Complying with and enforcing the regulations applying to installations where our products are destined to be used is the responsibility of the installer and the customer. AKO Electromecànica accepts no liability for damage which may occur due to failure to comply with these regulations. -
Page 3: Presentation
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. Between -40 ºC and +20 ºC, if the NTC probe is extended up to 1,000 m with minimum 0.5 mm² wire, the maximum deviation will be 0.25 ºC (Wire for probe extension ref. -
Page 4: Recommendations
1763H532 Ed.02 3.- Recommendations Disconnect the voltage before carrying out any operations inside the electrical panel. All wiring should be according to current standards and should be carried out by authorised staff. Only carry out the wiring foreseen in the wiring diagrams. -

Page 8: Quick Configuration
1763H532 Ed.02 6.- Quick configuration The quick configuration menu allows the unit to be configured for the most common applications. Press the for 5 seconds to access it. If the access code is activated, a 2 digit code is requested (See p. 15), if the code entered is not correct the unit will not enter programming. -
Page 9: Operation
1763H532 Ed.02 7.- Operation 7.1.- Compressor control probe 1 reaches the set NORMAL OPERATION When the temperature in probe 1 reaches the set differential of the probe point value (SP) plus the differential of the probe COMP. (C1), the compressor and solenoid are activated and the temperature drops. - Page 10 1763H532 Ed.02 COMPRESSOR PROTECTION DELAY There are three types of delay, selectable by parameter C4, to protect the compressor. These delays prevent continuous compressor starts and stops due to sudden changes in temperature. OFF-ON (C4=0): Minimum compressor OFF time before each start-up. OFF-ON / ON-OFF (C4=1): Minimum time during which the compressor will remain ON and OFF in every cycle.

1763H532 Ed.02 Other parameters Parameter d5 allows users to specify if the unit will (d5=1) or will not (d5=0) defrost when powered up (initial start-up or after a power failure). In case of choosing option YES (d5=1), the defrost will start after the delay time specified in d6. -
Page 13: Pump Down Function
1763H532 Ed.02 7.5.- Pump down function 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 function to be active, it must be configured in parameter P26= 1. PARO When the temperature in probe 1 reaches the set point (SP) value, the liquid solenoid closes. -
Page 14: Alarms
1763H532 Ed.02 7.6.- Alarms The unit warns the user by displaying an on-screen message when the programmed 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) or A2 (low temperature) parameters. -
Page 15: Access Code (Password)
1763H532 Ed.02 Pump down malfunction error (Start up) Displays the LP message if a malfunction is detected when the installation is started up using the pump down manoeuvre. (See page 13). Compressor safety chain alarm The ASC message is displayed if any component in the compressor's safety chain is triggered (compressor motor guard, thermistors or high pressure controller). -
Page 16: Parameter Transfer
1763H532 Ed.02 8.- Parameter transfer This function allows transferring the programmed parameters from one device to others, using the AKO-D14918 programming key. This will save a lot of time when configuring similar devices. Transfer parameters from the equipment to the key Connect the programming key in the parameter server connector. -
