TR 100
13
English
Adequate space must be provided above and
below the regulator so that the room air can
circulate unimpeded through the ventilation
openings (hatched area in illustration
).
If the above mentioned conditions cannot all
be met it is recommended to use the external
room temperature sensor RF 1 (accessory)
and to mount this on a more adequate loca-
tion.
When connecting the room temperature sen-
sor RF 1 the built-in sensor in the regulator is
automatically deactivated.
4.2
Mounting the regulator
• Loosen the top (a) from the base (b) de-
press the fasteners on the sides (b1) oft the
base and pull off the top (a) (illustration
).
• The base (b) can be mounted either
– with two screws (c) to a standard flush
connection box (d) dia. 55 mm
or
– with 4 dowels (6 mm) and tallow-drop
screws (dia. 3.5 mm) directly to the wall
(illustration );
Take care that the regulator is mounted in
the right position (the clip must be legible)!
• Connect with the mains accordingly (see
chapter 5).
• Fit the regulator top (a).
4.3
Mounting the accessories
The accessories external room temperature
sensor RF 1 and remote control switch (if ex-
isting) must be mounted according to the reg-
ulations and the respective mounting instruc-
tions.

Mains Connection
The following conductor cross sections from
TR 100 to the heating unit must be used:
Considering the regulations, at least cables of
the construction type H05 VV-... must be used
for mains connection.
All 24 V cables (test current) must be laid sep-
arated from cables leading 230 V or 400 V so
that no inductive influencing can take place
(minimum distance100 mm).
In case that inductive external influences e.g.
from power current cables, contact wires,
transformer towers, radio and television sets,
amateur radio sets , microwave equipment, or
similar are to be expected the cables leading
test signals must be shielded.
The corresponding electrical connection plan
(illustration
to
) is to be followed.
5.1
Accessory mains connection
Connect the external room temperature sen-
sor RF 1 (if existing) as shown in
illustration .
If required, the cables of RF 1 can be extend-
ed with a cable with twisted twin conductors.
This will make sure that the measured values
of the sensor will not be influenced.
Connect the remote control switch (if existing)
as shown in illustration For minimum re-
quirements see chapter 2.2 accessories.
When the switching contact of the remote con-
trol switch is deactivated the heating system
will switch to economical operating mode, “F”
is displayed. When the switching contact is
activated the mode of operation set at the reg-
ulator is also activated (illustration
).

Operation
TR 100 has some operating elements which
are not needed often after installation and ini-
tial operation.
Therefore all operating elements which are
not needed often are covered with a lid.
The operating elements visible when the lid is
closed are part of the so-called “1
st
operating
level”. All other operating elements make up
the so-called “2
nd
operating level”.
All special operating conditions as well as
malfunctions are indicated with control lights
(only for heating equipment with Bosch He-
atronic).
When the lid is closed the time is shown.
