Description of functions
Individual room temperature control
The Contouch room controller (UP 204) measures the
room temperature and calculates a heating command
signal which is sent to the thermal actuator to drive
the valve actuator of the radiator heating.
Weather-compensated heating control
The weather station (AP 257/22) 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
A time schedule defines the time periods the room is
not occupied. During these periods of time, the oper-
ating mode is reduced to Economy with lower tem-
perature 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 ventilation control
The fresh air ventilation can be startet manually on
the Contouch via the fan stages or automatically via
presence detector when the meeting room is occu-
pied.
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 Contouch
Room Controller. In this case, the control of lighting is
stopped and the brightness level in the room is main-
tained 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 meeting
room. The sunlight tracking function continually ad-
justs 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
