Installation recommendations
1. For correct operation the system must be equipped with return valves mounted on the solar panel
outlets. In other case, starting circuit of
A collector will affect operation of B collector sensor,
causing poor performance.
2. For the controller to count heat output, install additional CT6 sensor on DHW container lower pipe
coil and connect it to
T4 input. The sensor must be installed possibly near the connector pipe.
3. 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
4. With the use of additional sensor T4 , the controller allows effective controlling of P2 pump that will
be started, when the temperature of return from exchanger reaches dTP2 value.
