Product information
The Sense ll controller makes it easy to operate your heating
system. Turn the rotary selector to set the required room
temperature in your home or building. The thermostatic valves
only need to be adjusted if an individual room is too cold or too
hot.
Automatic mode with the adjustable time program ensures
energy-saving operation by reducing the room temperature at
certain times or by shutting down the entire heating system
(adjustable reduced temperature). This method of controlling
the heating optimises comfort levels whilst minimising energy
consumption.
DHW (Domestic Hot Water) heating can be adjusted
conveniently and controlled efficiently.
2.1
Product data on energy consumption
The specified product data correspond to the requirements of
the EU Regulation No. 811/2013 which supplements ErP
Directive 2010/30/EU. The class of the temperature controller
is required to calculate the central heating energy efficiency of
an integrated system and is for this reason incorporated into
the system data sheet.
Warnings in this document are identified by a
warning triangle printed against a grey
background.
Keywords at the start of a warning indicate the
type and seriousness of the ensuing risk if
measures to prevent the risk are not taken.
This symbol indicates important information
where there is no risk to people or property.
