INFORMATION
A pressure regulating valve should be implemented before the mixing valve station.
This is to guarantee the correct water flow balance between the main leaving water
temperature zone and the additional leaving water temperature zone in relation to
the required capacity of both water temperature zones.
▪ A bypass valve must be installed to make water recirculation possible when all
shut-off valves are closed. To guarantee reliable operation, provide a minimum
water flow as described in table "To check the water volume and flow rate" in
"8.5 Preparing water
