1.- Presentation
PROPlus 3PH is the global electronic solution to manage positive and negative cold room stores, in combination with:
ŸStandard condensing units
ŸStreamlined condensing units
ŸOr as a service panel in decentralised systems.
It has a high IP65 degree of protection for installation in damp environments. It is easy to install thanks to its new
connection strip and intuitive menus with help texts that make programming easier by using its backlit LCD display.
1.1.- Maintenance
Clean the surface of the unit with a soft cloth, water and detergent. Do not use abrasive detergents, petrol, white
spirits or solvents.
Units that include rechargeable electrical accumulators:
This unit includes accumulators that should be replaced when the unit's battery life is under the duration
assigned in its specifications. At the end of the useful life of the unit, the accumulators should be taken to a
selective waste collection centre or returned to the manufacturer.
1.2.- Cautions
Using the unit not observing the manufacturer's instructions may alter the appliance's safety requirements. Only probes
supplied by AKO should be used for the it to operate correctly.
2
From –40 ºC to +20 ºC, if the NTC probe is extended to 1000 m with at least 0.5 mm cable, the maximum deviation
will be 0.25 ºC (cable for probe extension ref. AKO-15586).
IMPORTANT:
ŸThe function of each probe depends on the "probe setting" parameter (See probe configuration on page 14).
ŸThe AUXILIARY relay is programmable, and its operations depends on the configuration (See page 26).
ŸThe function of the digital inputs depends on the configuration (See page 25).
ŸThe recommended currents and powers are the maximum working currents and powers.

When the temperature in probe 1 reaches the set
point value (SP) plus the probe's differential, the
compressor/solenoid* is activated making the
temperature drop. When the set point value (SP) is
reached, the compressor/solenoid* stops.

NORMAL OPERATION
CONTROL BY THERMOSTAT
Temperature is controlled by an external thermostat instead of probe 1, and to do so one of the digital inputs must be
configured as "Thermostat control".
This configuration cancels the probe inputs, and therefore temperatures will not be displayed nor will the functions
associated with them be carried out (temperature, alarms, HACCP logging, etc.).
CONTINUOUS CYCLE MODE
Use this function to cool the cold rooms before loading products.
It is activate pressing the O key for 5 seconds, the display shows the % icon while this mode is active.
ENERGY SAVING MODE
It allows energy saving in the periods of low activity of the cold room, and in this way reduces the installation's
electricity consumption. The display will show the Z icon when this mode is active.
It is activated using time programming, using the Energy saving start parameter on the u menu with the options:
ŸDay: Defines the days this mode will be activated on;
žDeact.: It will never be activated.
žMonday/Tuesday/Wednesday/Thurdsay/Friday/Saturday/Sunday: It will only activate on the chosen
day.
žMon-Sun: It will activate everyday (from Monday to Sunday).
žMon-Sat: It will activate everyday except Sunday.
žMon-Fri: It will activate everyday except Saturday and Sunday.
žSat-Sun: It will only activate on Saturday and Sunday.
ŸHour: It times the energy saving mode start hour.
ŸMinute: It times the energy saving mode start minute.
When this mode is activated, the compressor / sole-
noid* starts to operate continuously, and without ta-
king the set point into account, until the time confi-
gured in the continuous cycle duration parameter
elapses, or until the O key is pressed again for 5 seconds.
The unit will immediately return to normal operation.

The Set point energy saving parameter defines what the set point will be when this mode is active and the
Energy saving duration parameter defines the duration of this mode in hours. It never activates if it is
configured at 0.
This mode may optionally be activated and deactivated whenever you want using the external button connected to one
of the digital inputs, and to do so the corresponding input should be configured as "Remote energy saving”.
COMPRESSOR PROTECTION DELAY (according to model)
This protects the compressor, preventing continuous stops and start-ups in certain exceptional cases.
The Comrpessor Protection parameter allows choosing between 2 types of delay:
OFF-ON: Minimum time the compressor should stay stopped before each start-up.
ON: Delay time as from when the compressor should activate until it does activate.
The Protection delay time parameter defines the time of the previous parameter.
FUNCIONAMIENTO EN CASO DE FALLO EN SONDA 1
If probe 1 fails (failure, disconnection, etc. ), the compressor/solenoid* operates according to the times
programmed in the following parameters:
Compresor ON error s1: Compressor/solenoid* time in operation in the event of fault in probe 1.
Compresor OFF error s1: Compressor/solenoid* time stopped in the event of fault in probe 1.
SET POINT LOCKINGS
Using the Set Point upper limit and Set Point lower limit parameters, it is possible to set a top and bottom limit for
the Set point (SP) parameter, which prevents being able to set a set point that is too low or too high that might
damage the installation or the stored product.
STOP COMPRESSOR WHEN THE DOOR IS OPENED
This defines if the compressor/solenoid* will be stopped whenever the cold room's door is opened. To do so, one of
the digital inputs should be configured as "door contact" (See page 25).
If the door stays open longer than the value programmed in the Inact. with door open parameter, the
compressor/solenoid* will return to normal operation (See page 25).

