Troubleshooting

00 shows on the remote controller
00 shows when the MIM control box is first powered up it means the MIM PCB has activated but no
outdoor unit can be seen. Check the F1 F2 wiring is ok between the outdoor and indoor unit and
check the outdoor unit has power.
01 shows on the remote controller
01 means that the remote controller has power and it can see the outdoor unit too, this is good, in a
few seconds this will disappear.
E911 low flow alarm
If your flow rate is good (see above) but you see an E911 low flow alarm you need to test your flow
switch.
E911 is not a fault, it's a warning, it stops the unit because the water is moving too slowly through the
system. With the pump running test the flow rate see page 20 and 22
If your flow rate is less than recommended you need to turn up the pumps, open any valves that might
be closed, clean filters and get rid of any air. The unit MUST have he correct flow rate before it will try
to run. Also check the flow switch is in the right way round (there is an arrow on it) and its plugged in.
Cold Weather Protection, my unit won't start
Check the flow temperature see page 20. If this is below 10°C the compressor will not start.
If you are commissioning the unit from cold
You must warm up the water to get the unit to run, the easiest way to do this is to add a cylinder and
use the immersion to warm up the cylinder first, the warm water from the cylinder will preheat the
heat pump and it will start to operate.
