6.1.13 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 fi rst tank (B46), charging starts to the second tank (B47).
NB: For certain heat sources, e.g. solid fuel boilers, automatic chargers are
recommended, among other things to counteract condensation in the fi re
box.
However, this function cannot be combined with solar system 2 with
EcoTank. This is because the same circulation pump (G46) is used.
“Operation data/Diff thermostat function” displays the information “Status
(On/Off).
i
Ensure a high
fl ow on the pump
(G46) so that a
low temperature
difference of approx.
5-10 °C is achieved
over the EHS tank
during charging.
6.1.14 Pool (accessory)
A pool can be connected to the system using a 3-way valve
(Y50). A heat exchanger should be fi tted to separate the
liquids.
When the pool is heated, the 3-way valve (Y50) changes
direction and the pool pump (G51) starts.
The electric heater is never used to heat the pool.
When a constant fl ow is desired in the pool water, the
pool pump (G51) is connected with a separate supply and
constant voltage.
The expansion card accessory is required to connect pool
heating to your heating circuit.
