Using the equipment without following the manufacturer's instructions may affect the device's safety requirements. To ensure that the device operates correctly, only probes supplied by AKO should be used. The unit must be installed in a location protected from vibrations, water and corrosive gases, where the ambient temperature does not exceed that shown in the technical data.
3.- Initial Setup 3.1.- Wizard (not available in thermometers) The Darwin range controllers have a setup wizard to configure the main parameters for the type of application chosen (see table). The other parameters will be configured according to the "Def" column in the parameter table (see section 7.1.3). For the meaning of each parameter, see section 7.1.3.
3.2.- Basic settings Type of operation (only 1-relay controllers) Specifies how the controller will control temperature (see page 10) P0=0 Direct mode, refrigeration applications P0=1 Reverse mode, heating applications Type of inputs (only 4-key controllers) Some units have 3 programmable inputs to function as probes or as digital inputs as needed. This configuration parameter is defined by P4, with the following options: P4=1: 1 probe input (S1: control probe) + 2 digital inputs (D1 and D2).

Digital input function (only 4-key controllers) The digital input function is defined by parameters P10 (D1) and P11 (D2), with the following options: P10/P11=0: Off (no function) P10/P11=1: Door contact, controls the activation/deactivation of ECO mode. (p. 11) P10/P11=2: External alarm, controls activation/deactivation of the external alarm (p. 17). P10/P11=3: Severe external alarm, controls activation/deactivation of the severe external alarm (p.
eters) 4.- Operation 4.1.- C ompressor c ontrol (not available in thermometers) NORMAL OPERATION (COOL) When the temperature in probe 1 reaches the set point value (SP) plus the probe differential (C1), COOL e 1 reaches the set the COOL relay is activated, starting the compressor and leading to a drop in temperature.
Page 11
ECO MODE (only 4-key controllers) frigeration cabinet is not used This mode saves energy during periods in which the refrigeration cabinet is not used much. While this mode is active, the screen will display the ECO icon. It is activated after a certain period (set in parameter C11) of cabinet door inactivity, for e ECO icon.
4.2.- Defrost control (not available in thermometers) On units with 1 relay, defrost can only be set by compressor shutdown. On units with 2 or 3 relays, the auxiliary relay must be set as "defrost" (P6=1), except for defrost by compressor shutdown. Max.
Page 13
Defrost termination The defrost will terminate if: -The temperature programmed in parameter 24 has been reached in probe 2 (requires an additional input for the second probe and activating it via parameter P4). -Time set in parameter d1 has passed (maximum duration of defrost). -The H key is pressed for 5 seconds.

in the probe (E2), the fans will always run ers F2 to F5. s and parameter F5 defines the status of the gital inputs as door contact (P10 or P11=1). 4.3.- Fan control (only controllers with two or more relays) Fan control s activated only for defrost by resistors, cycle COOL...
4.5.- Pump down function (only four-relay controllers) This function prevents compressor problems caused by movement of the refrigerant, using a stop/start technique of the unit controlled by liquid solenoid, the low pressure switch and the compressor. For this feature to be active, the auxiliary relay must be set as "Pump down" (P6=4), which automatically configures digital input 1 as "low pressure switch"...
4.6.- Alarms The unit alerts users via a message on the screen, by activating a relay* or both, when the programmed parameter criteria are met. Max/Min Temperature Alarm Shows the AH or AL message when the temperature in probe 1 reaches the value set in the A1 (maximum temperature) and A2 (low temperature) parameters.

Models with communication capabilities (see table on page 6) have an RS485 (MODBUS) data connection port, which allows users to manage them remotely via a PC with the AKO-5004 programme or an AKO-5005 server. A different address must be assigned to each unit on the same network. This address is defined by parameter P5.
7.- Parameter setup Through the programming menu users can set different parameters to adjust the operation of the controller to the needs of their installation. 7.1.- Programming Menu To change the set point, press the SET button for 5 seconds, or until the "SP" is displayed on the screen (not available in thermometers).
7.1.2.- Changing the operating parameters Press the SET button for 10 seconds or until "PrG" appears on the screen. After 20 seconds with no key being pressed, the equipment will return to the previous level. If you are on level 3, the changes will not be saved.
