12.9.5 Settings External heat source
(EHS)
Charge start °C 70
This is the minimum temperature required in the external
heat source tank (B47) for the mixing valve to open and
emit heat to the system.
Stop diff °C 5
Temperature difference before charging stops from the
additional heating source.
SmartGrid block cap. No (No/Yes)
Electric operation prioritised. The shunt on the EHS tank
is closed to accumulate heat energy.

SmartGrid" menu.
12.9.6 Settings Diff thermostat
function
The diff thermostat function is used if you want to
transfer heat from a tank with the sensor (B46) to a tank
with the sensor (B47).
The function compares the temperatures in the tanks
and when it is warmer in the first tank (B46), charging
starts to the second tank (B47).
However, this function cannot be combined with the
same function in a solar heating system (when e.g.
an EcoTank is connected). This is because the same
outlets and sensors are used for both functions.
Charge start diff temp °C 7 (3...30)
Here you can set the temperature difference determining
when charging to the EHS tank is started. The
temperature must be this many degrees warmer than
the EHS-tank for charging to start.
Charge stop diff temp °C 3 (2...20)
Here you can set the temperature difference determining
when charging to the EHS tank is stopped. When
the temperature difference falls below this set value,
charging stops.
Charge temperature °C 60 (10...95)
Setting for the maximum permitted temperature in the
EHS tank. Charging stops once the set temperature has
been reached.

HC2 Mixing valve close 120 (Off/1...300)
The time in seconds to position the mixing valve at 50%.
This is done to prevent flow problems when charging
DHW.
This menu is displayed if heating circuit 2 is defined.
