The T24-V42(-V02)LON control module can be mounted as follows:
Observe all local installation and mounting regulations.
Wall mounted with 2 screws
DIN rail (EN 50 022-35 x 7.5) at least 120 mm long
The T24-MP or TG-R10000 room unit can be mounted as follows:
Wall mounted. Not in niches or bookshelves, not behind curtains, above or near heat sources and exposed to direct solar
radiation. Mounting height is about 1.5 m above the floor. The connecting wires can be run to the controller from a recessed
conduit box.
The room control module is designed for AC 24 V operating voltage.
However, when mounting in an environment greatly exposed to EMI, use only shielded cables.
- The low voltage must comply with the requirements for safety extra-low voltage (SELV) as per EN 60730.
- Use safety insulating transformers with double insulation as per EN 60742; they must be designed for 100 % on-time.
- Supplying voltages above AC 24 V to low voltage connections may damage or destroy the control module.
- Wiring terminal: Fixed screw terminals, 0.5...1.5 mm .

T24-V42(-V02)LON+T24-MP Operation and setting
MP-Bus - VAV Compact addresses
The MP-Bus is the Belimo master/salve bus. Up to 8 salves can be connected to an MP-master devices. Each MP salve must be assigned a unique
MP address between MP1 to MP8 before it can be operated on the
MP-Bus. Belimo VAV Compacts are set to PP (point-to-point) addressing
on delivery. PP is the required conventional control setting for CAV/VAV
functions with 0...10 / 2...10 V signals.
For T24-V42(-V02)LON control module, it can manage up to 3 MP devices
(MP1 to MP3). MP1 is for T24-MP, MP2 and 3 are for VAV-Compacts
connection, MP4 to 8 no useful at this stage.
T24-V42(-V02)LON, MP-Bus requirement
VAV Compacts can be pre-addressed with the PC-Tool (address / deaddress device). Pre-addressed VAV Compacts are automatically detected
and read as soon as they are connected to the T24-V42(-V02)LON.
Pre-addressing with Belimo PC-Tool V3.1
Room Unit - T24-MP;
It is default as MP1, no need to address with PC-Tool
When 1 VAV Compact connected with T24-V42(-V02)LON;
Pre-address it to MP2 or MP3 with Belimo PC-Tool
When 2 VAV Compacts connected with T24-V42(-V02)LON;
Pre-address it first actuator to MP2 and second actuator to MP3 with
Belimo PC-tool
Address setting
a) On the Room Unit - T24-MP
From the room unit enable ( ), the LCD will display "PS" and
have 30 minus allowable to entry into parameter setting mode by
using PC-Tool software. MP2 and MP3 can read together.
b) On the VAV-Compact
If the PC-Tool is connected locally to the service socket of the
VAV-Compact, it can be used to set this MP device. No other MP
devices can be accessed.
PC-Tool connection
Principle of the TG-R10000
Surface mounting TG-R10000 external sensor directly connect to T24-V42
(-V02)LON room module of analoge input (AI) point. This device without
MMI and LCD display. The temperature reading can though Building
Management System (BMS) by LONWork.
The device would not function if T24-MP is connected together.
