The two probe inputs can be interrelated with the two relay outputs for the thermometer,
thermostat and the timing functions in cold and heat applications.
CONFIGURATION
allows that some parameters are
ADJUSTABLE
or not by the
USER
so
that he or she has the exclusive information and adjustment that the device’s use requires.
The functions of the front part keys as well as the display of temperatures can be modified,
while the configuration with a password can be blocked.
Warnings
The use of the unit different to the manufacturer’s instructions voids the safety qualification.
To ensure correct operation of the apparatus, only NTC type probes supplied by AKO should
be used. Between -40 ºC and +20 ºC, when the probe is extended up to 1.000m with
2
minimum 0,5mm cable, deviation will be less than 0.25 ºC (probe extension cable ref.
AKO-15586
)

The controller must be installed in a place protected from vibrations, water and corrosive
gases, and where the ambient temperature does not surpass the values specified in the
technical data.
In order for the panel mounting units to be suitable having IP65 protection, the gasket
should be installed properly between the apparatus and the perimeter of the panel cut-out
where it is to be fitted.
In order to give a correct reading, the probe has to be installed in a
place without heat influences other than the temperature that is
to be measured or controlled.
To fix the unit, place the
fasteners 1 over the sliders 2
as shown in the figure. Move
the fasteners in the direction
of the arrow. By pressing tab 3
the fasteners may be moved
in the opposite direction of
the arrow.
See diagram in the unit rating plate.
The probe and its lead shoud
NEVER
be installed in ducting along with power, control or
power supply wiring.
The power supply circuit should be connected with a minimum 2A, 230V, switch located
close to the unit.

connecting wires for relays contacts must be between 1mm2 and 2,5mm
UP key:
By pressing this key, the temperature in probe 2 is displayed.
By pressing it during 5 seconds, the R2 SET POINT is displayed.
In programming, it increases the value being displayed.
By default, the configuration of this key is factory-set for the preceding actions. However, it
can be configured according to the options of parameters 42, 43.
Q
DOWN key:
By pressing this key during 5 seconds, the R1 SET POINT is displayed.
In programming, it decreases the value being displayed.
By default, the configuration of this key is factory-set for the preceding functions. However,
it can be configured according to the options of parameters 44, 45.

Pressing these keys during 10 seconds accesses to the configuration of the controller
parameters.
Pressing these keys once accesses to the adjustment of the user’s parameters.
By default, the configuration of these keys is factory-set for the preceding function,
however, they can be configured according to the options of parameter 46.
ºC:
Permanent: Temperature display in ºC. Flashing, parameters programming phase.
ºF:
Temperature display in ºF.
R1/R2:
Relay R1/R2 activated.
It should only be programmed or modified by personnel who are fully conversant with the
operation and possibilities of the equipment.
Press the CONFIGURE OR ADJUST keys for 10 seconds. The LED “ºC” will be flashing to
indicate programming phase and the first parameter “01” will appear on the display.
Pressing the
N
key accesses the next parameter and the
Q
key will produce a return to the
previous one.
Pressing DISPLAY VALUE key in the last display EP the controller will return to the current
temperature display status and the LED “ºC” will stop flashing.
In order to display the current value of any parameter, select the desired parameter and
press the DISPLAY VALUE keys. Once it is displayed, it can be modified by pressing the
N
or
Q
keys.
Pressing the ACCEPT THE NEW keys sets the new value. When this operation is performed,
the programming returns to Level 1 (parameters).
ADJUSTMENT:
Pressing once the CONFIGURE OR ADJUST keys accesses the user’s
parameters adjustment. The proceeding is the same as for the configuration and access is
only possible to the parameters defined as adjustable by the user in the configuration. In
order to access the parameters the parameter 39 parameter should be configured.
REMARK:
If no key is pressed for 25 seconds in any of the previous steps, the controller will
automatically return to the current temperature display status without modifying any of the
parameters values.
REMARK:
When the time parameters are modified, the new values are applied once the
current cycle is completed. In order for it to have an immediate effect, switch the controller
off and then on again.
