8.2 Hydraulic Connection of the Secondary Return Line
The return pump is controlled by the Pelletronic Touch (time program) and a return
temperature sensor.
The running time of the return pump must be as short as possible. The pump should
only be activated at times when there is a requirement for hot water. The running
time must be adapted to the supply network.
In order to maintain heat stratification in the cylinder, the circulation lance is mounted
in the corrugated tube heat exchanger at the accumulator´s hot water outlet. It can
therefore be connected to the domestic water system in the building.
The secondary return line must be connected to the domestic hot water pipe by
means of threaded couplings.
