DHW charging will be terminated when the temperature reaches the current setpoint. When DHW heating is released for the first time in a 24-hour period, forced charging will be initiated. DHW charging is also started when the DHW temperature lies within the switching differential, provided it does not lie less than K below the setpoint. 23/32 Siemens Switzerland Ltd HVAC Products User Manual OEM The settings in detail CE1U2353en01a 7 November 2007 Charging time limitation Charging time limitation Line no. Operating line 5030 Charging time limitation During DHW charging, space heating may obtain no or too little energy, depending on the selected charging priority (operating line 1630) and the type of hydraulic circuit. For this reason, it is often practical to set a time limit to DHW charging. --Charging time limitation is deactivated. The DHW is heated up to the nominal setpoint, even if space heating cannot draw sufficient amounts of heat for a certain period of time. 10 – 600 DHW charging is stopped after the set period of time in minutes and then locked for the same period of time before it is resumed. During this period of time, the heat produced by the boiler is made available for space heating. This cycle is repeated until the nominal DHW setpoint is reached. When space heating is switched off (summer operation, Eco function, etc.), DHW charging will not be stopped, independent of the selected setting. Discharging protection Discharging protection Line no. Operating line 5040 Discharging protection This function ensures that the DHW charging pump (Q3) will be activated only when the boiler temperature is high enough. • With sensor The charging pump will be activated only when the boiler temperature reaches the level of the DHW temperature plus one half the charging boost. If, during charging, the boiler temperature drops to a level below the DHW temperature plus 1/8 the charging boost, the charging pump will be deactivated again. If 2 DHW sensors are parameterized for DHW charging, the lower temperature is used for the discharging protection function (usually sensor B31). • With thermostat The charging pump will be activated only when the boiler temperature lies above the nominal DHW setpoint. If, during charging, the boiler temperature drops below the nominal DHW temperature minus the DHW switching differential, the charging pump will be deactivated again. Off Function is deactivated. Always The function is always active. Automatically The function is active only if the heat source is not able to deliver heat, or is not available (fault, heat generation lock).

Water pressure min If the pressure acquired at input Hx drops below the set limit value (parameter “Water pressure min“), the appropriate maintenance alarm will be delivered. 5: Water pressure too low 18: Water pressure 2 too low If the pressure exceeds the limit value by one switching differential, the error is cancelled. Water pressure critical min If the pressure acquired at input H1 or H2 falls below the limit value set here, an appropriate error message will be delivered and both burner stages immediately shut down. 118: Water pressure too low 177: Water pressure 2 too low If the pressure exceeds the limit value by one switching differential, the error is cancelled. Device hours run Line no. Operating line 6222 Device hours run This indicates the total number of hours run since the controller was first commissioned. 27/32 Siemens Switzerland Ltd HVAC Products User Manual OEM The settings in detail CE1U2353en01a 7 November 2007 2.11 LPB system Error/maintenance/alarms Line no. Operating line 6610 6612 Display system messages Alarm delay Display system messages This setting enables system messages transmitted via LPB to be suppressed at the connected operator unit. Alarm delay Delivery of the alarm to the OCI can be delayed in the basic unit by setting a delay. This ensures that unnecessary notifications of a service center resulting from short-time errors (e.g. temperature limiter cut out, communication error) can be prevented. It is to be noted, however, that errors occurring for a short period of time, and reoccurring constantly and rapidly, will also be filtered. Action changeover functions Line no.

Operating line 8742 8772 8802 Room temp 1 model Room temp 2 model Room temp P model The room model calculates a fictive room temperature for rooms that have no room temperature sensor. The value calculated for each heating circuit is indicated on these operating lines. This allows boost heating, quick setback and optimum start and stop control to be implemented with no need for using a room temperature sensor. The calculation takes into account the attenuated outside temperature (operating line 8703), the room model gradient (operating line 6112) for switching to a higher setpoint and the building’s time constant (operating line 6110) for switching to a lower setpoint. 29/32 Siemens Switzerland Ltd HVAC Products User Manual OEM The settings in detail CE1U2353en01a 7 November 2007 Index A Action
