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.

3 - Quick-start conﬁguration

• 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 “o 61”

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).

App Description App 0 None (no preset application) App 1 Medium temperature ventilated ref. units (2 – 6 °C), with timed natural defrosting App 2 Medium temperature ventilated ref. units (0 – 4 °C), with timed electric defrosting App 3 Low temperature ventilated ref. units (-26 – -20 °C), with timed electric defrosting App 4 App 5 App 6 None (no preset application) with simpliﬁed parameters list

Medium temperature ventilated ref. units (0 – 4 °C), with timed electric defrosting (on the basis of the temperature) Low temperature ventilated ref. units (-26 – -20 °C), with timed electric defrosting (on the basis of the temperature)

• 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.

• STEP 5: Conﬁgure output DO4 “o36”

The display automatically shows the parameter “o36” to conﬁgure the output “DO4”. Select light (“Lig”) or alarm (“ALA”) on the basis of the application and press SET to conﬁrm. The display is reset in normal display mode with the control on.

• Press SET for three seconds to open the parameter groups.

• Select the “cFg” menu and press SET to open. The ﬁrst menu “r12 ” (main switch) is displayed.

• Set the main switch to OFF (r12=0) to change the preinstalled application.

• Press UP/DOWN to scroll through the parameters list.

• Conﬁgure the parameter “o61” to select a preinstalled application:

- Press SET to open the parameter “o61”.

- Press UP/DOWN to select an application (AP0= no application).

- Press SET to conﬁrm; “o61” is displayed.

• Continue to set the following parameters (sensor type “o06” and conﬁguration “O36” DO4) in the “cFg” menu.
