8 CONNECTION OF EXTERNAL SIGNALS When connecting external signals, refer to the Installation Instructions (end of this manual) for detailed information about the electrical specifications. 8.1 Pulse Meter Input You can measure energy usage by connecting pulse meters (gas, fuel, and electricity meters). If you do not need to view information about energy usage, there is no need to install pulse meters.
8 CONNECTION OF EXTERNAL SIGNALS 8.2 All Stop Input You can stop all connected units automatically by connecting external signals (for example, from fire-alarm detectors.) All stop input is available only for managed (“target”) units. It does not affect units which have been designated as not managed (“Not target”) or individually operated (“Indiv Op”).
8 CONNECTION OF EXTERNAL SIGNALS 8.4 All-Unit Alarm Output An external signal is output when an alarm or error occurs in any connected unit. This signal can be used by alarm monitors and other equipment. 1) Output location The communications connector panel on the side of the Intelligent Controller or on an optional communication adaptor connected to the Intelligent Controller: DO1, DO-COMM 2) Operation The signal goes ON when an alarm or error occurs, and goes OFF when normal status is restored. 8.
9 TERMS This section explains some of the terms used in this manual. ■ Adaptor address (No. 0 set on Intelligent Controller, No. 1 to 7 set on communication adaptors) An adaptor address is the address assigned to an optional communication adaptor. ■ Link system address (No. 1 to 2, fixed) A link system is a collection of indoor units and outdoor units connected to a single inter-unit control wire.
10 CALCULATING AIR CONDITIONER DISTRIBUTION The Intelligent Controller calculates energy (electricity and gas) distribution ratios utilizing the accumulated working time (T/S ON/OFF) or the capacity value of the indoor unit. * T/S: Thermostat 10.
10 CALCULATING AIR CONDITIONER DISTRIBUTION Calculate electricity/gas usage index of entire distribution group Let “TOTALe” be the electricity usage index of entire distribution group, and let “TOTALg” be the gas usage index of entire distribution group. Let “m” be the number of indoor units in the distribution group.
