systems.
APPLICATION
The T7270A2001/T7270A2019 ZAPP Wireless Wall Modules
are used for intelligent room temperature control.
• The T7270A2019 ZAPP Wireless Wall Module measures
the room temperature and transmits the measured values
to the W7070A2000 ZAPP Wireless Receiver.
• The T7270A2001 ZAPP Wireless Wall Module measures
the room temperature and transmits the measured values
to the W7070A2000 ZAPP Wireless Receiver.
Additionally, the T7270A2001 allows the room setpoint
temperature to be adjusted.
The T7270A2001/T7270A2019 transmit the data to the
W7070A2000 at 868.3 MHz.
Additional Features of T7270A2001
The T7270A2001 ZAPP Wireless Wall Module has the
following functions (in addition to those of the T7270A2019):
Adjustment wheel at which you can change the room tem-
perature setpoint directly. The adjustment range amounts
to ± 12 °C, starting from the basic value of 20 °C (in
position 0).

►
Insert the supplied AA batteries with the correct battery
polarity (see Fig. 3). If the red LED of the T7270A2001 /
T7270A2019 flashes, this means that the batteries must be
replaced (see section "Changing Batteries").
►
Place the T7270A2001/T7270A2019 at the installation site,
but do not install it yet.
►
Allocate the corresponding temperature zone to the
T7270A2001/T7270A2019 ─ see System Engineering
(EN0B-0286GE51) for information on the "teach-in"
procedure.
Failed Teach-In
If the teach-in has failed:
►
Improve the data transfer (see below).
►
Repeat the teach-in.
Improving the data transfer
►
When selecting the operating site of each device, ensure
that the distance to radio devices such as radio
headphones, cordless phones, etc. according to the DECT
standard amounts to at least 1 m.
►
Do not install the devices over metallic wall connecting
sockets and at least 30 cm away from the cover of the heat
generator.
►
Correct the installation site of the devices, if necessary.
Please see also System Engineering (EN0B-0286GE51).
