heating
program
With the heating program, the required room temperature can be programmed for 1
w
eek. The heating program consists of seven 24-hour programs each comprising 3
heating periods. Each of these periods is defined by a start time and an end time. The
actual 24-hour program is shown on the display's time bar the resolution of which is 1
hour. Dark fields represent periods with the nominal room temperature. When start and
end time of a period coincide, the period is inactive.

setback / blocking
time
From the OZW30 central u
nit, the heating program of the QAW20 can be confined by
imposing a blocking time (this blocking time can be overridden on the service level of
the QAW20). During the blocking time, the QAW20 operates according to the selected
operating mode. Outside the blocking time hours, the central temperature setback is
active. In manual operation, the economy button can be pressed to preselect the set-
point that shall apply during the blocking time.
Holiday
function
During the ent
ered holiday period, the QAW20 maintains the minimum temperature
preselected for standby mode. On completion of the holiday period at 00.00 hrs, the
unit resumes automatic operation.
Air
ing detection In automatic operation, the room unit is able to detect airing of the reference room,
w
hich results in a fast temperature drop in the space. In that case:
The heating is switched to standby mode

The unit resumes automatic operation when:
The room temperature rises faster than 1 °C/h, or
The operating mode changes, or
45 minutes have elapsed
Detection of airing is independent of the function of a window switch.
Note
The QAW20 uses ready programmed standard values. These can be retrieved by pres-
sing a certain combination of buttons. Note that in that case, individually selected val-
ues will be cleared!
Standard values
Reserve and data
retention
In the event of a power failure, the clock has a reserve of 12 hours. Individually pro-
grammed values are retained in nonvolatile memory.
Programmable input The QAW20 has a signal input (terminals T1 and T2). The type of input signal and its
handling are programmed on the service level. The following functions are available:
If the measured value of the built-in sensor is not suited as the actual value, a remote
sensor should be installed. The room temperature which is then used is a weighted
mean value of the measured internal and external value, which is displayed and evalu-
ated. The effect of the external sensor can be selected between 0 % and 100 %. With-
