Failures with error message
1. Some system failure modes can be recognised by the solar
differential temperature controller and will be indicated by an
error message on the controller display. Refer to the table
below for details of possible errors and suggested measures to
rectify.
NOTE:
These error messages wil automatically reset when
the fault has been rectified. In the case of the circulation error
this may take a few minutes to clear once normal flow has
resumed.
Error representation on display Possible reasons
Measures
• Sensor wire broken
• Check wire
• Sensor defect
• Check sensor resistance, if necessary exchange sensor
• Sensor missing
• Check parameter settings and sensor installation
requirements
• Short circuit in sensor wire
• Check wire
• Sensor defect
• Check sensor resistance, if necessary exchange sensor
• Error in pump connection
• Check cabling
• Pump defect
• Exchange pump
• Air in the system
• Check the float of the flow meter moves
when the system runs (if visible)
• Connection with flow
• Check wire
