General
Congratulations on choosing to purchase
a SALUS room thermostat. In selecting the
room temperature controller that can boast
some considerable advantages over its con-
ventional, mechanical counterparts. This
controller is very simple to use with its stan-
dard rotary knob and, with its state-of-theart
electronics, it can offer you unparalleled ease
of control for all manner of heating systems.

Technical characteristics
Pulse width modulation (PWM)
Radiant panel heating systems tend to have a
problem with overshooting, i.e. rooms conti-
nue to be heated even after the desired tem-
perature has been reached and the valve has
been closed. The RT 10 solves this problem
electronically and especially effectively using
what is known as pulse width modulation. By
continuously comparing set temperature with
actual temperature, the lengths of opening
times for the valve actuators are regulated
in such a way that the temperature is almost
completely prevented from exceeding or fal-
ling below the set temperature. In this way,
the required temperature setting is regulated
in a precise and convenient way.

Note: When the RT 10 is used with radiator
or convector heating systems, pulse width
modulation can be switched off if necessary
(see ‚Basic settings‘ section).

Valve protection function
To ensure that valves remain movable and
ready for use even when they are unused for
considerable periods – e.g. over the summer
– the RT 10 includes a valve protection func-
tion. Briefly once a week, even when there is
no requirement for any heat, the valve actua-
tors open the valves that they control.

Temperature reduction
Timed and demand-oriented heating control
are amongst the best ways of managing hea-
ting energy in an economical way. The RT10
has an integrated temperature reduction
function which enables you to automatically
reduce the set temperature by 4K with no
need for any costly add-on installation on the
boiler controller. This ‚night reduction‘ can
be activated by an external signal, e.g. time
control from a terminal strip, or using a stan-
dard external timer.

Installation
The RT 10 room thermostat is designed as
an electronic temperature controller for the
electrical fine adjustment of hot-water based
heating systems, and is used for controlling
electro-thermal valve actuators or other elec-
trical devices. It is vitally important that the
maximum switching current specified in the
technical specifications should not be excee-
ded! We are not liable for any form of impro-
per use.

This equipment must only be installed by
anauthorised, qualified engineer, and only in
accordance with the wiring diagram. Instal-
lation must also be in accordance with the
latest VDE regulations as well as your electri-
city supplier‘s regulations. The system must
be in a de-energised state whilst installation
is carried out, and all safety instructions
must be followed to the letter.

The control may only be mounted on a non-
conductive surface. Find a position for the
thermostat where it is not covered by curta-
ins, furniture or anything else. The controller
must not be installed too close to any heat
source (lights, stove, direct sunlight etc.),
nor should it be installed in a position where
it will be exposed to draughts. The control-
ler must be installed in a suitable location in
order for room temperature to be monitored
accurately and accordingly regulated with
precision.
