4. System description
Today, there are many reasons why we should give some thought to efficient energy consumption.
High oil and gas prices are surely the most important of these reasons, however, the desire to use non-renewable resources
responsibly and the need to reduce the strain on the environment are also crucial factors.
We also need to rethink our normal day-to-day requirements. Because of work commitments heating is rarely required all
day long in one and two-person households.
The high demands placed on a heating control system as a result of flexible working times, irregular absence, and so on
can barely be managed by a conventional control system. Modern energy management is required, which guarantees the
efficient use of energy along with the benefits of convenience.
Warmth and comfort should always (and only then) be available as they are required.
The FHZ1000 radio control system fulfils these requirements in an exemplary way and can also enhance comfort and
individual feel-good factor.
Ö
The available system components of the heating control system are described briefly below.

FHZ1000
’
radio control centre
The FHZ1000 radio control centre is the central element of the heating control system, which manages individual room
controls (for example, the FHT8b heating control) and individual valve operating mechanisms (for example, the FHT8V) as
well as the remote switching components of the FS20 wireless control system.
Furthermore, heating can be remotely controlled via the control centre (using room controls/valve operating mechanisms)
and problems with the heating system can be read from the control centre itself and also received by telephone/mobile
phone.
Using the room control (FHT8b heating control), the room temperature can be individually controlled for up to 15 rooms.
The control centre communicates with the individual room controls, which in turn adjust the temperature locally (that is, in
the corresponding rooms) via the valve operating mechanisms.
All settings for the rooms can be conveniently carried out on the control centre and are then remotely transmitted to the
individual room controls. Of course, changes made directly at the location (on the room control itself) are also transmitted
to the control centre (only possible with the FHT8b heating control).
Ö
The FHZ1000 itself can control the room temperature in the room in which it is installed; no additional FHT8b
room control/heating control is required in this room.
Its functions include:
• Control of the room temperature with separate day and night programs for each day of the week
• Up to 8 radiators can be controlled in one room
• Holiday/party function for temporary temperature alteration
• Weekly limescale protection function prevents seizing of the valve
• Antifreeze function
System failures and unforeseen circumstances, such as extreme temperature variations, which point to a malfunction of
the heating system, are visually and acoustically indicated by the control centre.
When you are not at home, the optionally available alarm dialler (HMS/FHZ radio telephone dialler) can also automatically
send a message to you; to your mobile phone, for example. Particularly in the winter, this can prevent costly damages from
arising (frost damage) while you are not at home.
In addition to controlling radiators via the valve operating mechanisms and FHT8b heating control, the FHZ1000 can also
control up to 15 components from the FS20 wireless control system.
