5.5Delayed 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 = 12° C = 4 h.

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.

5.6Remote 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:

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.

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
