13.3.3
Activation of the radio interface
The radio interface
leaves the factory deactivated
. It can be activated as follows:
a)
Without using additional software the radio function can be activated by pressing the
push-button for over 3 seconds while the display is showing the item ‘M-Bus
address’, (see section 10 “Display” Level 2/Technician’s Loop). The standard factory-settings will be
activated.
b)
The radio function can also be activated using the software ’Device Monitor’. This software can be ordered
separately as an option. The exact procedure for activating the radio function using this software is
described in the accompanying handbook.
After successful activation of the radio function a black triangle will appear permanently in the lower left corner of
the display.
If using the compact mode, for one hour after activation the meter will transmit in installation mode. This means
that format telegrams and compact telegrams will be send alternately. During installation mode at least one meter
of the version being installed (forward or return flow, heat or cooling or heat/cooling, pulse inputs, display units)
must be received by the Engelmann Read-out Software. The format of the telegram will be stored locally in the PC
in an .xml file. After completion of the installation mode only compact telegrams will be transmitted.
13.4
Two additional pulse inputs (optional; only in conjunction with M-Bus or radio)
With this option, additional instruments with pulse outputs can be read out via M-Bus or radio.
General information about pulse inputs:
It is important to note that the acknowledged state of the art technology rules and the relevant legal restraints
(international and local; see 13.4.1 “Relevant norms, standards and literature on the pulse inputs”) are to be
observed.
The installation has to be performed by authorized, skilled persons.
If the regulations and the information in the installation and operating instruction manuals are not strictly followed,
or if the installation is shown to be faulty, any resulting expenses will be charged to the company responsible for
the installation.
