3.2 Basic systems and hydronic variations
A solar system with a vertical tank charging is imple-
mented as a 2-tank system (tank top = tank 1; tank
bottom = tank 2).
System 1: 1 collector field - 1 tank
System 2: east/west collectors - 1 tank
System 3: 1 collector field - 2 tanks
System 4: east/west collectors - 2 tanks
System 5: 1 collector field - 3 tanks
System 6: east/west collectors - 3 tanks
System 7: 1 collector field - 4 tanks
3. Commissioning
The controller is partially freely programmable. For special
applications, the relays and the corresponding sensors are
assigned in steps.
7 basic systems with different hydronic variations each are
pre-programmed.
1. Adjust the basic system; sensors and relays will be allo-
cated automatically (see 3.2 and 4.1).
2. Activate the internal heating circuit module if needed
(see 4.2.1). If the corresponding relays are intended for
other purposes, connect the external heating module(s)
HKM.
3. Activate further options (bypass, external heat exchanger
etc. see 4.1 and 4.2.)
4. Select free function blocks for further applications (re-
turn preheating, use of further heat sources; see 3.3 and
4.2.)
5. After every step, carry out special adjustments (switching
conditions and limits; see 4.1 and 4.2).
6. A heat quantity measurement function (see 4.3) and other
functions such as reports or chimney sweeper can be
activated.
Alternatively, one of the 30 pre-programmed system layouts
can be selected (see 4.1).
The controller can be adjusted in steps (see 3.4.). All func-
tions, options and menu items are described in detail in
chapter 4.
3.1 Commissioning the controller
The controller is pre-programmed for 7 basic systems. The
selection depends on the number of heat sources (colle-
ctor fields) and heat sinks (tanks, pool). Factory setting is
system 1.
