18.3. Solar Application scheme C
Loading of DHW reservoir from a solar panel with additional function of heat discharge to drain
system, when the reservoir maximal temperature ( TDHWmax ) is exceeded.
In this layout, T3 sensor is optional and its connection is not required.
Electro-valve must be connected to P2 pump outlet.
Fig. 18.3 Application scheme C
Installation notes
1. For the controller to count heat output, install additional CT6 sensor on the outlet of lower pipe coil
from DHW reservoir and connect to
T4 input. The sensor must be installed possibly near the
connector pipe.
2. T3 sensor shows temperature in upper part of the reservoir, its connection is not required.
3. Circulation pump is connected to H output through a relay with contact current not lower than the
current of the circulation pump. It is recommended to use relays with two switching tracks, see
details in section 17.2.5 Output H output.
4. Discharge valve coil connected to P2 output must by adjusted to ~230 voltage, see fig. Fig. 18.3,
otherwise the valve should be controlled indirectly by an additional transmitter.
Setting notes
1. Heat discharge valve works until T2 drops below TDHWmax-HP2 . Do not set HP2 value too high
as this result in large heat discharges.
