3.6 Installing flow switch
● Install the flow switch in the inlet pipe on the cold side.
● Make sure that there is a straight section of pipe before the flow switch (minimum
length: 4 x pipe diameter).
● Place the switch on the side of the pipe, not on the bottom due to dirt, nor on the top
due to air.
● Install the flow switch in a G1/2 sleeve (max. length: 29 mm).
● For electrical connections, refer to the heat pump’s wiring diagrams.
● Water flow adjustment range: 1–150 cm/s, adjust according to the minimum flow of
the site.
● With normal flow rates, all green LEDs should be active.
● Alarm delay adjustment range: 1–40 s. Adjust to minimum (~1 s).
Electrical connection 230 VAC. Note that the white wire has to be
insulated.
