Installation: commissioning
1. Restore power to external diverter and Mixergy controller
2. Cancel and scheduled heating events/boosts from the Mixergy
controller (if active).
3. Set the PV diverter to bypass/boost and check that the immersion
is heating via the diverter.
4. Set the Mixergy controller heat source to electric and boost using
the gauge, observe that the bypass/boost function of the diverter
is switched off and the cylinder continues to heat via. the Mixergy
controller supply.
5. Set the exchanger circulator pump speed to setting II for heat
pumps, I for solar thermal.
Troubleshooting
Diverter not working correctly
If the diverter is unable to supply heat to the cylinder, perform the
following checks:
• Check that the cylinder is not entirely full of hot water (i.e. 100%
charged). If the cylinder is full of hot water, drain the cylinder
down 20-30% and repeat the commissioning steps.
•
Check that the cylinder immersion thermostat is adjusted to its
maximum set temperature.
• Check that the diverter is setup correctly according to
manufacturer's instructions.
RCD tripping
If an RCD is tripping when the cylinder is switched on, double check all
mains wiring to the PV switch, diverter and cylinder immersion.
Electrical fault
If an electrical fault of the controller is suspected or the electrical
system does not operate as expected, please contact Mixergy directly.
