1 - Technical features

• Easy to use: the four buttons, the easy-to-read menu structure and the preinstalled application solutions guarantee
optimal usability.
• Simple installation: the 16 A relay means heavy loads can be connected directly without having to use an intermediate
relay: compressors up to 2 HP on the basis of the power factor and efficiency of the motor (over 0.65 at 230 V and over 0.85
at 115 V). A vast range of compatible sensor types and screw terminals guarantee highly flexible installation.
• Unit protection: special software functions, protecting the compressor from voltage fluctuations or high condensation
temperature, to guarantee optimal unit performance.
• Energy efficiency: defrosting on request, day/night mode and intelligent evaporator fan management guarantee
maximum energy efficiency.
