Safety Instructions

The regulator is to be used only in connec-
tion with the listed Bosch gas heating units.
The respective circuit diagram must be ob-
served.
The regulator must under no circum-
stances be connected to the 230 V
mains.
Before installing the regulator, the volt-
age supply (230 V, 50 Hz) to the heating
unit must be interrupted.
The regulator is not suited for installa-
tion in damp rooms.

Application

TR 200 is a room temperature regulator with a
digital time switch (weekly programme; three
heating and one reduction starting times per
day) for controlling the Bosch gas heating
units with continuous control listed below.

TR 200 is in accordance with the regulations
and is recommended for floor-areas up to ap-
2
prox. 80 m .
Room temperature regulators like TR 200 are
not suited for buildings with underfloor heating
systems. In those buildings we recommend
the use of a regulator controlled by atmos-
pheric conditions.
2.1 Scope of delivery
TR 200 includes the room temperature regu-
lator with inserted brief operating instructions
(illustration

2.2 Accessory
An external room temperature sensor RF 1 in
addition to TR 200 is available as accessory.
For example, the use of this temperature sen-
sor is of advantage when the mounting loca-
tion of the regulator is not suited for measure-
ment of temperature (see chapter 4).
Furthermore, a remote control switch (e.g. a
telephone commander) can be connected by
customers (see chapter 6.8).
The remote control switch must be equipped
with a potential-free contact which is suited for
5 V DC.

Mounting

Before mounting the regulator, the volt-
age supply (230 V, 50 Hz) to the heating
unit must be interrupted.
4.1 Selecting the mounting location
It is important for the regulation quality of
TR 200 to select a suitable mounting location.
The installation room must be suitable for the
temperature regulation of the complete heat-
ing system. The radiators installed in those
rooms must not be equipped with thermostatic
valves. Instead, hand valves with pre-adjust-
ment should be installed so that the heating
output of the radiators in the installation room
of TR 200 can be set to the lowest possible
value.
