1.
The status of the heating element is either ON or
OFF (shown respectively as on or oFF)
2.
The pump command is the signal to the variable speed
pump, as a % of speed (from 0 to 100%), related to the
flow rate of the domestic water side. Useful to control
the proper operation of the pump.
3.
The status of the level sensors is either Low or High
(shown respectively as Lo or Hi)
4.
The status of the valve is either Open or Closed
(shown respectively as OPn or Clo)
