General Hydraulic Layout for a Type 2 (*) Installation
Layout 2 :
This layout is recommended for heating installations with wide operating water flow variations (radiator thermostatic valves present in the system). We strongly
recommend including the buffer tank
(2) as it guarantees that the heating loop capacity is higher than the minimum volume when the maximum number of
thermostatic valves are closed.
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.
