Thermostats and room controllers
General
The new thermostat range has arrived
Consisting of 16 families, the range covers almost every
commonly encountered application in heating, cooling
or ventilation. It offers an unbeatable price/performance
ratio and is presented in a unified and elegant design.
Applications include low voltage (AC 230 V) and extra
low voltage (<AC 50 V). All devices meet the require-
ments for CE marking.

Thermostats and room controllers
Product range overview
Made-to-measure control solutions
Cost-effective application-specific products are available
for mostly non-communicating individual room control
with
• Heating/cooling
• Fan-coil units
• Variable air volume systems (VAV)
• Air ducts
The products operate in standalone mode.
For fan-coil units, the range includes simple ON/OFF
products and versatile products with two proportional
sequences and automatic fan control.
For heating only and/or cooling only, a wide range of
products are available from a simple mechanical
controller up to a 3-position controller with touchscreen
interface.
For the monitoring of heating systems, domestic hot
water heating and frost protection in air ducts, different
variants of the RAK/RAZ and QAF families are available.
Heating only/cooling only
The RAK/RAZ product family
The electromechanical capillary tube thermostats
RAK-TR, RAK-TW with integrated changeover contact are
clamp-on thermostats and immersion thermostats
in one. The RAZ-TW is a combination of RAK-TR and RAK-
TW. All these thermostats convince by their robustness
and installation friendliness.
The RAA product family
These electromechanical ON/OFF room temperature con-
trollers are designed for the simplest heating and cooling
applications.
The RCU/RDU product family (universal)
The RCU/RDU microprocessor-based room temperature
controllers are designed for heating and cooling applica-
tions with 0…10 V, 3-position and ON/OFF field devices.
RDU room temperature controllers have a digital display
(LCD) and their additional functionality extends the varie-
ty of applications.
The RDD product family
The microprocessor-based room temperature controllers
in the RDD product family have a digital display (LCD).
They are available with a simple time setting facility.
The controllers are designed for simple heating control
with a 2-position control algorithm. Battery-powered and
AC 230 V versions are available.
The RDE product family
The microprocessor-based room temperature controllers
in the RDE product family have a digital display (LCD).
They are available in a version with a 7-day program.
These controllers were developed for simple heating
control with a 2-position control algorithm. Battery-powered
and AC 230 V versions are available.
The REV product family
The programmable room temperature controllers REV..
have a digital display (LCD). They ensure optimum com-
fort in apartments and single-family homes, at the same
time lowering costs by reducing energy consumption: for
example, via the function «automatic optimization» (self-
learning control algorithm). They are available in
24-hour or 7-day time programmable versions with op-
tions for remote switching (via telephone), touchscreen
display, 3-position controlling, wireless connection be-
tween controller and receiver as well as connection to an
«OpenTherm Plus» capable boiler.
The RAV product family
The programmable room temperature controllers RAV are
ideal for users who prefer analog rather than digital oper-
ation. They ensure optimum comfort in apartments and
single-family homes, at the same time lowering costs by
reducing energy consumption: for example, via the func-
tion «automatic optimization» (self-learing control algo-
rithm). Our range includes battery-powered RAV11.
Based on the application, the RAV11.x is equipped with
an analog 24-hour or 7-day time switch.

Heating and cooling
The RAB product family
The electromechanical ON/OFF room temperature
controllers in the RAB family are designed specifically for
fan-coil systems. They are used for control in simple 2-
pipe and 4-pipe systems.
The RCC product family
The RCC room temperature controllers are based on
microprocessor technology and are designed specifically
for moderately complex to complex fan-coil systems.
They can be used for 2-pipe and 4-pipe systems.
The RDF product family with display
RDF is a family of microprocessor-based fan coil
controllers with digital display (LCD). They can be used
for cooling, heating or cooling and heating with auto-
matic changeover. The display and the elegant design
make them especially suitable for offices or hotels where
a display is required. There are variants for 2-pipe and 4-
pipe systems and options for simple ON/OFF,
3-position or analog output signals.
The RDX product family with display
RDX is a family of microprocessor-based controllers with
digital display (LCD). It is designed for 1- or 2-stage
heating and 1-stage cooling with fan coil as well as heat
pump applications with 1-stage compressors and
reversing valve.
VAV
The RCU/RDU product family (VAV)
The RCU/RDU microprocessor-based controllers are
designed for VAV room temperature control acting on
0…10 V, 3-position or ON/OFF field devices. RDU room
temperature controllers have a digital display (LCD)
and their additional functionality extends the variety of
applications.
Monitoring
The RAK/RAZ product family
For temperature limitation of heating systems as well
as domestic hot water, we recommend RAK-TB and RAK-
ST capillary tube thermostats. RAK-ST are similar to RAK-
TB but with increased safety functions. RAZ-ST is in each
case a combination of RAK-TR and RAK-ST. For the safety
limit thermostats (STB), the failsafe function and the
compensation of the ambient
temperature are special features.
The QAF product family
The QAF frost protection thermostats can be used for
frost protection in air conditioning systems. The QAF
family consists of purely electromechanical models with
ON/OFF output as well as capillary tube thermostats with
electronic measurement and modulating as well as
ON/OFF outputs.
