* If the outdoor temperature sensor is not connected or the<br />
cable is short-circuited, the controller assumes that the<br />
outdoor temperature is 0 (zero) °C.<br />
** The boiler / flow temperature sensor must always be<br />
connected in order to have the desired functionality. If the<br />
sensor is not connected or the cable is short-circuited, the<br />
motorized control valve closes (safety function).<br />
*** Only for room temperature sensor connection. The room<br />
temperature signal can also be available from a Remote<br />
Control Unit (ECA 30 / 31). See 'Electrical connections, ECA<br />
30 / 31'.<br />
