5.5 Delayed outdoor temperature adaptation
The calculated outdoor temperature is used to determine the flow temperature set point. The
heat response is delayed when the outdoor temperature either decreases, or increases and de-
creases. If the outdoor temperature varies by, for example, 12 °C within a very short period of
time, the calculated outdoor temperature is adapted to the actual outdoor temperature in small
steps. Assuming a
Delay of 3 °C/h, the adaptation would take t C

Note!
The delayed outdoor temperature adaptation helps avoid unnecessary overloads of central
heating stations in combination with either overheated buildings occurring, for example, due to
warm winds, or temporarily insufficient heating due to the outdoor sensor being exposed to di-
rect sunshine.

5.6 Remote operation
Apart from measuring the room temperature, the Type 5244 Room Sensor (PTC sensor) and
Type 5257-5 Room Sensor (Pt 1000 sensor) offer the following opportunities of influencing the
control process:
4
Selection of the operating mode:
– Automatic mode
– Day mode
– Night mode
4
Set point correction: during rated operation, the room temperature set point can be in-
creased or reduced by up to 5 °C using a continuously adjustable rotary knob.
When the room sensor is activated, the measured room temperature is displayed. Nevertheless,
it is not used for control unless the Optimization, Adaptation, or Flash adaptation functions
