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).

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
press and hold the lowest push button (HEAT) until
the relay is energised and the red LED on the sensor
module flashes. First release the lowest push button

panel.

2. Set the MODE and TIME1 rotary switches for

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.

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.

Every module on the Velbus system must have its own unique address. On modules with a rotary switch the address is
set using the ‘ADDR’ rotary switch (refer to the manual of the relevant module). On other modules e.g. the temperature
controller the address is set via the menu. These addresses may not be altered afterwards.

Assign an action to the wake-up time

The wake-up time can be used with the thermostat program but also to perform a certain action e.g. switching off
staircase lighting, opening the roll-down window shutters, switching certain mains outlets on or off…

As an example, we will automatically open all roll-down window shutters as soon as the set wake-up time is reached.
This can also be configured through the Velbus link software on the computer but here we explain the manual procedure.

1. Remember all address settings of the shutter
modules to reinstate them later on.

2. Set the addresses of all shutter modules to ‘E1’ to
learn the immediately up action for channel 1.
The ‘Mode Up1’ LEDs are flashing to indicate the
learning mode.

Defining zones

It could be interesting to group different sensors in a zone. When that zone is selected, all operations on the controller will
be applicable for all sensors that belong to that zone. This way operating the system can be greatly facilitated.
It is possible to define up to 7 zones e.g. ground floor, second floor, bedrooms …
Default temperature sensors are not assigned to a zone. To assign them to a zone the procedure below should be
followed.

1. Press the ‘Location’ button repeatedly until the
sensor that will to be added to a zone is displayed.

OPERATING THE TEMPERATURE SENSOR VMB1TS

Anti-freeze, night, day or comfort mode indication

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.

Anti-freeze Night Day Comfort

Cooling or heating mode indication

When the temperature sensor is configured to control an air-conditioning system, the frost flower LED (upper LED) will be
lit.
Setting the heating or cooling mode can only be done through a temperature controller (VMB1TC) or through the Velbus
link program.

Heating mode Cooling mode

Air-conditioner or heater active indication

When the heater (valve open) or air-conditioner is active, a red LED will be lit.

The red output LED can indicate following error conditions:

 Flashing (short on, long off): the heater/cooler should be off but it did not

receive the command from the relays module.

 Flashing (short off, long on): the heater/cooler should be on but it did not

receive the command from the relays module.

 Fast flashing: configuration of the sensor chip failed.

Note: as long as the error condition exists the output status will be re­transmitted every minute.

VMB1TC Temperature controller manual – rev 5.0 71

Operation

Pushing the push button repeatedly will switch the module between anti-freeze, night, day or comfort mode successively.

When the comfort, day or night mode LED is flashing, the sensor module is set temporarily (sleep timer) to the indicated
mode. During this time the program is ignored
When the sleep timer expires, the sensor module will resume the program or in case no program is present will return to
its previous setting.

Remarks:

• Anti-freeze mode can not be set temporarily.

• Standard time is set through the temperature controller.

• Overriding temporary mode can be done by pushing and holding the push button. The LED stops flashing and the

sensor remains in the selected mode until the next program step is executed.

• Local operation can be locked or unlocked via a temperature controller VMB1TC or via the Velbus link program.

• When the sensor module is set to manual mode via a temperature controller VMB1TC or via the Velbus link program,

local operation will be locked.

Temporarily switching between comfort, day, night or anti-freeze mode

In rooms equipped with a temperature sensor VMB1TS, the heating (or cooling) can be set to 4 modes (comfort

, night or anti-freeze - ). Every mode has a preferred temperature setting.

The heating (or cooling) can be forced temporarily (sleep timer) into a certain mode. During that time, all program
instructions will be ignored. Once the timer expires the normal program is resumed or when no program was active the
device returns to the previous mode.
This could be useful e.g. to switch the heating of the bathroom to comfort mode for an hour.

Temporarily switching between the different modes is done by pushing the push button on the temperature sensor
VMB1TS or via this module.

PROGRAM INSTRUCTIONS LOCATION

This chapter is only applicable when multiple temperature controllers are connected to your Velbus installation.
It can be skipped if you have only one controller connected.

Prior to start programming it is important to determine which temperature controller will hold the program instructions for
the rooms, zones and ‘all rooms’ to avoid that multiple controllers contain different instructions for the same rooms or
zones.
The instruction set will be available from every controller.

1. Determine the temperature controller that will hold
the program instructions for a certain room or zone.

2. On that controller, press the ‘Location’ button
repeatedly until the desired room, zone or ‘all rooms’
is displayed.

VMB1TC Temperature controller manual – rev 5.0 85

PROGRAMMING

The controller can handle up to 32 temperature sensors VMB1TS. Every room that needs to be heated or cooled must
have its own temperature sensor. These rooms can be divided over 7 zones if desired.
For every room or zone a program instruction set is available. There is also a program instruction set foreseen for all
rooms together.
In every program a maximum of 31 instructions can be stored.

