1 - The maximal setpoint (parameter 207) is factory set at 70. A qualified engineer can modify this value.
2 - Parameter 005 will only be accessible when parameter 004 is set on ENA.
Note
When parameter 202 is set to Off, the anode warning Ano will not be shown on the
display. Also when there is a problem with the anode protection, this warning will not be
shown. The tank protection cannot be guaranteed. The warranty will be void.
10.3
Hysteresis
The water heater does not start immediately when the water temperature is below the
temperature setpoint. To prevent that the water heater switches on and off too often,
there is a margin; the hysteresis.
The standard hysteresis is 10 °C. Thus, the water heater starts to heat up when the water
temperature is 10 °C below the temperature setpoint. Use parameter 003 to change the
hysteresis.
10.4
Error history
The control unit automatically stores data of occurred errors and failed actions of the water
heater. The error history can be used to analyse the water heater and to find the causes of
the errors and failed actions.
Use parameters 270 till 273 to read the errors. Use parameters 274 till 277 to read the
appliance history, refer to Parameters (see section 10.2).
