8.13 Displaying and setting cascade parameters
The parameters for
Sime ALU HE
boilers in a cascade can be
displayed and set in the same way as with single boilers (see “
Parameter setting and display” and “List of parameters”).
m
WARNINGS
For the cascade to function correctly, the external
sensor (SE) must be installed.
8.13.1 Routing the cascading boilers
m
CAUTION
Before changing “PAR 15” (routing the cascade), the
boilers in the cascade must be set to WINTER mode
n .
On each boiler in the cascade, “PAR 15” must be set as follows:
–
"0"
to identify the master boiler
–
"1"
to identify slave boiler no. 1
– "2" to identify slave boiler no. 2
–
"3"
to identify slave boiler no. 3
–
"4"
to identify slave boiler no. 4
–
"5"
to identify slave boiler no. 5
– "6" to identify slave boiler no. 6
–
"7"
to identify slave boiler no. 7
NOTE: Avoid labelling the slave boilers with the same number.
8.13.2 CASCADE parameters for the master boiler
After setting PAR 15 on the master boiler, and where there are
more than two boilers in the cascade, access the CASCADE
parameters on the master boiler (identified by PAR A plus a
number as shown in the table) and configure parameter PAR A1.
To access the CASCADE parameters:
– press buttons L and M (~ 2s) at the same time until the
parameter menu shows
– press buttons L and M (~ 2s) at the same time again until
“--”
appears on the display
– to access the CASCADE parameters, enter the following
combinations of keys: Z N L M L .
– to scroll through the parameters press buttons L and M
– to change the parameter settings, press buttons Z and N
– to exit the menu and go back to the first screen, press one
of the function buttons, excluding RESET, or wait approx. 60
seconds without pressing any buttons.

8.14 Fault / malfunction codes
Every boiler in the cascade manages its own faults as described
in “Fault / malfunction codes”.
The faults that generate a lockout in a specific boiler are reset
by pressing the RESET button on the relevant boiler.
A lockout in the master boiler is reset either by pressing the
RESET button or from a remote device.
For the master and slave no. 1 boilers, specific faults can be
checked for as shown in the table:
Type No. Description
ALL 31 Cascade delivery probe (SMC) fault
ALL 35 Communication fault with RS485 boards
ALL 36 Number of boilers connected in cascade fault
ALL 70 Cascade stop general fault
ALL 71 General fault with a boiler in the cascade
