6.2.5 "Expert Config" level (only heat generator A1)
Parallel DHW : Only applicable if a storage loading pump is connected to the connection J2 of the heat
generator.
Setting of parallel pump operation during hot water generation.
Off: Hot water priority operation - All heating circuits of the system are locked during hot water
generation. Optional mix valve extension controllers close the heating circuit mix valve.
1: Part priority operation - All heating circuits of the system are locked during hot water gener-
ation as long as the temperature of the heat generator is below the set target value of the hot
water temperature plus the set value of the [T-HS DHW] parameter. If, during hot water gener
-
ation, the temperature of the heat generator drops below the set target value of the hot water
loading plus the set value of the [T-HS DHW] parameter minus the set value of the [Hysteresis
DHW] parameter, the heating circuits are locked again.
2: Mix valve parallel run - During hot water generation, all mixed heating circuits of the system
are released in parallel.
3: Parallel operation - All heating circuits are released during hot water generation.
N E Off, 1 - 3 Off -
T-HS DHW Setting of the excessive increase of the target temperature specification of the heat generator
during hot water generation.
N E 0 - 50 K 20 K 1 K
Hysteresis DHW Setting of the hysteresis for hot water generation. Hot water generation is activated if the tem-
perature measured at the hot water sensor is less than the current hot water target temperature
minus the value set here. Hot water generation is ended if the temperature measured at the
hot water sensor is above the actual hot water target temperature.
N E 2 - 30 K 5 K 1 K
Max DHW loading
time
Setting of the maximum duration of a hot water generation cycle. Then cancellation of hot water
generation if the current hot water temperature does not reach the set target value in the [T-
DHW Setpoint] parameter.
N E 10 - 240 min 60 min 10 min
DHW Off Time Setting of the blocking time after completion or cancellation of a hot water generation cycle.
The repeat request for hot water generation is operated after this blocking time has elapsed at
the earliest.
N E 0 - 180 min 30 min 10 min
DHW Followup : Setting of the follow-up time of the storage loading pump.
=0 min: Follow-up of 5 min, as long as no other request is made to the heat generator.
>0 min: Follow-up for the set runtime, which is not cancelled by another request to the heat
generator. A blocking function activated with the [DHW Relief] parameter also works during the
follow-up time.
Note: This parameter is not available for the GCU compact. The follow-up time is perma-
nently programmed to 5 min. Exception: For "Summer" operating mode, only 1 min.

Max Flow Gradient In this parameter it is possible to set how quickly the T-HS may increase in a certain period of
time before the heat generator goes into locking.
0: Off; >0: Increase in Kelvin per second
N E 0.0 - 5.0 K/s 2.00 K/s 0.06 K/s
Max In/Out Diff Setting of the maximum temperature difference between T-HS and T-Return.
For example:
Difference t
V
- t
R
> [Max In/Out Diff] = burner blocked
Difference t

- t
R
< [Max In/Out Diff] = burner not blocked
N E 0 - 60 K 35 K 1 K
Dt Reverse Setting of the maximum difference between t

within the first 5 s when the burner starts. N E 1 - 30 K - - - - 1 K
Burner Starts Sum of all starts that are stored in the firing unit of the heat generator. N S - - 1
Burner Oper Time Overall runtime of the burner in hours, which is stored in the firing unit of the heat generator. N S - - 1 h
