Functions for boiler control
Time-/temperature-controlled disable recharge
If a minimum temperature in the tank is exceeded, disable recharge is activated.
This function can be activated in parallel to the time program.
If the preset minimum temperature (e. g. 45°C) in the tank
is exceeded, recharge of the tank is disabled by the boiler.
If, however, the minimum temperature is no longer reached, recharge is enabled
by the boiler no matter whether the time program blocks recharge or not.
Efficiency-optimized recharge suppression
If the calculated minimum temperature in the buffer tank is exceeded, the
disabled recharge feature is activated. The installer can specify two weighting
factors in menu 1.4.3 for the calculation of this minimum temperature:
Factor 1
Parameter values from 1-10 whereby:
Solar yield
1 = more solar yield, less recharge by the boiler
:
10 = less solar yield, more recharge by the boiler
Factor 2
Parameter values from 1-10 whereby:
Comfort
1 = lower comfort, less recharge by the boiler
:
10 = higher comfort, more recharge by the boiler

A flexible minimum
temperature is thus
calculated once per
day which disables the
recharge by the boiler.
This flexible minimum
temperature is between
›T min. tank‹ and ›T target‹.
