3.6 Water flow setting

While the heat pump is running and the water inlet and outlet valves are open,
adjust the by-pass valve to obtain a difference of 2°C between the water inflow
and outflow temperature (see Functional Diagram Section 3.1). You can check
the setting by viewing the inflow (T02)/outflow (T03) temperatures directly on
the control panel by following the procedure below.
Then adjust the by-pass to obtain a difference of 2°C between T03 and T02
Press MODE again
to return to T02
(T03-T02 = ∆T = 2).
Press
twice to exit the menu
Note: Opening the by-pass valve creates a weaker flow which results in an
increased ∆T.
Closing the by-pass valve creates a stronger flow which results in a
decreased ∆T.
