18.2. Solar Application scheme B
Loading of DHW reservoir from solar panel with additional function of extra heating with a heater,
when the solar panel stops supplying energy and with control of DHW circuit with circulation pump.
In this layout, it is required to connect
T3 sensor and it must be installed in the reservoir over a
heater. If T3 is disconnected from the controller or damaged, it will disable reservoir extra heating
function.
How to connect
H output to a heater via a relay is presented in details in section 17.2.5.
Fig. 18.2 Application scheme B
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 is used for controlling additional heat source ( H output). Disconnection of the sensor will
disable H output and the algorithm of the reservoir loading from collector will work normally.
