Layout 3 :
This layout is also recommended for heating installations with wide operating water flow variations (radiator thermostatic valves present in the system). Minimum
system volume is guaranteed by a mixing tank (10). Take care when calculating the volume of water in the installation and only take account of 50% of the mixing
tank's volume.
Example :
For a useful volume of 100 litres the actual mixing tank volume will be 200 litres.
The flow adjustment valve
(11)
is used to balance the flow in heating mode and domestic hot water mode to always ensure optimum PAC HT operation.
