• 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.
• STEP 1: Startup
• STEP 2: Select quick-start configuration menu
Within 30 seconds of startup, press “

The regulator presets the parameter values on the basis of the application selected and hides any irrelevant parameters.
Tip: you can easily switch from AP0 to AP6 and therefore select the simplified parameters list by pressing the UP button
(circular list).
• STEP 4: Select the sensor type “
o06
”
The display automatically shows the sensor selection parameter “
o06
”.
Press SET to select the type of sensor.
The display shows the default value (for example “
n10
”, blinking).
Select the type of sensor by pressing UP/DOWN (n5=NTC 5 K, n10=NTC 10 K, Ptc=PTC, Pt1=Pt1000) then SET to confirm.
NOTE: all the sensors must by the same type.
