Heat + Comfort + Intelligence: The THZ system
This thermo-cyclic individual room control,
which is compatible with all modern heating
systems, is based on a revolutionary control
method. It was developed with the aim of
“saving energy whilst at the same time offering
greater comfort”, patented on
27 January 2000 and successfully launched
to the European market. Tests carried
out at the Technical University of
Dresden's institute of thermodynamics
and building systems engineering
have now been backed up
by practical experience and the definitive
conclusion is: High energy
savings compared to conventional
thermostat controls.
+ Greater comfort
+ Lower energy consumption:
= Greater user satisfaction!

The THZ control starts learning from the moment you switch on and ensures optimum comfort everywhere, throughout all
zones and rooms. The system is modular. At its heart is the ZE central unit, which is connected to the 240 V mains supply
via a mains adapter. As soon as it is switched on, the system automatically tests and scans for all connected system modules.
Wired and wireless system components can be combined in any way you want. Central units with a Mod-BUS interface
are available as an option for networking purposes.
THZ – RG & RS room units
The RG and RS room units are
connected to the system via
a 2-wire BUS. They measure
the room temperature and
continually transmit this data
to the central unit.
You use the RG to set the
temperature you want in increments
of 0.5°C. Both the set
and actual temperatures are
displayed.

The RS unit is designed to
prevent any unwanted adjustment
of the set temperature,
which can only be set via the
ZE central unit. Particularly
suitable for public buildings,
schools, offices, nurseries, etc.
THZ – ZE central unit
THZ – RF wireless room unit
The RF room unit transmits
the set and actual temperatures
to the FE radio receiver
wirelessly (frequency: 868 MHz).
The current room temperature
is displayed. The set-point value
can be displayed at the touch of
a button. Thus, there is no longer
any need for cables, which
is a major bonus where retrofitting
and renovation are concerned.
The RF can be installed
free-standing or wall-mounted.
The ZE central unit, which is
at the heart of the THZ system,
processes the incoming data
stream and calculates the future
temperature profile for each room.
The ZE controls the valves on the
heating circuit distributors and
heating appliances predictively
and at precisely the right time in
conjunction with the ST switching
step, via the SF radio actuator or
the BUS-cabled SK actuator, and
in both directions, driving open
or closed.
THZ – DL data logger PCi-Software
The integrated DL data logger writes
measured data collected over an extensive
period to a standard SD card that is
configured by the THZ. The PCi-software allows
the user to program and visualize all
functions of one or more related THZ-Systems
with a connected PC. Schedule for
schools or offices are programmable.
The integrated Data SD-card can be
analysed with the THZ-Analysis software
provided by THZ. A benefit for installers and
end-users: reducing average temeperature
by 1° saves 6% of energy!

The optional VR flow control
THZ – FV radio amplifier
THZ – FE radio receiver
THZ - SF2 wireless
valve operating mechanism
FV radio amplifiers (up to a
max. of 6 per ZE) are available
as an option to optimize
receiving radio signal in
particularly difficult buildings.
The FE radio receiver forms
the interface between the radio
components and the central unit
to which the FE is connected via
the bus cable. This means that
it can be installed anywhere. If
reception conditions are poor,
up to 4 FE units can be used.
The SF valve operating
mechanism, which is wireless
and battery-operated, is installed
on the heating unit instead of a
thermostatic valve. When it receives
the relevant command
from the central unit, it activates
and shuts off the heating unit
at exactly the right moment. Up
to 30 wireless valve operating
mechanisms can be controlled
by a single central unit.
Not only is the SF wireless valve
operating mechanism ideal to
renovate old installations, but it
also allows existing THZ
systems to be expanded with
ease. Adapters for the most
common types of valve are on
demand. Radio-frequency:
868 MHz.
THZ – VR flow control
THZ – ST/SK switching steps
assumes complete control of the
boiler. This assumes control of the
boiler, two mixing valves, the recirculating
pumps and domestic water.
It adjusts the flow temperature in such a
way that all the rooms connected to the
system have their thermal requirements met
without any loss of energy as a result of excessive
temperatures. How you benefit: No
need to set thermal characteristics.
The ST switching
step, connected to
the central unit via
the THZ bus, is responsible for up to four
controlled rooms or zones. It uses internal
relays to open or close the motor valves/
thermal actuators, etc. The ST is installed in
the vicinity of the heating circuit distributor
(see left). Hydraulic equilibration now
available in automatic mode with new
actors SF2 and SK.
The THZ control automatically adapts to ambient conditions and the habits of users. It functions in a predictive manner and just goes on learning and learning....

Principle behind the intelligent THZ control
What’s new? What’s so different about it?
Conventional individual room controls are sluggish. They take too long to react to the measured room temperature
resulting in delayed switching. As a result, it is always either too hot or too cold. Conventional controls also pay too
little attention to the stored energy within the room, the building fabric and the heating system. Following the brief
opening of a window or a door, this stored energy can bring the room back up to the required temperature without
additional heating taking place. Users of underfloor heating are likely to notice the deficiencies of such temperature
controls more acutely than others because of this sluggish response.
By contrast, the patented THZ control is intelligent, fast and efficient: It calculates in advance when the control valve
or heating appliance needs to be switched on and off. This is possible thanks to a revolutionary and totally unique
control method, which can automatically assimilate information about (and adapt to) the intricacies of any heating
system and take the relevant
predictive action.
So how does it actually work?
It is almost impossible to maintain
a constant temperature when
rooms have windows and doors
and are occupied by people.
Energy is constantly transferred to
and from these rooms: doors and
windows get opened and closed,
people enter and leave, fires and
candles get lit, the room gets
flooded with sunshine or it rains.
Consequently, the actual room
temperature changes all the time
and is invariably never stable. The
various prevailing heat conditions
at different times of the day can
often increase these temperature
fluctuations by several ˚C.
Inevitably, this creates a rather
unpleasant environment, which
we have been accepting for far
too long! On the other hand,
changes in temperature can
provide information about system
constants and ambient conditions
(room orientation/climate/usage).
This is where the THZ control comes into effect, as it uses this information to keep oscillation values at an absolute
minimum. Defined and familiar motions are evaluated continually and keep the control updated in real time. In fact,
the THZ control owes its very name to a German term associated with these micro-oscillations: Thermozyklische
Regelung (= thermo-cyclic control), which means heat oscillation control.
The ability to perform the complex calculations on which the system depends on is all down to the latest microprocessor
technology. That is why all the components that make up the THZ control are built around a microprocessor, which
collects, stores and processes the acquired data and uses it consistently during heating and non-heating periods
alike, whilst continuing learning all the time. The user simply sets the desired thermal confort temperature on the
central unit or any room unit, decides on a time period for a night setback temperature or how the system is to
operate at weekends, and the control gets to work straight away. No further settings are necessary.
The user’s comfort is paramount, come rain or shine. In summer, the THZ can also provide a cooling function.
The installer is given access to special programs, which can be activated on a customer-specific basis. Additional
information may be required depending on parameters (preheating, blocking temperature setting on the RF/RG,
connecting to a building automation system, etc.).
Brand new: Hydraulic equilibration is now available in automatic mode with new components SF2 and SK.
