Recommended hydraulic layout for installing a PAC as a stand-alone system on a water network
with thermostatic radiator valves.
The buffer tank connected in series on the
PAC
return (inlet) circuit guarantees the presence of a minimum
volume of water and ensures that the
PAC
operates without "short-cycling", independently of the flow through
the radiators.
