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.
9- MAINTENANCE
Clean the controller surface with a soft cloth and soap and water. Do not use
abrasive detergents, petrol, alcohol or solvents.
10- 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 sup-
plied by AKO should be used.
Between -40 ºC and +20 ºC, when the probe is extended up to 1.000 m with
minimum 0,5 mm
2
cable, deviation will be less than 0.25 ºC (probe extension
cable ref.
AKO-15586
).

Portable server without supply, to which can be copied by transferred the
parameters programmed in a powered unit. The parameters may then be
transferred again from the server to other identical powered units.
To transfer parameters, other servers are available for controllers that should
be programmed identically in high quantity without power supply.
