4 System descriptions
The heating controller is designed to control
five different system types which the device
differentiates by means of a system code
number. The system code number is deter-
mined on the configuration level under ‘Anl’.
Factory setting is 1. How to change the sys-
tem code number is described in chapter
3.3.2. The following table lists the basic dif-
ferences between the system types.
On the following pages, you will find a gen-
eral introduction to each system type. In the
diagrams, all safety equipment that may be
required is represented by dot-dash lines.
If a temperature controller (TC) or a safety
temperature monitor (STM) or an additional
pressure limiter (PL) is required, you must use
a control valve with safety function acc. to
DIN 32730.
On the side of the heater, you are required
to install a TC/STM combination, if required
by DIN 4747 Part 1.
A pressure limiter (PL) must be installed, if
DIN 4751 requires it.
You are required to install a TC/STM combi-
nation in a primary drinking water heating
circuit, if required by DIN 4753.
