1. INTRODUCTION
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
High Technology
•Sine wave DC Compressor drive.
•DC-BL-SL (DC Brush-Less Sensor less) Inverter Compressor.
•DC-BL Inverter Outdoor Fan.
•Fuzzy Logic Adaptive Control.
System Features
•Variable cooling and heating capacity from 30% to 115% (of rated capacity).
•High COP “A-B” class energy rating (Most units).
•Low noise levels.
•Pre-charged system up to 30m.
•Tubing up to 70m length / 30m height difference.
•Networking connectivity.
•Current limitation setting for circuit breaker size reduction (if required).
•Dry contact inputs:
Standby.
Night mode (for silent operation in cooling).
 Power Shedding (to control maximum power consumption).
•Dry contact output:
Alarm
 Base Heater
Crank Case Heater
