Warnings
-Using the unit without observing the manufacturer's instructions may alter the appliance's safety
requirements. Only probes supplied by AKO should be used for the unit to operate correctly.
-From -40 °C to +20 °C, if the NTC probe is extended to 1000 m with at least 0.5 mm cable, the maximum
deviation will be 0.25 °C (Cable for probe extension ref. AKO-15586. Connect the welded wire fabric to
earth at one end only).
-Only NTC probes supplied by AKO should be used for the appliance to operate correctly.
-It should be installed in a place protected from vibrations, water and corrosive gases, where the ambient
temperature does not exceed the value indicated in the technical data.
-For the reading to be correct, the probe should be used in a place without heat influences apart from the
temperature you want to measure or control.
-IP65 protection degree is only valid with the protection cover closed.
-IP65 protection degree is only valid if the cables enter the device using a tube for electric conductions + gland
with IP65 or above. The size of the glands should be suitable for the diameter of the tube used.
-Do not spray the unit directly with high-pressure hoses, as this could cause damage.
IMPORTANT:
The AUXILIARY relays are programmable, and their operation depends on the configuration.

Wiring
Always disconnect the power supply to do the wiring.
The probes and their cables should NEVER be installed in a conduit together with power, control or power
supply cables.
For disconnection, the power supply circuit must be equipped with a switch of at least 2 A, 230 V, located near
the device. The power supply cable will be H05VV-F or NYM 1x16/3. The section to be used will depend on the
local standard in force, but must never be less than 2.5 mm .
Cables for relay or contactor outputs should have a section of 2.5 mm , allow working temperatures equal to or over
70 °C and be installed with as few bends as possible.
The 120/230 V~ wiring must be kept clear of any other external element.
The wiring to be done depends on the type of installation. Use the appropriate diagram based on
the option selected in the wizard. Check the available options on the attached diagram sheet.
The AKO-16523D model has a contactor which allows for the connection of three-phase defrost resistors, three-
phase compressor or three-phase fans according to installation requirements. Check how to connect it in the
attached diagram sheet.
Maintenance
Clean the surface of the unit with a soft cloth, water and soap.
Do not use abrasive detergents, petrol, alcohol or solvents, as this might damage the unit.
