Line no. Operating line
3825 Charging time relative prio
If the preferred storage tank cannot be charged in accordance with charging control,
priority is transferred to the next storage tank or the swimming pool for the set period of
time (e.g. too great temperature differential between collector and storage tank). As
soon as the preferred storage tank (according to setting Charging priority storage tank)
is again ready to be charged, the transfer of priority is immediately stopped.
If this parameter is disabled (---), charging proceeds in accordance with the Charging
prio storage tank settings.
Line no. Operating line
3826 Waiting time relative prio
During the set time, the transfer of priority is delayed. This prevents relative priority from
intervening too frequently.
Line no. Operating line
3827 Waiting time parallel op
If solar output is sufficient and solar charging pumps are used, parallel operation is
possible. In that case, the storage tank of the priority model can be the next to be
simultaneously charged, in addition to the storage tank to be charged next. Parallel
operation can be delayed by introducing a waiting time. This way, in the case of parallel
operation, switching on of the storage tanks can be effected in steps. Setting (---)
disables parallel operation.
Line no. Operating line
3828 Delay secondary pump
To carry away any cold water resting in the primary circuit, the secondary pump of the
external heat exchanger can be delayed.
