(b) Elimination of temperature irregularity as the time of operation ON/OFF control
• The system finely controls the compressor to room temperature according to the temperature sensor, air conditions room
temperature consistently and improves cooling or heating feeling in each room (or minimize influence of shutdown in
other room).
(2) Super lynk system
• Non polar 2-core signal wires for indoor, outdoor units by means of the automatic polarity selection.
• In addition, the max. 48 units can be controlled with a pair of signal wires. The high speed transmission method same as
the computer network system [start up of 48 units can be completed within a few seconds by the determination of operation
mode and the start of operation].
• As separate power supplies for the indoor and the outdoor units are employed, a pair of 2 signal wires only are required for
the inter connecting wiring of indoor and outdoor units regardless of the number of units so that the installation work can
be simplified, the cost of wiring work can be curtailed and causes of wiring error can be minimized.
