3 Unit description
The fresh water station is a pre-installed valve
group that was checked for leak tightness; it is
used to transfer heat between the buffer tank and
the domestic water circuit. It contains a pre-set
controller and important valves for operating the
system:
n Ball valves in the primary circuit
n Piston valves in the secondary circuit
n Safety valve in the secondary circuit
n Pre-installed controller
n Temperature probe on the cold water supply
n Temperature probe on the heating supply
n Ultrasonic flow rate meter on the domestic hot
water outlet
n Primary pump that can be shut off
n Ball valve for filling/drainage, for bleeding the
heat exchanger and the pump
NOTICE!
A check for pressure and leak tightness after
successful installation must always be per-
formed before commissioning
