4.5 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 and outflow temperatures
directly on the control panel by following the procedure below.

Then adjust the by-pass to obtain a difference of 2°C between the inflow and
the outflow.
Press

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.
