Page 27: Individual Control Systems
PC-ART is the standard individual remote control of HITACHI. PC-ARF is the newest individual remote control of HITACHI, with an attractive design, excellent display thanks to its large sized LCD screen and with new additional optional functions.
Page 28: Wireless Remote Controls
2 Control solutions Great control possibilities 2.2.1.2 Wireless remote controls Wireless remote controls are the most suitable option for those users who are only interested in basic functions (ON/OFF, setting temperature, fan speed and louvre direction). Optional functions cannot be set by wireless remote controls. These remote controls do not require electrical connection between the remote control and the indoor unit, since they are wireless.
Page 29: Centralised Control Systems
Centralised remote controls are ideal for use in installations subject to random occupation, enabling indoor units to be clas- sified in groups by each considered zone. HITACHI recommends the use of centralised remote controls for controlling a high number of indoor units distributed throughout one floor of a building.

Page 38 Multitenant installations HITACHI offers the PC-AMTB control support for multitenant buildings (office buildings, multi dwelling, small hotels) with several indoor units of different tenants with a common shared outdoor unit. Thanks to the PC-AMTB, the power supply of some indoor units can be shut-down without causing refrigerant problems, since the expansion valve of such indoor unit is controlled to adjust the refrigerant flow accordingly.
Page 39 2 By the temperature value at the thermistor of the remote control (If available). 3 By the average between both previous values. Moreover, HITACHI offers the remote temperature sensor THM-R2AE in order to provide more options for the room tem- perature measurement. In this case, the room temperature value is obtained as follows: 1 By the average between the air inlet temperature value at the indoor unit and the temperature detected at the remote sensor.

Page 575 6 Building air conditioning controls CSNET Manager LT/XT Unit configuration The unit settings show all the data of each of the units controlled by CSNET Manager. The information given is as follows: • Indoor Unit Location: Name of the room conditioned by this unit. Area: Zone to which this unit belongs.
Page 576 6 Building air conditioning controls CSNET Manager LT/XT OU Serial No: Serial number of the outdoor unit to which the indoor unit is connected (see Note 2). • TSet Limits Cool Range: Sets the maximum and the minimum temperature values in cool mode. Heat Range: Sets the maximum and the minimum temperature values in heat mode.
Page 577 6 Building air conditioning controls CSNET Manager LT/XT Auto cool/heat The outdoor units of 2-tube systems and are not designed to operate in the automatic Cool/Heat mode when more than one indoor unit is connected to the same outdoor unit, but only in the cool or heat mode. Thus all indoor units connected to the same outdoor unit should be changed from one mode to another at the same time.
Page 578 6 Building air conditioning controls CSNET Manager LT/XT Description of the operation mode In the automatic (Auto) Cool/Heat mode requested by the indoor units, CSNET will check first whether the cooling circuit to which the unit is connected is 2 tube or 3 tube before deciding to change the operating mode. Then, CSNET WEB calculates the difference to decide the best operation mode at that moment.
Page 579 6 Building air conditioning controls CSNET Manager LT/XT Description of parameters To use this option, you have to set the parameters shown in the Auto Cool/Heat operation panel. After that, if unit is working in Auto Cool/Heat mode, you can see the status of this operation on the status zone of the panel. The Auto Cool/Heat panel shown corresponds to the cooling circuit of the indoor unit selected in the table of indoor units, as shown in the example.

If the selected temperature is higher, CSNET will use USERMAX as the value for the Setting temperature, changing this value as soon as the operation mode changes. Pre set adjustment: +25°C.
Page 582 6 Building air conditioning controls CSNET Manager LT/XT Fan stop heating during thermo-off N O T E This function is only available for HC-A64NET units. In VRF systems, when unit is heating thermo-off CSNET Manager can stop the fan. Configurable parameters: Enabled: enables the fan stop function Master unit: field for selecting the method CSNET Manager will use to calculate the temperature difference.
Page 583 In VRF systems, when load is very low and only few units are working in a system, it is possible that discharge air temperature is reduced below comfort value. With this new option HITACHI improves comfort for these situations by setting unit to Fan Mode when discharge air temperature is below comfort temperature and set unit again to Cooling Mode when temperature will be again inside comfort range.
Page 584 6 Building air conditioning controls CSNET Manager LT/XT Outdoor control Outdoor control panel let user set up the following outdoor functions: • Power control: limit the power consumption of the outdoor unit. • Night mode: reduce the unit sound. It is useful during the night. N O T E The list of outdoor units only shows the outdoor units that supports this type of control.
Page 585 C A U T I O N • Suggested device tested by Hitachi is 7KM PAC3200 by Siemens. • Ensure that your Modbus-TCP power meter register starts at 0. CSNET Manager considers it like this, so if it starts at 1, subtract 1 to each register address.
