Lamps, awnings, blinds, domestic appliances and so on can all be conveniently switched on and off via the
FHZ1000. Depending on your personal requirements, these can be automatically timed, you can press a
button or use a telephone.
This way, security can be increased considerably through presence simulation, for example (the pro-
grammed switching on and off of various lights in a house).
Different scenarios can be represented using 4 freely programmable macros (a macro refers to a series of several functions/
commands that are carried out one after the other):
• Adjust all living rooms to the lowering temperature with just one press of a button
• Roll out the awning in the winter garden
• Switch on a ventilation system
• Switch lamps on and off
Here you can assign a plaintext name (10 characters) for each device and each macro.
With the help of the FS20TS telephone remote control or the HMS/FHZ radio telephone dialler (neither are included in the
delivery, but are available separately!), you can send these commands while you are on the move from your mobile phone
or from your office.
Ö
You can, for instance, heat up your bath or switch on your outside lights while still driving home in your car.
Despite its wide range of functions, the clearly structured operator prompts and large, illuminated display, amongst other
things, ensure that the system is easy to use.
The exchange of data between the FHZ1000 and the room controls (FHT8b required) and the telephone dialler takes place
over an exceptionally secure bi-directional radio connection in the 868 MHz frequency band.
Thanks to the legal restriction of transmission duration in this band to a maximum 36 seconds per hour (1% duty cycle),
the danger of interference from other radio services is minimised. Furthermore, an additional security code is used for the
data exchange.
A plug-in power supply (unit) and a 9V block battery is used for the power supply. The battery also serves to preserve data
when there is a power failure.
The control centre is suitable for wall mounting using the supplied wall holder and for installation.
b) FHT8b room control/heating control
The FHT8b is installed in the individual rooms and is connected by radio to the FHZ1000 control centre and the FHT8V valve
operating mechanism. The FHT8b measures the room temperature and compares this with the target temperature, which
is manually provided or provided by the time program.
The difference is used by the control algorithm to calculate how far the valve has to be opened or closed in order to achieve
the desired temperature.
The valve position is transmitted by radio to the valve operating mechanism that is mounted on the radiator. This valve
operating mechanism then reduces or increases the heat accordingly.
Alterations to the temperature settings or to the time program can be carried out locally or via the FHZ1000 control centre.
The continuous exchange of the latest adjustments between the room control and the control centre guarantees that both
units always have the same, up-to-date data. The room control periodically registers its status with the control centre, so
that the latter is kept constantly informed of any possible malfunctions.
Ö
No room control is supplied with the FHZ1000 or the economy set; they are available separately.
