4.1.1 Sanitary hot water
The 30AWH units drive a 3-way valve (7) to manage a sanitary water
accumulation tank. The operating logic provides that, in the case of
a request for sanitary water by an accumulation tank (8), the system
controls a 3-way valve to direct the hot water only to the tank and to
operate at the maximum capacity to provide water at 60 °C (compatible
with the operating envelope).
Procedure to install a three way valve:
1. Install three way valve on water piping closer as possible to
AQUASNAP
2. Connect electrically three way valve to N, 18, 10 terminals (1,2 and

programmed operating mode in both heating and cooling mode.
2) NUI code 146 congure SHW logic when Aquasnap unit is in OFF
