5 - 2 Detailed Explanation of Functions
5 - 2 - 2 Control, Operation, Settings
(4) Schedule control
Automatically performs starting and stopping of any control group and management items according to the set time schedule.
Creating and registering a year calendar and a week schedule will automatically create an execution schedule and the specified management items
and control groups are controlled according to that execution schedule. Also, by editing the execution schedule, the schedule for the next coming week
can be specially changed.
A maximum of 128 programs can be registered.
The year calendar, week schedule and execution schedule are in parity of 1 to 1, and schedule operations can be executed by combining each one.
Year Calendar:
13 month calendar. Can set for regular days, holidays or special days for each day and allows creation of customized calendars for each tenant.
Week Schedule:
Registers the times for performing control from the intelligent Manager for any control group or management item individually, for each day, holiday or
special day of the week. Specify either of the instructions, run, stop, enable remote controller, disable remote controller, fan, cool, heat operation mode
or set point.
Registers up to 20 actions per day.
Execution Schedule:
Daily schedule for the coming week. The actual schedule runs according to this. Automatically created based on year calendar and week schedule.
With the execution schedule, you can change anytime to correspond to the remaining hours to run and other specially made schedules.
(5) Interlocking control
Automatically starts and stops equipment that has been set according to the change in operating status of specified equipment or the occurrence of
abnormality. There are 2 types of input conditions that can be specified: "Start/Stop Status" and "Error"
Using link control allows for starting and stopping links (sequential operation etc) for a plurality of facilities, indoor/outdoor units links, key control links
and reporting.
A maximum of 50 input condition management items and a maximum of 50 start/stop output management items can be set with 1 link program. A
maximum of 200 link programs can be defined.
The application of a plurality of link programs for input and output with the same management items is possible.
Example of Interlocking Programs: Indoor unit Link: Inputs signal from lighting equipment and turns OFF air conditioning of rooms where all lights have
been turned OFF.
Key Control Link: Inputs signal from key control device and turns OFF lights and air conditioning of areas from which keys have been returned.
(6) Emergency stop control for fires
The system performs the necessary determined actions (rings buzzer, prints to printer, display fire sign, stops air conditioning equipment, etc) to notify
of fires and to prevent the spread of flames when a fire signal is input. These fire related actions take priority over normal actions.
Though similar to linked operations, a major difference is that the content of the output is limited to the stop instruction. The emergency stop takes
priority with regard to control.
Registering the management items to be the target of an emergency stop can be done by specifying the management items to stop or by targeting all
management items for a stop and then specifying the management items that are an exceptions.
A maximum of 32 programs can be set.
The fire warning system controls smoke detectors and dampers according to fire prevention laws. Elevators, etc are controlled by a dedicated control
system.
Therefore, these facilities are not targeted for control by the emergency stop program.
