Fault/Cause/Remedy

Cause
Flange leaking
Pipe connections leaking
Incorrect settings on solar
control
Flow (solar-side) too low
Reversing valve defect/connected incorrectly Restore function
Control of the solar return temperature
rise poorly adjusted/defect
Flow (heating-side) too low
Gravity circulation in the solar circuit
Insulation is open / is not in contact
with the tank
Gravity circulation in the heater circuit
Remedy
Re-tighten screws
Replace seal
Re-seal
Change parameters (in particular
switch-off temperature difference)
Bleed solar circuit
Repair blockages
Change pump power
Change parameters (in particular
switch-on temperature difference)
Bleed heater circuit,
repair blockage,
increase pump power
Close / install
gravity brake
Close insulation
