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.

control is concerned, position the temperature
probe into the appropriate trap.
ON/OFF 230V VERSION
The kit comprises:
3-way valve / 4 connections
with built-in by pass, made of brass, max. work pressure
16 bar:
Electro-thermal actuator having the following specifications:
- power supply: 230V
- activation: ON/OFF
- total opening time: 3 minutes
The flow resistance of the connecting valve/hydraulic kit assembly is
obtained from the following formula:

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
E2MV107A6
3-way valve kit, ON/OFF motorization, is to be installed before
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:
Figure 2:

- water connections on the left
Figure 3:
Assembly of kit

- water connections on the right
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 .
