1. SINGLE SPLIT INVERTER AIR-CONDITIONER
Next we will look at new single split package air-conditioners of MHI in 2008.
More important, we will have a new designed indoor unit this year, the new ceiling cassette -4way- indoor unit FDT, which will replace the present one. ♪

Firstly, let’s look at the line-up of our new PAC.
We have a new model for 1.5, 2.0 & 2.5HP outdoor units, ZIX-S, which is the replacement of the previous SRC**ZHX-S. ♪ X X 5 5

As you may noticed, our new model names are a bit different from the previous FD series.
For example, the 6HP model FDC140VN/S. ♪
Letter FD, keeping the same meaning of the existing one, shows the symbol of single split PAC.
Letter C is the symbol of outdoor unit.
The digits after C show the nominal capacity of the unit as we mentioned just now.
As for 8HP unit, 200 means 20 kilowatts, and 6/5/4 HP models respectively show 140/125/112 in their model names. 3HP equals to 7.1 kilowatts which show 71 in the model name.
Letter V is the symbol of inverter compressor.
Letters N/S mean the different power source. N means single phrase and S means three phrases.

As we have mentioned earlier, RAC&PAC models can be connected into the superlink network and work together with our VRF system in the same superlink network as well. But some interfaces will be needed for the connection.
Here is the list of optional kits, which is using for RAC&PAC models connection to superlink network.
There are three different models.
Remote Controller adapter will be applied when RAC units are needed to be controlled by wired remote controllers. SC-BIK1-E is using for SRK**ZG-S models controlled by the old RC-E1R, while SC-BIKN-E is connecting SRK**ZHX-S or the new SRK**ZIX-S models to the new 2-core controller RC-E3.
Superlink adapter SC-AD-ER & SC-ADN-E are using for RAC/PAC systems to connect into superlink network. SC-AD-ER is used for the previous superlink 1 and 3-core wiring remote controller RC-E1, while SC-ADN-E is used for the new superlink 2 and 2-core wirings remote controller RC-E3.
Remote sensor SC-THB-E3, which is a wildly used remote sensor, can change to the remote detected temperature instead of the original temperature of intake air. It is available for all of our new KX6 & PAC indoor units. ♪

Here we can see the superlink network structure including KX6, PAC & RAC. ♪
As we all know, the new superlink network applies 2-core wirings connecting outdoor unit, indoor units and centralized remote controllers as SC-SL1N-E & SC-SL2N-E.
RAC series such as SRK50/60ZHX-S are using 3-core wirings for connecting o/u & i/u.
As we mentioned in the previous slide, SC-BIKN-E should be connected as an adapter when RAC model is controlled by RC-E3.
When RAC is connected into the new superlink network, it must be connected through SC-ADN-E to the new protocol network, and 2-core wiring is applied.
In terms of PAC series, 3-core cable is using between the outdoor unit and indoor units.
Again, same as RAC units, SC-ADN-E should be connected between PAC units and superlink network. 2-core wirings are applied.
Now let’s look at the detail of each kit.

SRK63/71ZE-S1, SRK63/71HE-S1, SKM60/71ZG-S & SRRM, STM models don’t need interface to be controlled by RC-E1, the previous wired remote controller.
ZG series from 20 to 50 of SRK & SKM models need to be connected with SC-BIK1-E when controlled by RC-E1.
When connecting with the new wired remote controller RC-E3, it is necessary for SRK50/60ZHX-S & the new series SRK**ZIX-S models to be connected with the new superlink protocol’s interface kit SC-BIKN-E. ♪
As we have seen, when RAC&PAC units connected into superlink 2 network, both SC-BIKN-E & SC-ADN-E are needed to connect with the indoor units.

Another optional kit remote sensor SC-THB-E3, as we explained earlier, could be using when it is necessary to change the original intake air temp sensor to the remote one.
It is only available for KX6 and new PAC units. ♪
The original intake air temperature sensor now could be changed to the cable connection, of which max length could be 8 meter.
Or change to selectable from indoor side of remote control.
Exterior is described as these dimensions, 70mm’s high, 25mm’s wide and 15mm’s deep with the colour of ivory.
