will request the following basic adjustments:
• Menu language
• Temperature unit
• Volume unit
• Pressure unit
• Energy unit
• Auto DST
• Time
• Date
• Selection: System or Scheme
• Scheme number (if selection = Scheme)
• Solar system (if selection = System)
• Hydraulic variant (if selection = System)
At the end of the commissioning menu, a security enquiry follows. If the security
enquiry is conrmed, the adjustments are saved.
For further information about the commissioning menu see page 14.
2. Registering sensors
If a owmeter, a ow switch, a FlowRotor and / or a Grundfos Direct SensorTM are

5.1 Basic systems and hydraulic variants
System
The controller is pre-programmed for 4 basic systems. The selection depends on
the number of heat sources (collector  elds) and heat sinks (stores, pool). Factory
setting is system 1.
A solar system with store loading in layers is
implemented as a 2-store system
(store top = store 1; store bottom = store 2).
System 0: no solar system
System 1: 1 collector  eld - 1 store
System 2: East / west collectors - 1 store
System 3: 1 collector  eld - 2 store
System 4: East / west collectors - 2 store
The selection of the basic solar system is one of the most important adjustments
and is thus requested already in the commissioning menu.
First, the basic system is adjusted by means of the number of stores and collectors
 elds, then the hydraulic variant.
The selected system is visualised by the corresponding number of store and collec-
tor symbols.The  gure to the left shows system 4 which consists of 2 stores and 2
collector  elds (“east- / west collectors”).
Variant
The hydraulic variant refers to the different actuators that are to be controlled.
They are visualised on the display by means of symbols, when the variant is selected.
The upper symbol indicates the actuator belonging to the collector  elds, the lower
one the actuators belonging to the stores.
The exemplary  gure shows the display indicated when system 4, variant 1 has
been selected. In this case, each collector  eld has a pump, the stores are loaded by
means of valve logic.
For each variant, the controller allocates the corresponding relays and sensors.The
allocations of the most important combinations are shown in chap. 5.2.
