DESCRIPTION
The temperature controller (VMB1TC) forms in combination with one or more temperature sensors (VMB1TS) and relay
modules (VMB1RY or VMB4RY) a programmable thermostat to control a heating or cooling installation.
The different sensors can be adjusted, operated and programmed from one location by using this temperature controller.
Multiple controllers at multiple locations are possible.
It is also possible to define zones to group the sensors.

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.
VMB1TC Temperature controller manual – rev 5.0 11
CONNECTION
To interconnect the Velbus modules the use of twisted-pair cable (EIB 2x2x0.8mm2, UTP 8x0.51mm - CAT5 or
equivalent) is recommended.
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
Normally only 2 ‘TERM’ terminators must be used in a complete Velbus installation. 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 distribution 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 is set via a menu (see § ‘configuration of the temperature controller’ below).
These addresses may not be altered afterwards.
Allocate the relay channels
Every temperature sensor module VMB1TS can steer a relay channel to:
• open the valve that provides hot water to the radiator
• switch on the fan of a convector to speed up heating (when the difference between desired temperature and room
temperature is too high)
• set the boiler in day mode
• switch on the air-conditioning
• switch on the circulation pump (when on of the valves is open)
• generate an alarm at low room temperature (heating system down)
• generate an alarm at high room temperature (valve fails to close)
Every relay channel that is steered by a temperature sensor must be placed in instant control, meaning that the TIME1
and MODE/TIME2 rotary switches of the channel on the relay module must be set to position ‘0’.
The easiest way to allocate those relay channels is by using the Velbus link software via a PC connected to a Velbus
interface (VMB1USB, VMB1RS or VMBRSUSB).
However, it is also possible without the aid of a computer (see manual of the temperature sensor module VMB1TS).
To set up the previous example of a heating system, use following procedures.
14 VMB1TC Temperature controller manual – rev 5.0
Allocate a relay channel to control valve 1
When room temperature drops below the desired value, the temperature sensor sends a request on the bus to energize a
relay. When the room temperature rises above the desired value, another request by the temperature sensor is
transmitted over the bus to de-energize the relay.
In our example, the first temperature sensor must control relay channel 3 of the first relay module to steer the valve.
1. Set the first sensor module in anti-freeze mode by
pressing the push button on the front panel
repeatedly until all LEDs are off.
5. Press and hold the lowest push button (HEAT) of the
first temperature sensor until the relay is energised
and the red LED on the sensor module flashes.
2. Set the MODE and TIME1 rotary switches for
channel 3 of the first relay module to ‘0’ (instant
control).
3. Remember the address of this relay module to
reinstate it later on.
4. Set the address of the first relay module to ‘C3’.
The ‘MODE 3’ LED flashes to indicate push button
learning mode (PBM).

5. Press and hold the lowest push button (HEAT) of the
third temperature sensor until the relay is energised
and the red LED on the sensor module flashes.
6. Set the address of the second relay module back to
its original value.

Allocate a relay channel to control the fan
In our example, the fan of the convector must be switched on when the temperature measured by the third temperature
sensor deviates too much from the desired value. The fan is steered by relay channel 2 of the second relay module.
1. Set the third sensor module in anti-freeze mode by
pressing the push button on the front panel
repeatedly until all LEDs are off.
5. Press and hold the second push button (TURBO) of
the third temperature sensor until the relay is
energised and the red LED on the sensor module
flashes.
2. Set the MODE and TIME1 rotary switches for
channel 2 of the second relay module to ‘0’ (instant
control).
3. Remember the address of this relay module to
reinstate it later on.
4. Set the address of the second relay module to ‘C2’.
The ‘MODE 2’ LED flashes to indicate push button
learning mode (PBM).

Allocate a relay channel for day mode of the boiler
Some boilers can be set to day or night mode. In night mode, the boiler temperature is set approximately 10 degrees
lower. In our example, the boiler must be switched to day mode as soon as one of the sensor modules is in day or
comfort mode. This is accomplished through relay channel 1 of the first relay module.
1. Set all sensor modules in anti-freeze mode by
pressing the push button on the front panel

Allocate a relay channel for the circulation pump
Some valves have a contact that closes when the valve is open. By wiring all the contacts in parallel, the circulation pump
can be steered. For valves that do not have these contacts, a relay can be assigned to the temperature sensors to steer
the circulation pump.
In our example the pump must be active as soon as one of the sensor modules indicates heating is required. This is done
through relay channel 2 of the first relay module.
1. Set all sensor module in anti-freeze mode by
pressing the push button on the front panel
repeatedly until all LEDs are off
5. Press and hold the pushbutton on the front panel of
the first temperature sensor and simultaneously

panel.
2. Set the MODE and TIME1 rotary switches for

Master clock
When your Velbus installation contains multiple modules with built-in clock (temperature controllers VMB1TC and control
panel VMB4PD) it is important that all clocks have the same time setting. This can be achieved by setting the clock of one
module as reference (master). This module will then synchronize the other module clocks every day. This function is
default disabled.

Global alarm
This setting only applies when multiple temperature controllers are connected to your Velbus installation. Default the
global alarm function is disabled. Changing the alarm time on a module that has the global alarm function enabled will
result in changing the alarm time on all temperature controllers that have the global alarm function enabled. For modules
that have the global alarm time disabled, changes in alarm time will only apply to that module.
1. Press and hold the ‘Menu’ button for ±4 seconds to
open the extended menu.

VMB1TC Temperature controller manual – rev 5.0 29
Battery backup
To avoid losing the clock when a power failure occurs, a backup battery (3V Lithium CR2032) can be installed in the
battery holder at the back of the module.
To avoid premature depletion of the battery, only install it when permanent power is supplied to the Velbus system.
The temperature controller can display a message when the battery needs replacement.
