Description of functions
Individual room temperature control
The Room temperature controller (UP 237K)
measures the room temperature and calculates a
heating command signal which is sent to the thermal
actuator which drives the valve actuator of the radia-
tor heating.
Air quality control
The Flush mount sensor (AQR2576) measures the air
quality and calculates a fan command signal which is
sent to the binary output actuator to switch the fan.
Weather-compensated heating control
The weather station (AP 257/32) sends the outside
temperature signal to the heating controller (RMH)
whose flow temperature setpoint is shifted depending
on the outside temperature to adjust the amount of
heat delivered.
Demand dependent heating control
The central control unit (RMB) collects the heat de-
mand signals from the rooms and calculates a total
demand which will be forwarded to the heating con-
troller. The heating controller shifts its heating curve in
dependence on the heat demand.
Time schedule for each room
Time schedules for 10 rooms or room groups can be
defined in the central control unit (RMB). A time
schedule defines the time periods the room is not
occupied. During these periods of time, the operating
mode is reduced to Economy with lower temperature
setpoints. So, during the night, on weekends and
during holidays, valuable heating energy can be
saved. After these time periods, the setpoints are set
back to the Precomfort level.
Presence-dependent heating control
During periods of time when people are detected in
the room by the presence detector, the room tem-
perature is increased to the Comfort level. Afterwards,
it is again lowered to the Precomfort level.
Presence-dependent control of lighting
The presence detector (UP 258E21) allows switching
or controlling up to 4 lighting groups and detects the
presence of people in a square area. When a person
is detected, lighting is switched on to the required
brightness level. When everybody leaves the room,
lighting goes off. A master-slave configuration is
possible to extend the detection area.
Constant light control
Constant light control keeps the room light at a con-
stant brightness level by adding artificial light to the
natural light. The brightness of the light is automatical-
ly and continuously adjusted. Offset settings allow the
configuration of constant light control with just one
presence detector.
Manual switching and dimming are possible via wall
switch. In this case, the control of lighting is stopped
and the brightness level in the room is maintained as
long as presence is detected.
Control of blinds
The weather station (AP 257/22) with integrated GPS
receiver offers efficient control to protect facades from
the sun. Up to 8 facade areas can be defined, which
are automatically controlled – independent of each
other.
Sunlight tracking control and shadow outline tracking
control are other functions which ensure maximum
use of daylight and minimum glare in the office room.
The sunlight tracking function continually adjusts the
blind slats so that they are constantly at right angles
to the sun. Shadow outline tracking controls the
blinds’ position so that the shadow outline keeps a
constant distance to the desk. This optimizes the
utilization of daylight, thus reducing energy consump-
tion for room lighting.
In cold winter nights and when no occupancy is de-
tected in the meeting room, the blinds are lowered to
improve the building’s thermal insulation.
On winter days, blind control raises the blinds to let
the sunshine in und to warm up the room.
Blind protection
The weather station acquires permanently the wind
speed. When strong winds come up, the blinds are
driven up to a secure position.
Remote control and supervision
All rooms can be monitored and controlled on a Web
browser via Web server (OZW). The following param-
eters can be monitored:
· The current status of windows and doors
· The current room temperatures
· The current room temperature setpoints
· The current room operating modes
· The current status of lighting (on/off)
· The occupancy of the rooms
· The current status of the blinds
(raised/lowered)
The following parameters can be changed, if required:
· The room operating modes, individually or
in groups
· The room temperature setpoints, individual-
ly or in groups
· The time schedule for each individual room
or for room groups
· Parameters of the heating plant (operating
modes, setpoints)
· The status of lighting, individually or in
groups
· The position of the blinds, individually or in
groups
