For the property owner

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 (1 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/external boiler. 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.
