Functions of the heating circuit
Note:
Summer mode only becomes effective when the controller is in automatic mode (
).
6.7 Delayed outdoor temperature adaptation
The calculated outdoor temperature is used to determine the ow temperature set point. The
heat response is delayed when the outdoor temperature either increases or decreases or
both. 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 (delay time of 3°C/h) over a time period of
.
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 insufcient heating due to the outdoor
sensor being exposed to direct sunshine. In the operating level, the outdoor tempera-
ture blinks on the display while delayed outdoor temperature adaptation is active. A
small hour glass appears next to the thermometer on the display when this function is
active. The calculated outdoor temperature is displayed.

6.8 Remote operation
Apart from measuring the room temperature, the Type5257-5 Room Panel (Pt 1000 sensor)
provides the following opportunities of inuencing the control process:
− Selection of the operating mode: Automatic mode
Day mode
Night mode
− 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.
