Electrical connection
This is where the solar circuit pump (systems with solar circuit
pump) or solar circuit pump 1 (systems with two solar circuit
pumps) are connected.
Solar circuit pump SKP1
Output connection (230 V)
Output A1 is assigned differently, subject to the selected system
configuration:
Configuration 3, 5, 7: Solar circuit pump 2
Configuration 2, 4, 6, 8, 11: Motorised valve 1
Configuration 9, 10: Three-way diverter valve 1
The output is not assigned with configuration 1.
Output A1
Output A2 is assigned differently, subject to the selected system
configuration:
Configuration 6, 8, 11: Motorised valve 2
Configuration 7: Three-way diverter valve 1
Configuration 10: Three-way diverter valve 2
The output is not assigned with configurations 1, 2, 3, 4, 5, 9.
Output A2
Output A3 is assigned differently, subject to the selected system
configuration:
Configuration 2, 3, 4, 5, 6, 7, 9, 10: DHW circulation pump
(option)
Configuration 8,11: Three-way diverter valve 1
The output is not assigned with configuration 1.
Output A3
Various functions can be assigned to output A4.
a) to switch a de-stratification pump to circulate water inside a
cylinder as part of pasteurisation
b) as thermostat function: The output will be switched if the selected
cylinder temperature is exceeded. This output can be used, for
example, to enable cylinder reheating.
Output A4
This is where the cylinder sensor (systems with solar cylinder)
or cylinder sensor 1 (systems with two solar cylinders) are
connected.
Solar sensor cylinder SFS1
(NTC)
Input connection
This is where the collector sensor (systems with one collector
array) or collector sensor of collector array 1 (systems with two
collector arrays) are connected.
Solar sensor collector SFK1
(PT1000)
Input E1 is assigned differently, subject to the selected system
configuration:
Configuration 7, 8, 10, 11: Cylinder sensor cylinder 2 (NTC)
Configuration 2: Return sensor (required) (NTC)
Configuration 1, 3, 4, 5, 6: Return sensor (required if yield calculation
has been enabled) (NTC)
The input is not assigned with configuration 9.
