Installation recommendations
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. 16.12
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 the circulation pump to the H output via the relay. It is necessary to use a relay type
6VDC RM85-2021-35-1006 .
Setting recommendations
6. During interim periods, when sunlight falls on both solar collectors and the collector currently not
in use becomes overheated, reduce the set
tOP time.
