Velleman VMB1TSW - Manual (Page 13)

Terminator
Normally only 2 ‘TERM’ terminators must be used in a complete Velbus installation. Usually this will be on the end
of 2 bus wires (for example in the attic and in the basement.
On all other modules, the terminator must be removed.
Remark:
In case the wiring contains a lot of branches, still a terminator will be set on the end of 2 bus wires (= 2 terminators).
When communication errors occur, an additional terminator can be set as close as possible to one of the two existing
terminators. However, the number of terminators should be limited as more terminators place a heavy load on the bus
(max 3).
Addressing
Every module on the Velbus system must have its own unique address.
The address of the temperature controller VMB1TCW is set via a Velbuslink©
LED INDICATION
Anti-freeze, night, day or comfort mode
In rooms that have a temperature sensor VMB1TS the heating (or air-conditioning) can be set in 4 different modes:
comfort, day, night or anti-freeze. Every mode has its own desired temperature setting. The selected mode is
indicated with LEDs. The sensor module is set to anti-freeze mode when the comfort, day and night mode LEDs are
off. When the comfort, day or night mode LED is flashing, the sensor module is set temporarily (sleep timer) to the
indicated mode and normal program is suspended during that ‘sleep’ time.
