1 - Technical features
2 - User interface
3 - Quick-start configuration
• 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 “<” BACK for 3 seconds.
The main switch “r12” is automatically set to OFF.
• STEP 3: Select the preinstalled application “o61”
The display automatically shows the application selection parameter “o61”.
Press SET to select the preinstalled application.
The display shows the default value (for example “AP0”, blinking).
Select the type of application by pressing UP/DOWN and then SET to confirm.
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.

Safety standards
Check the input voltage is correct before connecting the instrument.
Do not expose to water or damp: only use the regulator within the design operating limits, avoiding sudden temperature
changes with high atmospheric humidity to prevent condensate forming.
Product disposal
The device (or product) must be disposed of in compliance with local waste disposal legislation.
