which parameters programmed in a powered controller
can be copied by transfer. Parameters can be transferred
99
again from the server to other identical powered con-
trollers.
To transfer parameters, other servers are available for
controllers that should be programmed identically in

8- Maintenance
1
Clean the controller surface with a soft cloth, soap and water. Do not use abrasive deter-
99
gents, petrol, alcohol or solvents.
9- Warnings
The use of the unit without observing the manufacturer's instructions may alter its safety
qualification.
To ensure correct operation of the apparatus, only NTC type probes supplied by AKO should
be used.
1
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).

(*) The intensity specified for each relay is its maximum individual value; if more
than one is connected, the intensity of the addition (COMPRESSOR + DEFROST
99
+ FAN) must not exceed the total maximum intensity specified in the rating
plate.
