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.
Cautions
-Using the unit not observing the manufacturer's instructions may alter the appliance safety requirements. Only
probes supplied by AKO should be used for the unit to operate correctly.
-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).
-Only NTC probes supplied by AKO should be used for the appliance to operate correctly.
-The AKO-15643 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.
-Always disconnect the power supply to do the wiring. The power supply circuit should have a main switch and
residual current protection outside the panel (according to 2 2 R.E.B.T.). The power supply cable will be H05VV-F
2
2x2.5 mm or H05V-K 2x2.5 mm .
Battery
You should connect the battery cable (1) and plate connector (2) before
installing the unit.
