This means:

1.B: Activate the main menu with B.

2.SETTINGS: Using button Hand/or Lgo to SETTINGS and press E.

3.LANGUAGE: Using button Hand/or Lgo to LANGUAGE.

4.Confirm with E: After pressing E, the sub-menu LANGUAGE is activated.

This notation is also used for more than 2 sub-menus.

You can switch the appliance into “ON mode” from any operational mode, as follows:

•B: ON START OPERATION

Confirm with E.

nRemark

Starting up and shutting down the entire appliance is described in chapter 7.

Setting the water temperature via SETPOINT MENU

The water temperature can be set to any value between 40°C and 80°C. Set the water temperature via:

1.B: ON CHANGE SETPOINT

Confirm with E.

2.Use:

-Hto increase the value;

-Lto decrease the value.

-Confirm with E. After confirming, the appliance enters “ON mode”.

nRemark

If the temperature setting is higher than the current water temperature, it is possible that the appliance does not immediately start heating. To prevent excessively frequent switching on and off, there is a heating margin. This margin is set standard to 2°C. The appliance starts heating when the water temperature is 2°C colder than the SETPOINT and continues heating until the water is 2°C hotter than the SETPOINT.

We refer to this margin as the hysteresis. The service and maintenance engineer can adjust this value (see paragraph 9.2).
