Safety Instructions
The regulator is to be used only in connec-
tion with the listed Junkers gas heating
units. The respective circuit diagram must
be observed.
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 100 is a room temperature regulator with a
digital time switch (daily programme for one
heating and one reduction starting time; equal
for all days of the week) for controlling the
Junkers gas heating units with continuous
control listed below.
TR 100 is in accordance with the regulations
and is recommended for floor-areas up to ap-
prox. 80 m
2
.
The room temperature regulator TR 100 is 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 100 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 100 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 6.7).
The remote control switch must be equipped
with a potential-free contact which is suited for
5 V DC.
