18.8. Solar Application scheme H

Loading of DHW reservoir from two sets of solar collectors oriented in two directions.

Installation notes

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 reservoir lower pipe

coil and connect it to T4 input. The sensor must be installed possibly near the connector pipe.

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.

Setting notes

1. 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.
