Discharge protection during d.h.w. heating

Presents discharging of the d.h.w. storage tank due to too low flow temperatures during
d.h.w. heating.
Setting range
0...2
The setting activates or deactivates the protection against discharging:
0 Protection against discharging is not active
1 Protection against discharging is active
2 Protection against discharging is active only when heat generation is locked
When protection against discharging of the d.h.w. is active, the boost of the flow
temperature (operating line 126) is checked during the heating cycle:
−
If at least half the boost value is reached, d.h.w. heating will be released
−
If the boost value is less than 1/8 of the value set, d.h.w. heating will be interrupted
(pump will overrun for at least 1 minute) 1 min
