5 Thermal disinfection

When using KBR..-3A appliances with DHW tank it may be necessary to disinfect the

DHW tank and DHW system after long idle periods to prevent bacterial contamination, for example from Legionella bacteria. This step is typically not necessary if the potable water is chlorinated or ozonated.

Greenstar FS 6 720 810 589 (2015/05)

Thermal disinfection | 21

Thermal disinfection can also be carried out automatically and on a regular basis; see operating instructions for the heating control unit included in the scope of delivery.

Thermal disinfection covers the DHW system including the taps. For solar DHW tanks, the solar portion of the tank is not covered.

DANGER: Risk of scalding!

Hot water can result in severe scalding.

▶ Carry out thermal disinfection only outside the normal hours of use.

▶ The water in the tank will take a while to cool down to the set DHW temperature as a result of heat loss. Be aware that, after thermal disinfection, the DHW may be hotter than the set temperature.

▶ If the thermal disinfection feature is activated have a DHW blending valve installed.

Performing a manual disinfection of the DHW tank and system

▶ Close all DHW taps.

▶ Advise occupants of the risk of scalding if no tempering valve is installed.

▶ Set the time and DHW temperature accordingly on the heating control with DHW program.

▶ Set any DHW recirculation pump to continuous operation.

▶ Turn DHW thermostat clockwise to max (approx. 158 °F (70 °C)).

▶ Open all DHW taps, from the nearest to the one furthest away, and draw off hot water until it reaches a minimum of 158 °F (70 °C) at all taps for at least 3 minutes.

▶ Reset the DHW thermostat, DHW recirculation pump, and heating control unit to standard operation.

To cancel the thermal disinfection:

▶ Switch the appliance OFF and ON again.

The appliance starts up again and the current supply temperature is displayed.

6 Energy saving tips

Heating economically

The boiler is designed to provide a high level of comfort while keeping gas consumption and the resulting environmental impact as low as possible. The gas supply to the burner is controlled according to the heat demand. The boiler continues to operate on low fire if the demand for heat drops. The technical term for this process is modulating control, and it reduces temperature fluctuations and provides even distribution of heat throughout the home. This means that the boiler may stay on for relatively long periods but will use less gas than an appliance that continually cycles on and off.

Inspection/Maintenance

To ensure that gas consumption and environmental impact (pollution, etc.) remain as low as possible over an extended period of time, we recommend that you sign an inspection/maintenance contract with a trained and certified heating contractor covering scheduled annual service and maintenance.

Greenstar FS 6 720 810 589 (2015/05)

Energy saving tips | 23

Heating control unit

Use a heating control unit with room temperature influence or a weather compensating control unit and thermostatic valves.

For further information, see the operating instructions for the heating control unit included in the scope of delivery.

Thermostatic valves

Fully open the thermostatic valves to ensure that the desired room temperature is reached in all cases. Allow several days for the system to stabilize after every adjustment and only change the setting for the heating curve or the room temperature on the control unit after the system had stabilized on the previous settings.

Radiant floor heating

Do not set the supply temperature higher than the maximum level recommended by the manufacturer.

Room venting

Do not keep windows cracked for ventilation purposes as it continuously cools down the room without significantly improving the air quality in the room. It is better to vent fully for a short time (with completely open windows).

Turn off the thermostats (if installed) in the room when venting.

Domestic hot water (DHW)

Always set the DHW temperature as low as possible.

A lower setting on the thermostat means a higher rate of energy savings.

Furthermore, higher DHW temperatures result in increased limescale deposits and thereby may impair the function of the appliance (e.g. longer heating-up times or lower output).

Recirculation pump

If there is a DHW recirculation pump installed, use a timer program to control its operation according to the specific requirements (e.g. morning, afternoon, evening).

8 Maintenance

Inspection and maintenance

The operator is responsible for the safety and environmental compatibility of the heating system (see local regulations).

It is therefore recommended to sign a maintenance and inspection contract with a trained and certified heating contractor that provides annual inspection and maintenance. This ensures high efficiency and environmentally compatible combustion.

Cleaning the outside of the boiler and the control unit

Wipe down with a damp cloth. Do not use any abrasive or corrosive cleaning agents.

Environmental responsibility is one of the fundamental company policies of the

Bosch Group.

We regard quality of performance, economy and environmental responsibility as equal objectives.

We adhere strictly to environmental protection laws and regulations.

We use the best possible technology and materials taking into account economic points of view, to protect the environment.

Packaging

For packaging, we participate in the country-specific recycling systems, which guarantee optimal recycling.

All packaging materials used are environmentally-friendly and recyclable.

Old appliances

Old appliances contain materials that should be recycled.

The components are easy to separate and the plastics are marked. This allows the various components to be sorted for appropriate recycling or disposal.
