Compatibility:
Compatibility with iThink module: V1.0 or higher.
Compatibility with Mordomus software: Mordomus iThink
V2017 or higher.
ATTENTION:
Never crimp or cut cables while they are connected
to powered equipment.
The module is not provided with additional protection
against short circuit, therefore it is recommended to
use a power supply with the correct specifications.
Mordomus shall not be liable for any damages
resulting from the use of our equipment outside the
specifications and/or for a purpose other than that
intended.
Do not twist or bend the leads of the temperature
sensor excessively;
Due to the nature and reduced size of the module it is
not contained in any type of encapsulation and
should be treated accordingly. Prevent contact
between the module and any metallic or conductive
surface.
When using a low cross section cable there might be
voltage drops that could force the module into
undervoltage protection mode.

MDiBus and 15VDC power supply connection: The iTM1 should
be connected to the MdiBus and the power supply via the iPSB
module using UTP Cat6 cable.
The wire colors and connections in
the previous Table should be respected. The example specifies the
wiring from iTM1 to the branch 1 of the iPSB module.

Connecting more than one iTM1 on the same iPSB branch:
The connection of multiple iTM1 modules in the same extension is
possible as long as the MDiBus passes through all the iTM1
modules and the last iTM1 module has the MDiBus return
connected to the MDiBus A IN and MDiBus B IN. See

Enrollment:
To enroll the iTM1 module proceed as follows:
1.
Make sure that the iTM1 is powered by a suitable
power supply and connected to the MdiBus via an
iPSB module
and
2.
In the Mordomus software access the menu
Configurations and access the sub-menu Modules/
Addresses.
3.
On the iTM1, press and hold the addressing button
for at least 1sec. The green LED
slowly until the addressing is complete.
4.
The iTM1 should be added automatically to the list
image
1,
and the green LED
should stop blinking.
The frequency of the temperature updates (refresh rate) can
be defined in the Mordomus Software by selecting the desired
iTM1
input in Configurations, Modules/Addresses. Possible values
3
are: 1, 3, 5, 10, 30 seconds and 1, 3, 5, 10, 30 minutes. The default
is 10 seconds.
2
Reset:
To perform a reset to the module, interrupt the 15VDC
3
power supply for 5 seconds.
