18.12. Aplikacja schemat solarny L
DHW tank is loaded by two solar collector sets oriented towards two points of compass using one
pump group and collector circuit switching valve.
Fig. 18.12 Application scheme L
Installation notes
1. 3-way/1-way control valve was considered in this diagram. Valve is switched back by means of a
spring. Other valves may be controlled using relays as shown in Fig. 17.11
2. The valve should be so installed that high state of P2 output sets the flow in direction of A-solar
collector.
3. The valve may be connected to solar collector supply. . Valve way is as shown in
item 2.
4. To enable calculation of heat yield by the regulator: install additional CT6-type sensor at the outlet
of lower pipe coil from DHW tank and connect it to
T4 input. The sensor should be mounted as
close as possible to the outlet of pipe coil from DHW tank.
5. Connect circulating pump to H -output through relay of contact current not less than the current of
the pump. It is recommended to use relays with two switching channels – for details see section
17.2.5
Output H .
6. Setting recommendations
7. During interim periods, when sunlight falls on both solar collectors and the collector currently not
in use becomes overheated, reduce the set tOP time.
