Energy Savings

By uniting advanced software and hardware technologies for greater energy savings during actual operation and combining the technologies of VRV, VRT and VAV, we have attained both energy savings and comfortable air conditioning.

Automatic Refrigerant Charge Function

The automatic refrigerant charge function* automates the charging of the proper refrigerant amount and the closing of shut-off valves by simply pressing a switch after pre-charging. This function contributes to optimised operation efficiency, higher quality and easier installation.

High Reliability

The control functions of inverter technology have been integrated on printed circuit boards. As well as improving reliability, this has reduced the number of parts and enabled downsizing.
