6.2 Control water heater
6.3 Solar control
Via the BMS Interface, the state of the water heater and the solar control can be read out
separately. The actual state of the control of the water heater can be found on parameter
7. When a solar control is present, its state can be viewed on parameter 22.
The numbers that will be read out refer to certain states of the control(s). Some states
shall appear and disappear so quickly that they won’t be visible. This is no problem.
In the table beneath, the reference to the numbers is specified:
