 groups with one schedule timer. Max. 128 units
Centralised remote control DCS302B51
To control all indoor units from one place
• Double central control function • Function of liquid crystal remote control can be
controlled individually for each zone of the indoor unit.
• Individual/ unified operation • Up to 8 patterns can be set for operation controlled
by programmed time when used in combination with schedule timer.
• Temperature setting for each zone • Control operation for each room during centralized
control
• Remote control operation rejected command • Sequential start function
Controls up to 64 groups with one centralised remote control. Max. 128 units
Unified ON/OFF control DCS301B51
• Double central control function • Indoor unit ON/OFF control • Individual/unified operation • Remote control operation rejected command.
(Centralised remote control given priority when used in combination with centralised remote control.)
• Sequential start function
Controls up to 16 groups of indoor units with one unified ON/OFF control. Max. 128 units
• Schedule timer • Centralised
remote control
• Unified ON/OFF
control
• Respective functions of schedule timer,
centralised remote control and unified ON/OFF control are possible. (Control mode of centralised remote control is given priority for operation of remote control for indoor unit.)
• Sequential start function.
Controls up to 64 groups of indoor units with 1 schedule, timer, 2 centralised remote controls and 8 unified ON/OFF controls.
Max. length of transmission wiring for centralised control: 1 km
