Features This unit is a centralized air conditioning management system designed for use with precision air conditioning systems (PAC, air conditioning systems for ofces and shops, and multi-unit systems for buildings) and gas heat pump (GHP) air conditioners.
z With one of these units you can connect and control up to 128 indoor units (2 systems of 64 units each) and 60 outdoor units (2 systems of
30 units each).
z By connecting a communication adaptor this can be increased to 256 indoor units and 120 outdoor units. z The unit is equipped with a 10.4-inch TFT colour touch panel display (1024 x 768 dots), enabling control by almost anyone.
Operation and status
P.23
You can check to operational status (ON/OFF, operating mode, alarms, etc.) of all indoor units and outdoor units in real time. You can also select indoor units to change their settings.
Distributing air conditioner energy
P.71
You can view cumulative operating times for indoor units, engine operating times for outdoor units, and operation cycles in a list. (Cumulative values) Using these data, you can calculate the distribution ratio of electricity or gas consumed for air conditioning and volumes used (kWh, m
3
) per indoor unit or in an area, then show
these calculations in a list.
Operation scheduling
P.39
You can register daily operation schedules (ON/OFF time, operating modes, set temperatures, etc.) for individual indoor units or groups of indoor units. Operations can be schedule for up to 2 years in advance.
Remote control
P.122
The LAN terminal on this unit enables you connect it to a network. Connecting to Internet will enable you to operate the unit and check the status using a PC from a remote location.
