The <STRONG>equithermal control is active</STRONG>. At night, the <STRONG>required</STRONG>&nbsp;reduced room temperature is set to 18 °C by the time program. <STRONG>The current room temperature is higher e.g. 20 °C, but the Vitodens is heating</STRONG>. Outside temperature is e.g 0°C.</P><P>&nbsp;</P><P>I would like to know if the control algorithm takes into account the room temperature or how does the system work ?</P><P>&nbsp;</P><P>Regards</P> Wed, 18 Oct 2023 10:57:02 GMT kalistak 2023-10-18T10:57:02Z https://community.viessmann.de/t5/Gas/Vitodens-100-W-B1HF-32-equithermal-control/m-p/371736#M100734 <P>Hello,</P><P>I have&nbsp;Vitodens 100-W B1HF-32 with installed&nbsp;<STRONG>external temperature sensor</STRONG> and the <STRONG>Vitotrol 200-e</STRONG> with <STRONG>room temperature sensor</STRONG>.
