heater immediately as power may be being drawn from
the grid.
Setup Errors
ERROR! HEATER
NOT DETECTED
No load was detected during setup, the immersion
heater may be switched off at the isolator, or the
thermostat open because the water is hot already.
Otherwise there may be a fault with the immersion
heater.
CLAMP CURRENT
TOO LOW!
If the import power is too small during setup, this
message will be displayed. This could be because the
inverter is still switched on (after request to be switched
off), the heater thermostat is open, or the clamp is at the
wrong location. The clamp needs to 'see' the exported
power to the grid.
