Description of functions
Individual room temperature control
The room temperature sensor (QAA) acquires the
room temperature and sends the value periodically to
the central apartment unit (QAX) via KNX RF. The
window/door switches (AP) send window/door status
information to the central apartment unit (QAX) as
well.
The central apartment unit (QAX) manages the time
schedules regarding operating modes and setpoints
for each room individually and sends setpoint infor-
mation to the master radiator actuator of each room.
The slave radiator actuators adopt the actuator posi-
tion information from the master.
Demand-dependent heat generation
When at least one room calls for heat, the central
apartment unit (QAX) forwards a heat request directly
to heat generation (RMH) via heat distribution zone 1
on the KNX bus.
Heat generation (RMH) provides heat only when at
least one of the consumers in the system calls for it
(demand-dependent control).
Weather-compensated heating control
The outside sensor (QAC) sends the outside tem-
perature signal to the heating controller (RMH) whose
flow temperature setpoint is shifted depending on the
outside temperature to adjust the amount of heat
delivered.
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 Comfort level.
Window contact
When one or more windows is/are opened in the
room, the valves are automatically locked. As a result,
heating or cooling energy can be saved because the
system does not try to compensate for energy losses.
Blind protection
The wind speed sensor (AP 257/42) acquires perma-
nently 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 status of lighting (on/off)
· The 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
· The status of lighting, individually or in
groups
· The position of the blinds, individually or in
groups
Energy efficiency indication
Web server OZW772 provides the energy efficiency
indication function for the HVAC system which re-
minds the user of settings outside the limits from the
point of view of energy efficiency. In case of a non-
efficient status, the user will be notified by e-mail or
smartphone app. The limits can be defined by the
user.
