Wall-mounting kit
Mount the zone kit to the wall by following
the sequence below.
N.B.: in the event it is mounted under the
boiler, keep a minimum distance of 250
mm.
- Place the template (1) on the wall and
mark the kit fixing points and hydraulic
connections indelibly.
- Drill the wall in correspondence to the
marked fixing holes and block the kit (2)
to the wall using the specific expansion
plugs d. 10 x 50 (3) Fig.1.
Hydraulic installation of the kit.
- Connect the kit to the boiler, connecting
fitting (4) to the system return and fitting
(5) to the system flow; the pipes are not
supplied with the kit.
- Connect the kit to the heating system,
connecting the two system return pipes
(8 and 9) to fittings (6), interposing the
gasket (7).
- Connect the kit to the heating system,
connecting the two system flow pipes (8
and 9) to fittings (10), interposing the
gasket (7).
- Insulate the system flow and return pipes
with the specific insulations provided
with the kit.
Electrical installation of the kit.
This kit allows controlling the main zone by
means of the "Comando Amico Remoto
control (CAR
); CAR
must be set on/off
V2
V2
(see CAR
Instruction booklet), whereas
V2
the secondary zone must be controlled
using an ambient thermostat not supplied
as standard (S20-2 electrical diagram). The
ambient thermostat in the secondary zone
must be provided with Class II electric
insulation and 230V voltage must be
applied to its electric contact.
Connections of the boiler.
- Main zone enabling cable: dismount
the boiler casing (see boiler instruction
booklet) and open the rear cover of
the boiler control panel and access the
3-relay board; connect cable R coming
from the junction box (11) to terminal
"51" of the 3-relay board, making it pass
through the cable gland kit (12) and the
free cable gland inside the control panel.
Make sure that the cable gland has been
tightened after connection.
- Cable required by secondary zone:
remove the jumper (if available) on
terminals 57 and 58 and, instead of it,
connect cable "40/41" coming from the
junction box (11). Make the cable pass
through the kit cable gland (12) and that
available in the control panel.
- Once the connection has been completed,
close the control panel and remount the
boiler casing.
Connections of the junction box.
- Zone 2 ambient thermostat connection:
place the ambient thermostat connection
cable of secondary zone inside the kit
cable gland (12) and free cable gland
located on the side of the box (11) and
connect it to terminals 10 and 11 of box
(11) and tighten the cable gland.
- Boiler power supply cable connection:
disconnect the boiler power cable from
the mains and place it inside the free
cable gland located on the box top (11);
then, connect it to the terminal box: the
"
V2
brown wire to terminal L, the yellow/
green wire to the earth terminal and the
blue wire to terminal N; then tighten the
cable gland.
11
Electrical supply connection kit.
- Connect the power cable of the junction
box (11) (marked by the adhesive label
indicating polarities) to the boiler
electrical supply. For the connection,
comply with the polarity Line = brown
wire and Neutral = blue wire.
Attention: if during connection the L-N
polarities are not respected, the boiler
does not detect flame presence and goes
into ignition block.
- Order the path of the wires and fasten
them using cable ties.
- Reapply voltage to the device.
- Close the system draining valve and
restore pressure using the filling valve
(see boiler instruction booklet).
The following pages provide examples on
two different types of installation.
