With a purely centrally controlled system (Not Velbus),
which of the following can result in a complete system failure if it were to breakdown?

Select as many as you think apply.

Not just that a small part of the system would stop, which of these options would cause the whole network to fail.

Strictly speaking, does a Velbus system require a central processor in order to perform "mission critical" functions, like lighting control or heating management.

Mission Critical = Where a user presses a button and a light is toggled or a thermostat calls for heat and the zone and heat source responds, without the risk of failure.

Non Mission Critical might be an advanced feature like a button press triggering music playback.

# Cooling zone flow control

# Fountains

# Window blinds

# Roller shutters

# LED strips

When connecting heating flow control devices (IE Wax Thermal Actuators or 2 port zone values) for heating or cooling for control by Velbus,
what is the standard plumbing term used to describe the installation style.

Where each zone or device has an individual flow control device, as required by the legislation of 2019.

(*Part L, 'Conservation of fuel and power' - Required 2 zone minimum.)

When planning to use ELV lighting,
which of these phrases best summarises the main concerns you should address?

ELV - Extra Low Voltage

How many locations / cabinets  / nodes can a property have to house the Velbus output modules?

IE
The number of electrical cabinets that house Velbus DIN rail modules.

When considering which lamps to use within a project and how to connect them can you assume that all Mains Replacement LED lamps the same?

Can standard water driven convection radiators be used as zoned heating sources in a Velbus system?

How many channels of a VMB7IN support pulse counting?

Where a connected sensor is capable of indicating a value.

For example, a Water flow rate or electricity meter

How many button status’ can a VMB7IN report?
A button status in this case could be anything from a momentary button that a user presses to a magnetic sensor on a window.

The VMB7IN will translate these physical events into digital signals for other modules to react to.

Where a final load in a building requires a three phase supply, can this be controlled by Velbus?

Final Loads that are to be connected to a Velbus system, must all be wired as ---

(Final loads being the device or collection of devices to be controlled by each output channel)
