Failures with error message

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.

Error representation on display Possible reasons

Measures

flashing

• Sensor wire broken

• Check wire

• Sensor defect

• Check sensor resistance, if necessary exchange sensor

flashing

• 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
