The Herz 3 F800 16 transceiver
The Herz 3 F800 16 is a 16-channel receiver of signals from TP-1xx
wireless thermostats working on a frequency of 868.1 MHz. It can also
be used with Herz thermostats 3 F800 50 or 3 F800 55 digital bus
thermostats. The Herz 3 F800 16 can efficiently control multi-zone
heating
(including
thermoelectric
valve-actuators
to
replace
thermostats on radiators) or cooling systems. The receiver has a
special „ON indicator” channel which turns the heating to Stand-by
economy mode. It is designed for heating system control and is not
suitable for extending hardwired alarm systems via wireless detectors.
Due to the maximum current limits of the outputs, pulses switching
the outputs off for short moments are used (when more than 8 outputs
are used). Therefore the Herz 3 F800 16 should only be used with
thermoelectric valve-actuators. It should not be used to control any
relays, semiconductor switches etc. LEDs on the receiver’s front cover
indicate the status of each output channel.
The built-in power relay modules can be used for pump and boiler
control. Both relays work with OR logic: they are switched if any of the
1
–16 outputs is activated.
Output no. 16 can be used with a wired temperature sensor for DHW
control (Domestic Hot Water).
Installation
Attach the unit to the desired location with two screws. Route all the
cables to the unit before you tighten the case.
Fix the output terminal cables (4) firmly inside the box by the
mechanical grips if using flat cables. If you use round cables from the
actuators remove the hole covers on the box bottom first.
Note: Only a qualified technician should provide installation and
servicing. The user is not allowed to open the cover and/or make any
modifications. The mains cable must also be fixed outside the
receiver’s case. Replace the mains plug if necessary for your country.
The output/input terminals:
– the input terminal for the digital bus connection (for
thermostats of the relevant type).
– the input terminal for cooling/heating mode:
Disconnect = Heating (default setting) ; Connect =
cooling.
– the STAND-BY input. This terminal can be used for
remotely controlling the mode in which all the output
channels (4) will work, switching between two
possibilities: A) Terminal disconnected: The outputs
may
be
controlled
by
thermostat
signals
demanding/stopping
heating
B)
Terminal
connected: All outputs respond to the Stand-by
temperature demanding heating. The status of this
channel is shown by the „ON indicator”.
– the input terminal for the high-temperature-cut-off
wired sensor. It is designed for the TS-80 sensor.
– the input terminal for DHW control. Once it is
connected output no. 16’s reaction is related to the
domestic hot water tank. It is designed for the TS-80
sensor.
– the output terminal for the alarm signal. There is a 10s
pulse in events concerning freezing alert signals or
reaching the hi-temperature. It is possible to set
parameters for the freezing and the hi-temperature on
the LCD module or on thermostats. This output is
prepared for the GD-04 only .
Power terminals of the power module:
1
–16
– 24VDC channel outputs. The Herz 3 F800 16 has
pulsed switching.
– RJ-45 connector for an LCD module or additional
Herz 3 F800 16 transceiver.
Mains Power Terminals of the power module:
– mains power supply output for the circulatory
pump (use an external fuse for its protection).
– mains power supply output for the heat exchanger
(use an external fuse for its protection). Can be
used as a spare relay. It is recommended to
check the correct connection of the relay with the
manual of the connected device.
– power terminals for the power cord.
The buttons:
–
or
>
(left, right arrow) for the
enrollment of wireless devices
–
RESET
button, to delete enrolled devices for a
channel
The buttons are disabled if the LCD module is connected
The transceiver is protected against shorts on the outputs. If an
output is overloaded (the current is greater than 0.4A), then the output
is automatically disconnected. A fault is indicated by rapid red flashing
of the corresponding LED indicator. The output is under constant
monitoring and when the output current decreases below 0.4A the
output will be switched on again.
It is possible to connect an AC-100LCD module via the RJ connector
(7). The LCD module provides you with features allowing advanced
programming and saving energy.
If it is necessary to have more channels, then it is possible to
connect another unit via the RJ-45 connector. In this case the
minimum distance between the units is 2m. If there is more then one
unit in the installation it is obligatory to use an LCD module. The unit
with an LCD module works as a master unit, the other as a slave unit.
Do NOT connect another LCD module to the slave unit.
There is a connector for an external antenna (3) (e.g. AN-80 or AN-
81) and a covered hole for the cable on the bottom left of the housing.
If the external antenna is used no further modifications to settings or
connections are necessary.
