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, increases or in-
creases and decreases. 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 out-
door temperature in small steps. Assuming a
Delay
of 3 °C/h, the adaptation would take

Note: The delayed outdoor temperature adaptation helps avoid unnecessary overloads of
central heating stations in combination with either overheated buildings occurring, for exam-
ple, due to warm winds, or temporarily insufficient heating due to the outdoor sensor being
exposed to direct sunshine.
In the operating level, the outdoor temperature blinks on the display while delayed outdoor
temperature adaptation is active. The calculated outdoor temperature is displayed.

5.6 Remote operation
Apart from measuring the room temperature, the Type 5244 Room Panel (PTC sensor) and
Type 5257-5 Room Panel (Pt 1000 sensor) offer the following opportunities of influencing the
control process:
