Connecting a cover limit-switch
A limit switch for the swimming-pool cover can be connected to terminals 25 and 26. This
switch automatically starts ECO mode when the cover is closed.
The terminals carry a safety extra low voltage.
Level control
The built-in level control is designed both for overflow pools with spillway and for skimmer pools. The version
to be used must be specified when configuring the control unit before use: in the configuration menu select
either the option Level control - type: collect. vessel or Level control - type: skimmer pool.
Overflow pools with spillway
electrode probes must be used as the level sensors.
Thanks to the strain relief provided for the cable, these probes can be
suspended by this dedicated cable in the overflow balancing tank. It
does not matter if the individual probes touch each other. The probes are
fixed above the tank using the
probe holder.
The dedicated cables must be taken to a junction box installed by the
customer. A cable must be laid from this junction box to the control unit
(e.g. cable NYM-0 5x1.5 mm
2
). The cable must not exceed 30m in
length. The cable must not be laid alongside mains power cables.
The probes operate with safety extra low voltage (SELV).
Take special care when fitting the probes to ensure they are connected
in the correct order, because the installation will not work if the probes
are mixed up.
Use with outdoor pools
Depending on the design of the pool installation, rain water in an outdoor pool can raise the water level,
triggering the "automatic actuation" function. If you don't want this to happen, you can disconnect the
"automatic actuation ON" probe (terminal 39). All the other probes are needed for the control function to work,
so must not be omitted or bypassed.
