Mains Connection; Operation - Bosch TR 200 Manual

TR 200
For the mounting location, select an interior
wall if possible and take care that neither
draughts nor heat radiation (not from behind
the wall, either, e.g. through ducts or hollow
walls, etc.) can have effects on the regulator.
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 200 to the heating unit must be used:
Length up to 20 m 0.75 mm
Length up to 30 m 1.0 mm
Length over 30 m
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.

amateur radio sets , microwave equipment, or
similar are to be expected the cables leading
test signals must be shielded.

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
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

TR 200 has some operating elements which are
not needed often after installation and initial oper-
ation.
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
el". All other operating elements make up the
so-called "2
erating level" res. "service level" for the expert.
All special operating states are indicated by a
2 2
up to 1.5 mm
displayed text or by control lights. This also
