ATTENTION
To measure the room temperature, the heating circuit of the
most occupied room is to be used. Radiator thermostat
valves are used together with correctly designed radiators to
control the external heat gain and should hence be almost
completely open. During the adjustment phase additional
external heat sources like fireplaces, majolica stoves, etc.
should not be used. Furthermore, during the measurement
period excessive ventilation is to be avoided to prevent
external cold from interfering with the adjustment process.
The measurement period covers basically the heating phases.
If the heating curve is correctly set, the room temperature remains
constant according to the set daytime setpoint regardless of the
changes in the outside temperature.
If an automatic correction of the heating curve (heating curve
adaptation) is made at the service level, this parameter can no
longer be manually set. Instead of the slope display the message
HEATING CURVE starts to flash during the adjustment and is
corrected continuously.
Recommended settings:
Floor heating: 0.3 ... 1.0
Radiator heating: 1.2 ... 2.0
Convector heating: 1.5 ... 2.0
The heating curves are limited by the minimum and maximum
temperature limits in their valid range. The relevant flow
temperature is controlled within the limit range exclusively
according to the specified limit values.
With the central device, the jump always occurs with the direct
heating circuit (HC). In case of wall devices, the assigned heating
circuit will be the first. If other heating circuits exist, their slope
values can be selected with the relevant access authorisation and
modified if necessary.
