Simple to Install

The Installation of Piping and Power Supply for All Units from 8HP to 30HP is Extremely Simple.

The outdoor unit for 8HP to 20 HP models has been
simplified to a single module. On top of this, the messy
piping connections and wiring for installations of up to
30HP have been greatly reduced through the combination
of 2 outdoor units.


Simple to Install and Cost Effective Communications Network

A two wire non-polarised transmission line allows for the simple and fool proof connection of each indoor unit and remote controller to the network.


With the additional benefit of being able to install each remote controller anywhere on the network, the electrical installation can be kept to a minimum and hence cost savings achieved.
 Example of Batch Changes

World's First and Only Two-Pipe Simultaneous Heating and Cooling System Greatly Enhances Piping Efficiency.

Our unique heating and cooling circuit system combines the "R2 refrigerant circuits" with fuzzy logic to allow for independent dispersion and cooperative control to achieve simultaneous cooling and heating using 2 pipes: one for high pressure and one for low pressure.

This has made the free selection of either heating or cooling on an indoor unit basis, savings in space required for pipes, and a reduction in construction possible.
 Comparison of piping connection sites

Installing the BC Controller
Up to 16 units can be connected to the P20-P140 indoor model units and a single outdoor unit using a single refrigerant circuit. Moreover, the indoor units can be connected within the range of 50-150% of the outdoor unit's capacity (in cases where the refrigerant line extension is 90m or less).
