1. INTRODUCTION
CONTENTS
1.1 General
The new 4-5-6HP DC INVERTER ducted split unit range comprises the following RC
(heat pump) models:
• DNG 100
• DNG 125
• EMD 100
• EMD 125
• CD 140
Remote control compatibility
The units are compatible with remote controls RC3, RC4, RCW1, RCW2, RC7.
Inverter description
Unlike standard units (fix RPM) that are selected according to their nominal capacity to
overcome the maximum required load, DC Inverter units can be selected to a smaller
nominal capacity range unit.
It made possible due to the ability of inverters to reach a much higher capacity level
(indicated as Maximum Capacity) which is around 115-130% of the nominal capacity.
1.2 Main Features
INTRODUCTION
High Technology
• Sine wave DC Compressor drive.
• DC-BL-SL (DC Brush-Less Sensor less) Inverter Compressor.
