Parameters
Before commissioning the cascade installation, a number of parameters has to be changed.
These parameters can be programmed on the unit itself, without the use of a computer.
Changes in parameter may only be carried out by a skilled commissioning/service engineer, who has had
specific training for setting up the S-CB
+
/ S-CB PX 120 range boilers. He will be able to check whether the
installation functions correctly after the parameter change has been done.
For programming,
all parameters
of the boilers one needs to have an interface cable for connecting the
laptop to the boiler control and a laptop with the appropriate S-CB
+
software. This software is used for
programming but also shows all measured temperatures and cascade behaviour during operation and
service/fault history.

Parameter settings for cascaded boilers
Before programming the cascaded boilers, make sure that all boilers are connected (wire) with each other.
Use connection 17 and 18 of each boiler on S-CB+ boilers – Use connection 15 and 16 on S-CB PX 120.
Remind
: Do not alternate these connections, so always connect 17 to 17 and 18 to 18 on the S-CB+ version
and 15 to 15 and 16 to 16 on the PX 120.
After connection, every boiler must be programmed as follows:
