Vaillant VRT15 Room Thermostat User Guide
Why choose Vaillant controls
To get the very best out of the Vaillant boiler or heat
pump you install for your customer, it is always best to fit
Vaillant controls. Our controls are designed and tested to
work with our products only. Not only will they enhance
the heat generator but also offer additional bonuses to
you, the installer, by offering extended guarantees and
rewards for your customers. Fitting a complete Vaillant
controls system can increase efficiency by up to 4%.*
What is eBUS?
The eBUS protocol is the language used by Vaillant
products so they can ‘talk’ to each other. It is this
intelligent communication that allows Vaillant boilers and
heat pumps to carry out more complex decisions rather
than just turning on and off.
eBUS allows our products to make decisions based on
what the heating system requires. For example, eBUS
allows our controls to activate the boiler at only 20%
modulation if only a slight increase in room temperature
is required. It’s this modulation that makes the boiler run
at its most efficient point. This process is called enhanced
load compensation.
Weather compensation is technology that uses environmental data to understand the thermal behaviour in and around a property.
A weather compensating control uses eBUS to communicate with the heating appliance to ensure that when you want 21oC, you get
21oC. This feature is available with the VRC 700/VRC 700f, and our range of senso controls**.
Industry leading diagnostics
eBUS captures data points across the whole heating system. With this data, it can send fault codes and alerts to Vaillant appliances
to alert the user to any issues. It also notifies when services are due. These alerts can be sent to a mobile device if an app is
installed.
Weather Compensation
What is weather compensation?
The weather compensation feature on Vaillant’s smart controls uses local weather data to understand the outside temperature. It
then adjusts the heat going to the radiators or underfloor heating system for optimum efficiency.
When the outside weather temperature is seen to drop, Vaillant’s smart controls will increase the temperature going to the heating
system to ensure it reaches the temperature set for optimum comfort. Likewise, when the temperature is seen to rise, the weather
compensation feature reduces the output of the boiler to ensure it is operating with maximum efficiency.
Our state of the art controls can either be fitted with an outside sensor or use local weather services for ultimate heating comfort
and efficiency.
These smart controls can learn the thermal behaviour of the building and use weather compensation to ensure that when your
customer wants 21oC, they get it automatically.
* When fitted with a weather compensating thermostat.
** An additional outdoor sensor is required for the sensoHOME. Only compatible with single zone systems.
