Reason why the unit
does not run.
[001] : Water inlet temperature is too high
→
If possible decrease water inlet temperature
[002] : Calculated water outlet temperature is too high
→
If possible increase flow rate
[004] : Inlet and Outlet temperature are reversed
→
Check the pipes and re-install it correctly
