Hitachi offers the CS-NET system, which is a control system designed to centrally control one or more air conditioning units from a locally installed central computer. An external access via modem allows remote control of the system. Through this system, air conditioners of different Hitachi product series (Set Free, Utopia, Utopia Big...) can be simultaneously connected
CS-NET system can be connected to a Pentium processor, with 8 MB RAM, Windows 95 or 98. The software program is supplied on just 2 diskettes.
One computer (COM Port) is able to control up to 16 UTOPIA series Systems (16 units or 16 groups of outdoor and indoor units); the system is connected to the indoor unit.
On the figure below it can be seen the HITACHI CS-NET Wiring Diagram. Wire Color Red Data White ... Black 0 INDOOR UNITS

■Do not install the indoor unit in a flammable environment to avoid a fire or an explosion
■Check to ensure that the ceiling slab is strong enough and that the false ceiling is flat and level.
■Check to ensure that the instruments are all suited
■Do not install the indoor unit outdoors. If installed outdoors, an electric hazard or electric leakage will occur.
■Do not install the indoor unit, outdoor unit, remote control switch and cable within approximately 3 meters from strong electromagnetic wave radiators such as medical
equipment.

Fig. 15.2: Installation location of Indoor Unit
■Consider the air distribution from the indoor unit to the space of the room, and select a suitable location so that uniform air temperature in the room can be obtained. It is recommended that the indoor unit be installed 2.3 to 3 meters from the floor level. If the unit is installed higher than 3 meters, it is also recommended that a circulator be utilized to obtain uniform air temperature in the room.
■Avoid obstacles which may hamper the air intake or the air discharge flow.
■Do not install the indoor unit in a machinery shop or cooking room where vapor from oil or mist flows to the indoor unit. The oil will deposit on the heat exchanger, thereby reducing the indoor unit performance, and may deform. In the worst case, the oil breaks the plastic parts of the indoor unit.
■Pay attention to the following points when the indoor unit is installed in a hospital or other places where there are electronic waves from medical equipment, etc.
− Do not install the indoor unit where electromagnetic wave is directly radiated to the electrical box, remote control cable or remote control switch.
− Install the indoor unit and components as far as practical or at least 3 meters from the electromagnetic wave radiator
− Prepare a steel box and install the remote control switch in it. Prepare a steel conduit tube and wire the remote control cable in it. Then connect the ground wire with the box and tube.
− Install a noise filter when the power supply emits harmful noises.
■To avoid any corrosive action to the heat exchangers, do not install the indoor unit in an acid or alkaline environment.
