7204 Max. temperature buffer cylinder

Heating of the buffer cylinder ends when the buffer
temperature reaches the set value.
Note
■ This function is only available for system schemes
1 and 2 if "Enable buffer cylinder/low loss header
7200" is set to "1" or "2".
■ If the value set here is below "Max. flow tempera-
ture heating circuit 200E", the system may not be
able to supply a connected heating circuit with the
calculated flow temperature during times of high heat
demand.
7205 Stop optimisation heating buffer cylinder
Stop optimisation ensures that the temperature inside
the buffer cylinder at the end of each time phase in
operating status "Standard" has reached the currently
applicable set value.
Value Meaning
"0" Stop optimisation disabled
"1" Stop optimisation enabled
7208 Temp limit op. status fixed value for buffer cylinder
If the adjusted outside temperature (long term aver-
age) exceeds this temperature limit, the heat pump
control unit blocks the operating status "Fixd value"
(e.g. in summer). The buffer cylinder will then only be
heated to the set temperature for operating status
"Standard".
If this temperature limit is undershot again by 0.5 K
(hysteresis), operation of the buffer cylinder is auto-
matically continued in operating status "Fixd value".

With system schemes 1 and 2, stop optimisation is
only available if "Enable buffer cylinder/low loss
