3.5.1 Setting of water temperature

The knob for adjusting the water temperature is placed on the steering A1 in the switchboard and may either be put in the OFF position (click function - vertically) or set on the desired mixing temperature. The yellow diode below the control knob indicates the starting point of the temperature adjustment.

OFF

In this position the system will allow the parallel inlet of water from the two water connections into the water tank. This is an advatage if the pressure of the inlet water is low and you can do without the function of temperature regulation.

No adjustment of temperature is provided for, but the water temperature at the two connections may be selected freely (lower than 75°C).

The yellow indicator symbol

on the control panel (section 3.6, Fig. 5, symbol 4) is not lit.

ON 50°C

In this position water from the two connections will be mixed to the desired mixing temperature (e.g. 50°C).

The yellow indicator symbol on the control panel (section 3.6, Fig. 5, symbol 4) will glow constantly as an indication that the temperature adjustment has been activated.

The indicator lamp may start to flash while the system is in operation. This means that the tem- perature adjustment has been cancelled by the controls. This will happen if the water supply from either the cold or the hot connection is so sparse (closed tap, low water pressure) that the system is about to enter to a fault situation: “Lack of water”.

Both connections will then be opened in parallel until a high water level has been achieved. The attempt at mixing to the desired temperature will then be repeated.

The indicator lamp will continue to flash even though the water supply returns to OK and the temperature adjustment is repeated.

Please note: The flashing can only be removed by restarting the system.
