9.5.2.4 Upper tank
In the “Upper Tank” menu you make settings which
affect the operation of the upper part of the tank.
Stop temp. HP °C 55 (20 to 60)
At the selected temperature, the heat pump stops
charging the upper tank.
Start/stop diff °C 5 (3 to 7)
Hysteresis before the heat pump starts or stops
charging the upper tank.
Extra DHW stop temp. °C 60 (20 to 62)
This menu is used to specify the setpoint for the heat
pump to charge hot water.
Max time upper tank 20 (5...60)
This is the maximum time spent by the heat pump
charging the upper tank if it is needed in the lower tank.
Max time lower tank 40 (10...120)
This is the maximum time spent by the heat pump
charging the lower tank if it is needed in the upper tank.
Min. temp. °C 45 (35 to 55)
This menu is used to specify the lowest permitted
temperature in the upper tank.
Add heat upper tank °C 55 (45...80)
Stop temperature for additional heat from immersion
heater. Used when the EcoZenith is in additional heating
status, when no heat from the heat pump is available.
Periodic extra DHW, days 14 (0 to 30)
The menu defines the interval for the periodic increase of
the hot water tank (at 65°C to protect against legionella).
Max. temp. diff. interrupted DHW °C 3 (2 to 7)
If there is a heating requirement, hot water charging is
interrupted earlier than the time at which the maximum
temperature has been reached, in order to avoid the
compressor stopping while hot water is swapped for
heating.
Stop DHW diff. max. 3 (2 to 10)
Hot water charging is normally interrupted in the
hot water sensor, but this can also occur in the
condensation temperature which is calculated based
on the heat pump’s internal pressure sensor. The
condensation temperature is significantly increased
during hot water charging. This menu relates to the
value from the maximum permitted condensation
temperature that interrupts hot water charging. If there
is a heating requirement, the system then diverts to
charging the heating system.
