CONTROLLING THE BOARD VIA NETWORK
The variables shown in the list are only some of the total variables available.
DO NOT CONFIGURE VA-RIABLES THAT ARE NOT SHOWN IN THE TABLE,
OTHERWISE THE OPERATION OF THE HUMIDIFIER MAY BE AFFECTED. NOTE:
The software release is made up of 4 digits and is shown on the sticker on
the back of the controller. For example, the code "1.080" indicates: hardware
release "1.0" and software release "8.0". Make sure the correct network address
has been set for parameter C3 (internal variable I13) before setting the
address of the CPY controllers. Each humidifi er is confi gured by default with
address 1, two units cannot have the same address.

3
param. d9: rated capacity in kg/h (see the table of parameters)

param. d7: maximum production in kg/h (see the table of parameters)
15
param. d3: instant steam fl ow-rate in kg/h; read-only. Format "#### = #### (100 = 100 kg/h)".
