Control Devices EDUS39-60548 Controls2.6 DST301BA61 Schedule TimerEnables you to connect and control weekly schedules for up to 128 indoor units.2.6.1 System Configuration and Electric WiringWith a schedule timer, you can set on/off time twice a day in time increments of 1 week for up to 128 indoor units. System ConfigurationIf using the schedule timer alone, you don’t have to set the centralized control group number. Transmission WiringIndoor Unit Wiring:1. If using the schedule timer alone: For the schedule timer’s power supply, connect the schedule timer (D1, D2) with the connector (X18A) on the indoorunit PC board by crimped style terminal with the attached electrical wire.2. If using in combination with other optional controllers for centralized control:Transmission wiring for control: AWG 18 , 2-conductor, stranded, non-shielded copper cable / PVC or vinyl jacket, Max.3280 ft (Total Max. 6560 ft)Transmission Wiring Connection Example:1 series wiring, 2 bus wiring, and 3 star wiring are the same style asthe central remote controller. Simultaneous control of up to 128 indoor units is managed by aweek schedule. The start and stop time for twice a day can be set for the week inincrements of 1 minute. By combining with a central remote controller and schedule timer,you can construct a system that matches the size and use of thebuilding. If used together with a central remote controller, you can set up to 8schedule patterns that can be distributed among zones using thecentral remote controller. Is equipped with a compensation function for power failure up to 48hours. Features thin design of a mere 5/8" in thickness using JIS recessedbox for 2. Applicable wiring methods include bus and star in addition tocrossover type. Can be used in combination with other D-BACS equipment.
