Power proportional distribution System Architecture Confirmation of Watthour Meter For distribution of electric energy, the integrating watthour meter with pulse transmitter is required. It is important to confirm that the specifications coincide with each other, and also to confirm with the division in charge (normally, electrical work division, not air-conditioning div.).

(The group address for sub-unit can be set in the site set mode “30” of the remote controller.
• intelligent Touch Manager • ED721208 Setting of Each Electric Power Group Watthour meters have to be installed for Heat Pump type VRV and Heat Recovery type VRV respectively as shown below figure and make power groups respectively.
• intelligent Touch Manager • ED721208 The Reason why VRV Heat Recovery must not be Included For Heat Recovery outdoor units, the watthour meter must be independently installed. (1) For heat recovery, there is a case that the power consumption is less than VRV and VRV Plus. (2) However, if different systems are put on the one meter, the electric power distribution would be calculated by constant counting, and the calculation result would then more than the actual value on all indoor units.
• intelligent Touch Manager • ED721208 Explanations of Power Proportional Distribution What is the Power Proportional Distribution (PPD) (System Ex. : Normal VRV) Since this system detects power consumption as the base of billing, specified watthour meters should be used by all means.
• intelligent Touch Manager • ED721208 2) Counting the electricity at the stopped condition of the unit Even if a VRV is stopped or in the condition of thermostat -OFF (the condition that the compressors are stopped as the temperature in the space where all the indoor units are installed falls down to the set temperature), the VRV consumes energy due to the energy consumption mainly by the crankcase heater in the outdoor unit.

• intelligent Touch Manager • ED721208 iTM counts the power consumption as the following conditions (1)~(6) for the standards. So, the gap to be raised from these conditions may cause the error. Since these errors vary depending on the surrounded situations, the worst error value cannot be drawn out from the computing.
• intelligent Touch Manager • ED721208 Notes • It is not possible to apportion power consumption for the VRV series indoor unit FXUQ (ceiling suspended cassette type). (Reason) VRV and SkyAir use different methods to calculate thermo step, which is a parameter necessary for power consumption apportionment. For the VRV, the indoor unit calculates thermo step. Whereas for the SkyAir, the outdoor unit calculates thermo step.
• intelligent Touch Manager • ED721208 Reference Material Case Examples (1) A value on a wattmeter of each outdoor unit system does not correspond to PPD result. Electric power of wattmeter A is nearly the same as that of wattmeters B + C + D. However, the PPD result of outdoor unit system 1 (4 indoor units) does not correspond to the value on wattmeter B. [Reason] An intersystem difference causes this problem. The PPD function does not recognize how many outdoor units exist in an electric power group.
• intelligent Touch Manager • ED721208 (2) A group address is not set to a slave indoor unit with remote controller group. iTM cannot control slave indoor units (Indoor units B, D, G, and H in the following figure) in remote controller group. In general, the setting of a group address is not required for control with a remote controller group. However, it is necessary to set a group address even to slave indoor units and register it with a power group at PPD setup because a thermo.
• intelligent Touch Manager • ED721208 (3) A PPD calculation result for a certain tenant is excessively large. iTM distributes electric power based on operation data from an indoor unit. If only one VRV indoor unit is in operation, electric power consumed by an outdoor unit increases because a compressor is turned ON only for one indoor unit in operation.
• intelligent Touch Manager • ED721208 6. Design of DIII-NET Features of DIII-NET What is DIII-NET? DIII-NET is a proprietary high-speed communication method developed by Daikin, with which huge amount of information can be transmit at high speed and various facilities of a building, such as air conditioners, can be freely connected via networks in accordance with the usage, scale, and conditions.
• intelligent Touch Manager • ED721208 Connection Method Correct Wiring • Series wiring method only should be used. [Example] Connect indoor units and outdoor units without branch connection. Indoor-outdoor connection VRV Outdoor unit IN/OUT F1 F2 OUT/OUT F1 F2 VRV Indoor unit Connect outdoor units without branch connection. IN/OUT F1 F2 OUT/OUT F1 F2 IN/OUT F1 F2 OUT/OUT F1 F2 Connect the centralized control equipment to the outdoor-outdoor connection.
• intelligent Touch Manager • ED721208 Wiring Example Example of Control Wiring • • Be sure to connect the wiring of the centralized control equipment to control wiring between outdoor units. When wiring connections are made between indoor and outdoor units, there may be cases where control over normal systems may become impossible if one of the connected systems should happen to fail. Be sure to prevent the connection of three wires on the same terminal.
• intelligent Touch Manager • ED721208 When the centralized control equipment are located at several places. iTM A A Control wiring between indoor unit and outdoor unit Outdoor unit (α1) (α1) System1 It is possible to operate without remote controller. (when the central remote controller is employed.) (α2) Possible to control group operation of up to 16 indoor units. Group control is set by the automatic address setting.
• intelligent Touch Manager • ED721208 Wiring Length • • Total length must be 2000m or less. (The total wiring length is 1500m when shielded wire use.) Max. length must be 1000m or less. [Example] 200m Outdoor unit Indoor unit 100m 10m 500m 10m 200m Max. length 200+10+10+500 =720m Total length ≤ 2000m Max. length ≤ 1000m Therefore, the limitations on length are satisfied.
• intelligent Touch Manager • ED721208 Cautions: 1. Never use a 3 or more core of cord or cable. 2. The size of wire should be 0.75~1.25mm². 3. Never bundle the cable or cord of transmission line. 4. Be sure to keep the transmission wiring distant from power wiring as shown below to prevent electrical noise.

• intelligent Touch Manager • ED721208 Number of Connectable Units Number of Units to be Connected [VRV] (Supplementary Explanation) • Up to 10 VRV outdoor units can be connected to DIII-NET. - In case of VRVII and VRVIII, an outdoor unit which consists of multiple modules is counted as one unit. Each module is counted as 1 unit. 2-unit module • 3-unit module Up to 64 VRV indoor unit groups can be connected to DIII-NET.
• intelligent Touch Manager • ED721208 Connection of Devices other than VRV • • You can connect adaptors and other devices (SkyAir adaptor, RA adaptor, Di/Dio units, etc.), which are not VRV, to either indoor-outdoor connection or outdoor-outdoor connection. You cannot connect a chiller (which accommodates DIII-NET) to the same DIII-NET to which VRV, SkyAir, and RA are connected.
