The boiler has a unique boiler code. This, together with
other data, incl. boiler type, counter readings, etc. is stored
in a (PSU) that belongs with the boiler. If the control unit is
replaced, the counter readings remain stored in it.
It is possible to connect various control, safety and regulation systems
to the boiler. The heat output of the boiler can be controlled as follows:
4 Adjustable control: The output varies between the minimum and
maximum value on the basis of the value determined by the
controller.
4 Analogue setting : Where the heat output or the temperature is
controlled by a 0-10V signal. (Standard with Diematic iSystem -
Only possible with the SCU-05 or IF01 control board with
IniControl).
4 On/Off setting: where the heat output modulates between the
minimum and maximum value based on the flow temperature set
in the boiler.
