14.1 Single/ multiple pump system
Set up the DIP S12-2 according to the system type.
Single water pump
The retaining valve is not necessary with this configuration.
The pump control is only activated on the master unit.
Fig. 101 Single water pumps
Multiple water pumps
A retaining valve for each unit is necessary with this configuration.
Pump control is activated on each unit.
Fig. 102 Multiple water pumps
Set multiple configuration on the units
Set the correct date and time on each unit before connecting them to the
network.
Set multiple configuration on each unit.
SW12-2: ON unit on modular configuration (or enabling DHW menu);
OFF single unit.
The modular configuration is made up of two networks: the controller
network and the unit network (main keypads).
Each network can have max.16 addresses (0 to 15) and must be
addressed separately.
Each network has its own master, which must have address = 0.
If some of the slave units do not have the DHW option:
• Configure a unit without a DHW option as the master
• Assign the higher addresses to the slave units equipped with DHW
option

Unit addressing
Addressing is carried out through encoder ENC4 on the back of the
keypad.
The address corresponds to the number on the encoder and it is shown
on the display DSP1.
Fig. 104
Example:
• MASTER: address = 0 encoder = 0
• SLAVE 1: address = 1 encoder = 1
• SLAVE 15: address = 15 encoder = F