A program instruction consists of 3 parts:

1. The days on which the program instruction is applicable:

• Day program: every Monday, Tuesday, Wednesday, Thursday, Friday, Saturday or Sunday

• Working day program: from Monday to Friday (included) or from Monday to Saturday (included)

• Weekend program: every Saturday and Sunday

• Week program: every day

2. The exact time at which the instruction is to be executed:

• Exact indicated time

• The wake-up time plus or minus a certain time period

• The go-to-bed time plus or minus a certain time period

3. The mode to which the heating or air-conditioning should be set:

• Comfort mode

• Day mode

• Night mode

• Anti-freeze mode

Tips:

• Program instructions that are applicable for all rooms should be programmed under the ‘all rooms’ program. This
way the instruction has to be entered only once in stead of for each room separately.

• The same goes for common program instructions that are valid for all rooms in the same zone. Select the zone on
the controller and enter the program instruction into the zone program.

• Program instructions that are unique for a room must be entered into the program of that room.

• Consider using wake-up or go-to-bed times inside the program instructions. When a certain instruction needs to be

carried out at a different time, only the wake-up or go-to-bed time needs to change, not the whole program.
For example, set the heating for bathroom, kitchen and living room in day mode half an hour before wake-up time;
set the bathroom heating back to night mode 1 hour after wake-up time. If one feels like sleeping longer or getting
up earlier, only changing the wake-up time is needed.

Remarks:

• As soon as a program is available for a certain room, a ‘

p‘ will appear on the display behind the mode symbol.

VMB1TC Temperature controller manual – rev 5.0 93

DIFFERENTIAL THERMOSTAT

Using two sensors, a differential thermostat can be created. When the temperature difference between both sensors
crosses a preset value, a relay channel can be activated.
To achieve this, the first sensors must know the address of the second one. The second sensor must than be linked to a
relay channel. The temperature difference value is set on the first sensor.
To create a differential thermometer the set temperature difference is added to (or subtracted from) the measured
temperature of the first sensor and this value is than sent every 6 seconds as desired temperature to the second sensor.
The settings can be done via a temperature controller VMB1TC or via the Velbus link program

The passage automatically 3° cooler than the office

When the sensor module in the office is set to day-mode, the temperature in the passage must be 3° lower than the
office. Is the day temperature of the office is set to 20°C the desired passage temperature will be 17°C.
When the sensor module in the office is set to night-mode, the temperature in the passage must be 3° lower than the
office. Is the night temperature of the office is set to 15°C the desired passage temperature will be 12°C.

Office Passage

Configuration:
The easiest way to configure the system is to use the Velbus link program via a PC connected on the Velbus PC interface
(VMB1USB, VMB1RS of VMBRSUSB).

However, configuration can also be done without the aid of a computer. Refer to the procedure below.

Link the heating output of the office sensor to a relay channel (ex. channel1).

1. Set the office sensor module in anti-freeze mode by
pressing the push button on the front panel
repeatedly until all LEDs are off.

3. Remember the address of this relay module to
reinstate it later on.

4. Set the address of the relay module to ‘C1’. The
‘MODE 1’ LED flashes to indicate push button
learning mode (PBM).

2. Set the MODE and TIME1 rotary switches for
channel 1 of the second relay module to ‘0’ (instant
control).

Passive cooling of a bedroom

During summer time the bedroom is cooled via a fan that extracts air from a cooler room.
Mount a temperature sensor in both rooms. The temperature sensor of the bedroom is set to cooling mode and the
cooling output is linked to a relay channel that controls the fan.
When the temperature in the cooler room is about 3 degrees lower than the bedroom temperature the fan is activated.

Cooler room

Bedroom

Configuration:
The easiest way to configure the system is to use the Velbus link program via a PC connected on the Velbus PC interface
(VMB1USB, VMB1RS of VMBRSUSB).

However, configuration can also be done without the aid of a computer. Refer to the procedure below.

Link the cooling output of the bedroom sensor to a relay channel (ex. channel1).

1. Set the bedroom sensor module in anti-freeze mode
by pressing the push button on the front panel
repeatedly until all LEDs are off.

3. Remember the address of this relay module to
reinstate it later on.

4. Set the address of the relay module to ‘C1’. The
‘MODE 1’ LED flashes to indicate push button
learning mode (PBM).

2. Set the MODE and TIME1 rotary switches for
channel 1 of the second relay module to ‘0’ (instant
control).
