3.14 - ADJUSTMENT OF M 3000 IN
COMPLEX INSTALLATIONS
Cascade connection of several M 3000 S
The application of M 3000 S in complex installations requi-
res the designation of a main module (MASTER) and se-
condary modules (SLAVE).
SETTINGS OF THE MAIN MODULE (MASTER)
Once the settings of the (A) switches 1-2-3-4 on the main
module (MASTER) have been completed, it is necessary to
modify through the REGOLAFACILE the parameter 07 ‘’num-
ber of secondary modules connected (SLAVE)’’.
Change the value according to the number of secondary mo-
dules connected (in this case
3 ); follow the procedure for the
parameter modification described in the chapter 3.11.
SETTINGS IN SECONDARY MODULES (SLAVE)
(suitable for configurations up to 3 slave modules)
Set the switches as shown in
B - C - D .

3 ON Boiler with data communication capacity
OFFBoiler without data communication capacity

07 Hn 0 1 ÷ 13
The functionality of switch 4 depends on the position of switch 3
Switch Setting Description
3 ON Boiler with data communication capacity
4 ON Direct data connection between M3000 & boiler
OFF Data connection via PCB 00630083
Switch Setting Description
3 OFF Boiler controlled in ON/OFF mode
4 ON The boiler temperature is controlled by M3000
(Es. Caldaie in acciaio)
OFF La temperatura è controllata dalla caldaia
(es. caldaie murali).
