1. INTRODUCTION

1.1 General

The Trio/Quattro DCI Multi series is a full line multi-tubing system with 3 to 4 connected indoor

units. The multi-split inverter is a high level technology product for residential and commercial

application offering comfort, low noise operation and energy saving.

1.2 Main Features

1.2.1 High Technology

• Sine wave form in both OFAN and Compressor drives.

• DC-BL-SL (Sensor less) Inverter Compressor drive.

• DC-BL Inverter OFAN drive in the controller.

• DSP Power (Digital Signal Processing) – High speed calculation for accurate Sine wave

form vector control.

• Smart PFC control.

• Fuzzy Logic Control

1.2.2 System Features

• R410A

• High COP (“A” class energy rating)

• Low noise levels

• IAQ (Indoor Air Quality) features (WNG series)

• Lego concept - Products line of wall mounted, ﬂoor/ceiling, cassette, ducted with capacity

models of 2.5, 3.5 and 5.0 kW.

• Networking connectivity.

• Pre-charged system.

• Dry contact inputs:

o STBY

o Night (in cool mode only)

o Power Shedding

o Forced Mode operation

• Dry contact output – Alarm.

• Ready for Base heater connection and logic.

• Cooling operation at outdoor temperature down to -100C.

• Heating operation at outdoor temperature down to -150C.

• HMI Display Board (Human-Machine Interface) – 3x7-segment display shows both indoor

and outdoor diagnostics and setting up features.

• Monitoring softwear(PC port).

• EEV (Electronic Expansion Valve) for each indoor unit.

1.3 Tubing Connections
