MAINTENANCE
Water flows out of the temperature/pressure
relief valve (only during heating up).
There is dirt on the valve seat of the
temperature/pressure relief valve.
Check the seat of the temperature/pressure
relief valve and suppress the fault.
The temperature control system for
the gas-fired boiler is faulty.
If water is only escaping when being heated up
by the gas-fired boiler, check the temperature
control system of the gas-fired boiler.
Check whether the 2-way valve switches to the
heating position when the cylinder temperature
is reached.
Cylinder sensor is faulty. Check the cylinder sensor and corresponding
safety thermostat, replace the cylinder sensor if
necessary, and suppress the safety thermostat
fault.
The 2-way valve is faulty. Check the function of the 2-way valve and
replace if necessary.
Temperature and pressure relief valve
is faulty.
If water is only escaping when being heated up
by the electric immersion heater, replace the
temperature/pressure relief valve.
Electric immersion heater is faulty. Check the temperature sensor of the electric
immersion heater and the corresponding safety
thermostat and replace the electric immersion
heater if necessary.
Only connection wiring diagram 6: The safety
thermostat for the reheating circuit actuated at
80 ºC, thus causing the 2-way motorised valve to
close the supply line to the cylinder.
The cylinder has been overheated by
the solar circuit.
Set the maximum cylinder temperature (MAXT
1) on the solar controller to a maximum
temperature of 70 o C.
Use the fuses to deenergise the cylinder
thermostat.
Unscrew the cover cap of the reset button for the
safety thermostat (TCO) for the reheating circuit.
Press the reheating circuit TCO button to
suppress the TCO fault. Mount the cover cap.
Switch on the cylinder thermostat using the
fuses.
