Initial Checks (Non-Wireless Installation)
Once all wiring has been completed and checked the following commissioning checks should be
performed.
1.
Apply power to the control unit. The display should illuminate and a start-up message
displayed.
The “home” screen should then be displayed:
2.
Turn off the PV system at the main PV isolator.
This is to ensure that no power can be exported from the property for the next check:
3.
Verify that the bottom line of the Apollo GEM display shows “
Importing X.XKW
”
If the display shows “
Exporting X.XKW
” then the sensor clamp is positioned on the cable
facing the wrong way. Unclamp the sensor and turn it around to face the other direction.
4.
If the bottom line of the Apollo GEM display shows “
Importing X.XKW
” the PV system can
be turned back on.
Briefly press the "Boost" button to start boost mode.
This will check that:
a)
The heater is working and b) The power measuring system is working correctly.
Check That the display shows "Boost 1 ON 60 mins" and that the measured
import
power has
increased
by approximately the heater power e.g. 3KW.
(If exporting check the
export
power
decreased
by the heater power)
If Boost mode remains on and the power reading is as expected then everything is working.
Press the boost button four more times to turn off boost mode.
The system is now ready for operation.
If Boost Mode Will Not Stay On
If Boost mode starts but then ends and returns to optimising a few second later, this is because the
controller has detected that the heater is not drawing any power. Common reasons for this can be:
•
The water is already hot and the thermostat is off
•
The thermostat is set at too low a temperature
•
The thermostat is not working (failed open circuit)
•
The heating element has failed
•
The heater is not correctly wired to the controller output
