The Start-up option is used for switching on the loading pump with a delay to a demand. If the adjusted minimum temperature at the allocated sensor is exceeded or the adjusted start-up time has elapsed, the corresponding relay switches on. The Overrun option is used for switching off the loading pump with a delay to a demand. - Page 22 Heating curves Heating system Curve: Set flow temperature = heating curve temperature + remote control + day cor- rection or night correction.
