Option (2) VARIABLE FLOW circulating pump
It must be mandatorily controlled from the Mod10 electronic
board (built into the S61).
How to connect the VARIABLE FLOW circulating
pump
The Wilo Stratos Para pump is already standard supplied
with the power supply cable and signal cable, both 1.5m
long.
For longer distances, use respectively cable FG7 3Gx-
1.5mm² m and shielded cable 2x0.75 mm² suitable for
0-10V signal.
To connect the Wilo Stratos Para pump (Figure
4.7
p. 29 or 4.8 p. 29).
1� Connect the brown wire of the pump to terminal "-"
HPMP of the Mod10 board, and the white wire of the
pump to terminal "+" HPMP of the Mod10 board.
2� Isolate the black wire and the blue one.
3� Protect the pump's supply line with a double pole
switch with 2 A delayed fuse (Detail IP, Figure
4.7 p. 29), or connect it directly to the terminals
inside the appliance's Electrical Board (Detail MA,
Figure 4.8 p. 29).
