The 3-way valve kit, ON/OFF motorization, connected to the control panels of ECFWERA6, permits to set the room temperature by cutting off the
water fl ow by means of the heat exchanger.
The kit is available for all FWB unit models for the supplemental EAH--A6 heat exchanger.
As far as the coupling with the ECFWERA6 control is concerned, position the temperature probe into the appropriate trap.
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 specifi cations:
- power supply: 230 V
- activation: ON/OFF
- total opening time: 4 minutes
Hydraulic kit for the installation of the valve on the heat exchanger.
The fl ow resistance of the connecting valve/hydraulic kit assembly is obtained from the following formula:
where
ΔP
is the fl ow resistance expressed in kg/cm2
W
Q is the water fl ow rate expressed in m3/h
W
K is the fl ow rate identifi ed in the table
V
INSTALLATION
1. The position of water input, connections to heat exchanger and water returning to the circuit is shown in fi gure 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 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 fi gures 2-5 that show the following:
Figure 2: Assembly of kit E2MV307A6 - water connections on the left
Figure 3: Assembly of kit E2MV310A6 - water connections on the left
Figure 4: Assembly of kit E2MV307A6 - water connections on the right
Figure 5: Assembly of kit E2MV310A6 - water connections on the right
4. Connect valve wire to the terminal board on the electric box respecting the positions specifi ed.
