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 1 K below the setpoint.

Charging time limitation

 

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 temporarily obtains too little heat.

 

10 – 600

 

 

 

DHW charging is stopped after the set period of time in minutes and then locked for the

 

same 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

This function ensures that the DHW charging pump (Q3) will be activated only when the

 

boiler temperature is sufficiently high.

 

With sensor

 

 

The charging pump will be activated only when the boiler temperature reaches the

 

 

level of the DHW temperature plus 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.

Automatic

The function is active only if the heat source is unable to deliver heat, or is not available (fault, heat generation lock).
