3-WAY VALVE KIT, ON/OFF MOTORIZATION
The 3-way valve kit, ON/OFF motorization, connected to the control panels of FWEC,
permits to set the room temperature by cutting off the water flow by means of the
heat exchanger.
The kit is available for all FWB/FWP unit models.

INSTALLATION
1. The position of water input, connections to heat exchanger and water returning
to the circuit is shown in figure 1 according to the indications on the valve body.
A= heat exchanger water outlet
B= water inlet from circuit
C= water returning to circuit
D= heat exchanger water inlet
2. The 3-way valve kit, ON/OFF motorization, is to be installed before
E2MV107A6
powering on the unit.
WARNING:
Each unit requires a switch (IL) on the feeder line with a distance of at least 3 mm
between the opening contacts, and a suitable safety fuse (F).
The installer is in charge of carrying out the hatched connections.
3. Install the hydraulic unions as indicated in the diagrams of figures 2-7 that show
the following:

4. Connect valve wire to the terminal board on the electric box respecting the positions
specified.
5. Make the electrical connections of the control board following the indications of
the installation manual of FWB/FWP unit .
