Description
An interruption was detected at the
displayed sensor input (in this case:
sensor input 2).
A short-circuit was detected at the
displayed sensor input (in this case:
sensor input 2).
The controller has detected a flow
rate fault in the primary or secondary
circuit. A permanently high tem-
perature difference exists between
the heat source and loading target.
Primary and secondary circuit pumps
are flashing. Possible causes:
• Air in system
• The isolating valve is closed.
• The pump is faulty.
The controller has detected faulty
operation of the system. This is prob-
ably caused by swapped collector
connections.
A short-circuit exists at output R1, the
pump connected to output R1 flashes.
Possible causes:
• The pump is faulty.
• Wiring fault
Check the solar circuit for air.
Check the isolating valve.
Clean the solar circuit (flush).
Adjust temperature difference in
the Parameters settings menu.
Check the position of the collector
sensor and correct if necessary.
Remedy
Check the cable and
sensor connected to
the sensor input.
Check the cable and
sensor connected to
the sensor input.
• Bleed air from the
system.
• Check the isolat-
ing valve.
• Check the pump.
Check the collector
connections.
• Check the pump.
• Check the wiring
to R1.
