8.7.10 Saving and loading settings
The following settings can be saved and loaded.
Save settings
Here your own settings can be stored; confirm with the
"OK" button.
Load settings
The saved settings can be reloaded using this option.
Load factory settings
The product is supplied with the factory values set. They
can be restored by activating this function. Press OK
to confirm. However, the product and product size are
retained.
!
NB: If the expansion card has not
been installed and Pool has been
defined, the product will emit an
alarm:
Comm. fault expansion card.
8.7.8 Sett. Diff termostat function
The function must be defined before the settings can
be entered. The operating thermostat function is used if
you want to charge your system tank (e.g. EZ 250) from
a water-jacketed stove, or another water source.
However, this function cannot be combined with the
same function in a solar heating system (when e.g. an
EcoTank is connected to an EZ 250). This is because
the same outlets and sensors are used for both
functions.
Information about the operating thermostat function will
be displayed under Operation data.
Charge start diff. temp., °C 7 (3...30)
Here you can set the temperature difference determining
when charging from the heat source is started. The heat
source must be this many degrees warmer than the
tank temperature for charging to start.
Charge stop diff. temp., °C 3 (2...20)
Here you can set the temperature difference determining
when charging from the heat source is stopped. When
the temperature difference between the product and the
tank falls below this set value, charging stops.
Charge temperature, °C 60 (10...80)
Here you can set EcoZenith/EcoHeat's maximum
permitted temperature in the lower tank. The charging
stops if this temperature is exceeded.
8.7.9 Pool
The settings for Pool require the installation of an
expansion card.
See the CTC Solar controls/Expansion card manual for
more information.
