Frequently Asked Questions - FW 100 BOSCH

How do I install the Bosch FW 100 thermostat?

Mount the thermostat on a wall at about 1.5 m height, away from direct sunlight and drafts. Connect the wires according to your heating system (refer to the wiring diagram in the manual). Insert two AA batteries and turn on.

How do I set the time and day on the FW 100?

Press the 'Menu' button, navigate to 'Time/Date' using the arrow keys, and adjust the hour, minute, and day with the +/- buttons. Confirm with 'OK'.

How do I create a weekly heating schedule?

Access the 'Program' menu. You can set up to 4 time periods per day (e.g., wake, leave, return, sleep). For each period, set the start time and desired temperature. Repeat for each day or copy settings to other days.

What does 'Frost Protection' mode do?

Frost Protection keeps the temperature at a minimum level (usually 5°C) to prevent pipes from freezing when the property is unoccupied. It is activated manually or automatically in some programs.

Why is the display blank?

Check if the batteries are properly inserted and have enough charge. Replace with new AA alkalines. If the problem persists, press the reset button with a pin for 2 seconds.

How do I override the programmed temperature temporarily?

Press the '+' or '-' buttons to adjust the temperature manually. The thermostat will hold this temperature until the next scheduled event, then return to the program.

6.6 Solar settings

Main menu: Solar

For menu structure and setting ranges → page 30.

Use this menu if you want to limit the cylinder temperature or optimise the set DHW temperature and the set flow temperature based on the available solar energy in your geographical region.

Limiting cylinder temperature

Storing as much solar energy as possible requires a high cylinder temperature.

Limiting the cylinder temperature prevents overheating of the DHW. The temperature setting is transmitted by the ISM module during commissioning.

WARNING: Risk of scalding! If the cylinder temperature is higher than 60 °C.

▶If the cylinder temperature limit is set to > 60 °C, fit the thermostatic DHW mixerTWM 20 (accessory) in the DHW line.

▶Set TWM 20 to max. 60 °C.

T2: Max. solar cylinder temperature: Cylinder temperature > 60 °C only in systems if the DHW outlet temperature is limited by thermostatic DHW mixer.

Solar optimisation

The utilisation of as much solar energy as possible makes it appropriate to reduce the set temperatures called for by the heating appliance. The controller enables this reduction automatically subject to the available solar energy with Optimizing influence DHW and with CH circuit optimizing influence.

For more information for contractors, see → chapter 8.5.3 on page 53.

- Optimizing influence DHW: Maximum reduction of set DHW temperature by effect of solar thermal system.

Example:

- Set DHW temperature = 60 °C

- Optimizing influence DHW = 15 K

- Set DHW temperature for the heating appliance = 60 °C - 15 K

- Provided there is sufficient solar output available, the maximum reduction is set and the heating appliance heats the DHW to 45 °C, with the remaining 15 K being provided by the solar yield.

- CH circuit optimizing influence: Influence of solar output on heat input fed into the heating circuit. At a high value, the heating curve flow temperature is reduced at a correspondingly greater rate (further information for contractors → chapter 8.3 from page 47) to enable greater passive solar energy input through the building's windows. At the same time this reduces a temperature overshoot in the building and increases the comfort level.

- Increase CH circuit optimizing influence if the heating system heats rooms that have large areas of south-facing windows.

- Do not increase CH circuit optimizing influence if the heating system heats rooms that have small areas of north-facing windows.

Optimizing influence DHW and CH circuit optimizing influence do not start until a calibration phase of at least 30 days has been completed after commissioning of the solar thermal system.

10 Energy saving tips

• With weather-compensated control, the flow temperature is controlled in accordance with the set heating curve: The colder the outside temperature, the higher the flow temperature. Save energy: Set the heating curve as low as possible in accordance with the building's insulation and the system conditions (→ chapter 8.3 from page 47).
• Underfloor heating: Never set the flow temperature higher than the maximum flow temperature recommended by the manufacturer (e.g. 60°C).
• Make effective use of the temperature levels and switching points by setting them to suit the preferences of the occupants.

- Comfort

Comfortable living

- Economy

Active living environment

- Frost

Away from home or asleep

• Set the thermostatic valves in all rooms so that the required room temperature can be achieved. Only increase the temperature levels if the temperature has not reached after some time (→ chapter 6.3.2 on page 33).
• Much energy can be saved by reducing the room temperature via economy phases. Reducing the room temperature by 1 K (°C) enables up to 5 % energy to be saved. It is not recommended to let the room temperature of heated rooms fall below +15 °C during the daytime, otherwise the cooled-down walls continue to radiate cold and the room temperature rises higher, leading to higher energy consumption than if an even heat supply is applied.
• Good thermal insulation of the building: the set temperature for Economy is never reached. Nevertheless energy is being saved as the heating system stays off. In that case set the switching point for Economy to an earlier time.
• Don't keep windows slightly open for ventilation. This leads to a constant extraction of heat from the room without noticeably improving the ambient air in the room.
• Vent briefly but intensively (open window fully).
• When ventilating, turn off the thermostatic valve or set the mode selector to Frost.
• Make effective use of the temperature levels and switching times for DHW heating by setting them to suit the preferences of the occupants.

Solar optimisation

Activate the Optimizing influence DHW by setting a value between 1 K and 20 K

→ chapter 6.6 on page 39. If the influence of the Optimizing influence DHW is too great, reduce the value in stages.

Activate the CH circuit optimizing influence by setting a value between 1 K and 5 K

→ chapter 6.6 on page 39. If the influence of the

CH circuit optimizing influence is too great, reduce the value in stages.

11 Environmental protection

Environmental protection is a fundamental corporate strategy of the Bosch Group.

The quality of our products, their economy and environmental safety are all of equal importance to us and all environmental protection legislation and regulations are strictly observed.

We use the best possible technology and materials for protecting the environment taking account of economic considerations.

Packaging

Where packaging is concerned, we participate in country-specific recycling processes that ensure optimum recycling.

All packaging materials are environmentally compatible and can be recycled.

Used appliances

Used appliances contain materials that should be recycled.

The components are easy to separate and the types of plastic are identified. This allows the various assemblies to be appropriately sorted for recycling or disposal.

12 Individual time program settings

The factory settings and personal settings for the time programs are summarised below.
