DESCRIPTION
The sensor module can be used to measure and send temperatures over the Velbus-system. In combination with a
relay module (VMB4RY or VMB1RY) a thermostat can be set-up to control a heating or cooling installation.
Setting the comfort, day, night or anti-freeze mode can be done via the local pushbutton of with pushbuttons that are
connected to the Velbus. Different sensors can be configured and controlled from a remote location through a
temperature controller (VMB1TC) or via a PC interface (VMB1USB, VMB1RS or VMBRSUSB) and the Velbus link
software.
The temperature controller (VMB1TC) can also include program instructions to control different sensors.

EMBEDDING THE TEMPERATURE SENSOR
The temperature sensor VMB1TS can be embedded in combination with 2 blank frames VMBFBI and a Velbus cover
plate VMBFDG or VMBFLG.
Push the modules from the back into the cover plate
It is also possible to use a 2- or 3-module wide frame with cover plate from the BTicino Living series.
The module must be pushed into the build- in frame from the front
It is also possible to use a 3-module wide frame with cover plate from the BTicino Light or Light Tech series.
The module must be pushed into the build- in frame from the front.
To build the sensor in into a hollow wall, use a hollow wall pattress.

VMB1TS manual – edition 2 9
OVERVIEW HEATING INSTALLATION
A heating installation usually consists of radiators or convectors, a boiler, circulation pump and a collector with valves
for every radiator group.
Every room is equipped with a temperature sensor VMB1TS which is controlled by one or multiple temperature
controllers VMB1TC. The sensors in turn steer the relay modules VMB4RY (or VMB1RY) that control the valves. As
soon as one of the valves is opened, a relay channel can activate the circulation pump and when one of the sensors
is in day or comfort mode, a relay channel can put the boiler in day mode.
When convectors with built-in fan are used, a relay channel can steer this fan in case the room temperature deviates
too much from the desired temperature, e.g. to speed up heating in the morning.

WIRING
To interconnect the Velbus modules the use of twisted-pair cable (EIB 2x2x0.8mm2, UTP 8x0.51mm - CAT5 or
equivalent) is recommended.
When a lot of modules (more than 10) are connected to the cable or longer cable lengths (more than 50m) are used, it
is important to use a cable with appropriate diameter (0.5mm² or higher).
Connect the bus to the module (beware of the polarity).
Connect the 12V to 18V direct current to the module (beware of the polarity).

Terminator
Terminator
Normally o nly 2 ‘TERM’ terminators must be used in a complete Velbus installatio n. Usually this will be on one
module inside the distribution box and on the module which is physically located furthest from the distribution box.
On all other modules, the terminator must be removed.
Remark:
In case the wiring contains a lot of branches, still only one terminator is placed on one module inside the distributio n
box and one on the module which is physically located furthest from the distribution box. When communication errors
occur, an additional terminator can be used at the end of another branch. However, the number of terminators should
be limited as more terminators place a heavy load on the bus.
Addressing
Every module on the Velbus system must have its own unique address.
On modules with a rotary switch e.g. the temperature sensor VMB1TS and the relay module VMB4RY the address is
set using the ‘ADDR’ rotary switch (also refer to the manual of the relevant module).
The address of the temperature controller VMB1TC is set via a menu (refer to the manual of the temperature
controller).
These addresses may not be altered afterwards.
Set a unique Velbus address for the temperature using the ‘ADDR’ rotary switches, from ‘00’ to ‘FE’, except the
reserved addresses: ‘81’, ‘91’, ‘A1’, 'B1', ‘C1’, ‘D1’, ‘E1’, ‘F1’ en ‘FF’.
The example below shows the setting for address ‘A5’.
ADDR = A5
