1.1 Explanation of symbols
Warnings
Signal words at the beginning of a warning are
used to indicate the type and seriousness of the
ensuing risk if measures for minimizing damage
are not taken.
•NOTE indicates that minor damage to
property may occur.
•CAUTION indicates possible minor to medium
personal injury.
•WARNING indicates possible severe personal
injury.
•DANGER indicates that severe personal injury
may occur.
Important information
Additional symbols
Warnings are indicated in the text
by a warning triangle and a gray
background.
In case of danger due to electric
shock, the exclamation point on
the warning triangle is replaced
with a lightning symbol.
Important information that
presents no risk to people or
property is indicated with this

1.2 Safety instructions
BTo ensure proper function, follow these
instructions.
BInstall and start up the heating appliance and
all accessories according to the associated
instructions.
BOnly have this accessory installed by a trained
and certified installer.
BUse this accessory exclusively in conjunction
with the controllers and heating appliances
listed. Follow the connection diagram!
BNever connect this accessory to 120 VAC line
voltage.
BPrior to mounting this accessory:
Isolate the power supply (120 VAC) from the
heating appliance and all other BUS users.
BElectrical components must be installed by a
trained electrician and the installation must
meet the National Electric Code as well as all
applicable local codes and regulations.
BProvide a dedicated circuit breaker for the
boiler and heating system rated at least 15 A.
BAll line voltage wiring must use at least
AWG14 size cables.
BNever install this device in wet rooms.
BInstruct customers about the functions and
operation of this accessory.
BRisk of scalding during thermal disinfection:
Due to DHW temperatures occurring in excess
of 140 °F (60 °C), Bosch strongly advises to
install a DHW thermostatic mixing valve.
BWhen there is a risk of frost, leave the boiler
switched on and follow the frost protection
information.

2 Information about the appliance
•The FB 100 is used to display device and
system information and to change the settings
shown.
•The FB 100 is prepared for wall mounting.
•In connection with the IPM 2 module, the
FB 100 controls the assigned heating circuit
using a timer program. Three weekly heating
programs with six switch points per day are
available for a heating circuit (one program is
active).
•Number of FB 100 per heating system
–Maximum of four FB 100 in a heating
system with an FW 200.
•In case of power failure, the display goes out.
All settings are saved. The FB 100 receives the
time and date from the outdoor reset control.

3.3 Making the electrical
connections
BFor BUS connection use AWG 18 (0.75 mm2)
cable and do not exceed 492 ft. (150 m) total
length.
BRoute all low-voltage cables separately from
cables carrying line voltage to avoid inductive
interference (minimum separation 4"
(100 mm)).
BIn case of inductive external influences, use
shielded cables.
This way, the cables are shielded against
external influences (e.g. high-voltage cables,
contact wires, transformer stations, radio and
TV devices, amateur radio stations, microwave
devices, etc.).

for one heating zone.
5.1 Changing the room temperature
and operating mode
5.1.1 Changing the specified room
temperature for a limited period
To change the desired room temperature
permanently, Æsection 6.3.2 on page 28.
BSet the desired room temperature using the
dial .
–If the mode selector is set to :
The new temperature applies until the next
switch point. After that, the temperature
specified for the switch point applies.
–If the operating mode selector is set to
/ / : The new temperature applies
until the mode selector position is
changed. After that, the temperature
specified for the selected operating mode
applies.
5.1.2 Changing the operating mode (time-
limited)
To change the operating mode permanently,
Æsection 5.1.4 on page 17.
This function is only available when mode is
switched on.
BPress and release to bring forwards the
next switch point and the associated
operating mode Comfort / Economy /
Frost for the selected heating circuit to the
current time.
The display shows the changed settings.
BPress and hold and simultaneously turn
the dial to change the next switch point.
At maximum, the switch point can be changed
between the current time and the switch point
after the next one.
On exceeding of the next switch point of the
heating program, the function is reset and
automatic operation is active again.
Premature termination of the function:
BPress again briefly.
The FB 100 offers the option of
setting the desired room
temperature for the operating mode
concerned. This temperature entry
is not the actual room temperature.
This is an orientation value that
influences the required supply
temperature for the heating zone.
The function can be used in
situations such as going to bed
earlier, being away from home
longer or coming back earlier.
