3. INSTALLATION AND CONNECTION (continued)
3.6 Water flow setting
With the water entry and exit valves being open, adjust the by-pass valve in
order to obtain a difference of 2°C between the inflow and outflow temperature
(see principle diagram § 3.1). You can verify the switch by seeing the entry/
exit temperatures directly on the control panel.
Note: Opening the by-pass valve creates a weaker flow, which leads to an
increase in ∆T.
Closing the by-pass valve creates a stronger flow, which leads to a
decrease in ∆T.