Defrost start
Defrost will start if:
ŸThe time programmed in the Defrost frequency parameter has passed since the start of the last defrost.
The parameter Defrost mode defines how this time is counted:
žFrequency: Total time passed between defrost starts.
žCompressor sum: Total time of the compressor/solenoid* operating between defrost starts.
žReal Time Clock: Defrost starts when one of the times programmed in the Defrost 1 to 8 on the
u menu is reached. (The defrost frequency is not taken into account).
ŸWe press the N key for 5 seconds.
End of defrost
The defrost stops if:
ŸThe temperature programmed in the Defrost final temperature has been reached in probe 2 (this requires
having a defrost probe connected to S2). In the event of probe 2 failure, defrosting will be complete once the
maximum time has elapsed (d1).
ŸThe time configured in the Defrost duration has passed (maximum defrost duration). The I icon is shown on
the display if the Signals end defrost time parameter is configured in “Yes”.
ŸWe press the N key for 5 seconds.
REMARK: If the Defrost duration is configured to 0, no defrosts are carried out.

Drip time after defrost
This is establishing using the Drip time parameter of the H menu and defines the time added at the end of the defrost
to allow removing any water left in the evaporator.
During this time, the compressor/solenoid* and fans will be stopped (except if the defrost is by air).
Message displayed during defrost
This is established using the Defrost message parameter, and you can choose between displaying the real
temperature captured by probe 1, show the temperature capture by probe 1 at the start of the defrost, or display the
DEFROST message.
The Message duration parameter defines how long this message is displayed, after the drip time and start up delay of
the fans (See page 19).
Other parameters
Using the Defrost at Start-up parameter, you can configure if the unit carries out or not a defrost when it receives
power (first start up or after a fault in the power supply).
If the "YES" option is chosen, defrost starts after the time defined in the Defrost delay at Start-up parameter on the
H menu.
Remote defrost
This function allows activating the defrost of the unit using an external button, connecting it to one of the digital inputs
that must be configured as "remote defrost”.
*In the panels AKO-15658 / 15659, the liquid solenoid is controlled instead of the compressor.

9.3.- Fan control
Fan control is carried out using probe 2 and taking the following parameters into account:
ŸFan stop temperature: It defines the temperature at which the fans stop.
ŸFans differential s2: It defines the temperature differential of probe 2 (evaporator).
ŸStop when compressor OFF?: It defines if the fans stop in each compressor stop.
ŸFans state during defrost: It defines the status of the fans during the defrost.
ŸFans delay after defrost: If configures the time that passes before starting the fans up, at the end of a defrost.
ŸStop when opening door: It defines if the fans are stopped when the cold room's door is opened (this requires
having configured one of the digital inputs as door contact).
If the door stays open longer than the value programmed in the Inact. with door open parameter, the fans
return to normal operation.
If probe 2 is not connected or an error in the probe is detected, the fans will always be operating without taking into
account the temperature related parameters, but taking the rest of the parameters into account.
9.4.- Light control
The unit has an additional relay to control the cold room's lights.
Just press the ? key to turn the lights on/off.
This function is even active when the unit is in Stand-by.
Light timing
The unit activates the lights whenever the cold room's door is detected to have been opened, and turns them off after
the time programmed in the Cold room light timing parameter, even though the door stays open. If time is
configured at “0”, timing does not start.
One of the digital inputs should be configured as "Door contact”.
