12.1.6 Run mode
Menu / Heating system / Cascade / Run mode
Since the Cascade controller from KSM is the most flexible on the marked, it is needed to tell the boiler,
how we want it to communicate with the rest of the boiler in the installation.
For this function, we have to put in a “Run mode” code, explanation off the code are written below.
The code to put in, it the way this boiler shall work.
Code Description
1.
KSM boiler with automatic ignition, that start and stop when it get the command from the master.
2.
KSM boiler without ignition, that just switch to pause mode, when it get the stop command from
the master.
3.
KSM boiler type 1. , that is connected to a boiler that don’t have a PCT400 controller, but will be
controlled with a relay, it can be another brand of biomass boiler, a gas or oil boiler.
4.
KSM boiler type 2. , that is connected to a boiler that don’t have a PCT400 controller, but will be
controlled with a relay, it can be another brand of biomass boiler, a gas or oil boiler.
12.1.7 Port and IP address
Since the boiler in the Cascade chain communicate over the network, all boilers must have their own IP
address and port no. Normal the same no. as we use for the WEB Communication
The numbers that have to be set in the menu shown below, is the numbers on the next boiler in the chain.
Menu / Heating system / Cascade / Port
Menu / Heating system / Cascade / IP 1
Menu / Heating system / Cascade / IP 2
Menu / Heating system / Cascade / IP 3
Menu / Heating system / Cascade / IP 4
That means that on boiler 1 we set the IP address and port no. on boiler 2, and on boiler 2
we set the IP address and port no. on boiler 3.
If boiler 3 is the last in the chain, it gets the IP address and port no. on boiler 1
12.2 Buffer tank
If the boiler in a Cascade installation is connected to a buffer tank, all boilers need to have 2 temperature
sensors in the buffer tank, and the sensors have to be setup as normal in a single boiler installation.
When the boiler is running, it is only the Master that react at to the temperature readings from the buffer
tank, the Slave will still get the start /stop commands from the Master.
When using a buffer tank in a Cascade installation, the delay time Slave On/Off, must be much longer.
12.3 Display info
If the boiler are running in a cascade installation, some code information will be shown in the lower left
corner of the display.
This code give us information, about the different stage that the boiler can be in, a explanation is listed up
below.
1. ”S” :
The boiler is slave.
2. ”[M]H:120:
The boiler have been Master for 120 Hours
