Ease of operation
The UP 227 as a single room operator
unit controls all room functions. Be it
temperature control with an integrated
temperature sensor or the control of fans,
lighting, blinds or screens, etc. All can
be operated in a uniform way. A key lock
feature is available to prevent inadvertent
operation. An LED on the housing front
facilitates orientation at night and indi-
cates malfunctions should they occur.
Ease of use
The bundling of all functions in a single
unit reduces the effort required for instal-
lation and configuration. Presettings and
a library with symbols simplify commis-
sioning. The room operator unit can be
easily combined with the DELTA frame
programs from Siemens. Being a KNX-
compatible device, it can be seamlessly
integrated into any type of building auto-
mation and control system.
High level of flexibility
The room operator unit controls and
monitors HVAC plant as well as lighting
and shading. A weekly scheduler function
is capable of performing up to 40 individ-
ual scheduling tasks. Three pairs of keys
can be freely programmed. Also, the posi-
tioning signal for HVAC control can be
easily adapted, e.g. to valve characteristics.
Reliable efficiency
Energy-saving operation includes night
mode, changeover to protection mode
when a window is opened and scene
control, for example.
