FA ROTEX Solaris RPS3 25M - 03/2010
Operation
– The solar return is taken from the solar zone of one of the connected hot water storage tanks via the return connection pipe
(Image 3-32, Pos. 5).
– The common return is pumped to the collector array via the pump(s) (Image 3-32, Pos. 4) controlled by the Control unit RPS3
25M.
– The water is heated in the collector array and is fed as the solar flow into the DHW storage tank via the flow distributor pipe
(Image 3-32, Item 6 ).
