Mounting the storage tank
sensor
- Insert the storage tank sensor
into the immersion sleeve on the
storage tank and connect the
plug to the connector strip at the
appropriate position (see plug
designation number).
Mounting the hydraulic unit
In order to raise the return
temperature and to ensure the
proper regulatory behaviour of
the boiler, it is mandatory to
install the following hydraulic
unit.
The hydraulic unit should be
installed to the left or right
coming from the boiler or
immediately after the boiler in
the heating feed pipe.
The following guide values must
be maintained when setting the
3-stage rotational speed switch
on the pump:
Boiler Wilo Pump Rotational
speed
stage
20 PICO30/1-6 1
25 PICO30/1-6 2
30 PICO30/1-6 3
40 PICO30/1-6 3
40S PARA30/1-7 1
50 PARA30/1-7 1
60 PARA30/1-7 2
70 PARA30/1-7 3
50L PARA30/1-7 2
60L PARA30/1-7 2
75L PARA30/1-8 2
100L PARA30/1-8 3
In all cases the rotational speed
switch should be set in such a
way that a temperature
difference of 10
– 15 °C is
achieved between the boiler
feed and return.
The actuator on the 3-way valve
has an electrical end position
power-off switch and can
become defective if operated
manually.
Mounting the control
- Lay the lid cladding (2) on the
boiler and support it on the right
side cladding.
- Unpack the control,carefully,
unroll the capillary tube of the
safety temperature limiter (don’t
bend it!) and push it through the
recess in the lid.
- Insert the sensor of the safety
temperature limiter and the
boiler sensor into the boiler
immersion sleeve. The sensors
must be secured using the cable
ties provided in order to prevent
them being accidentally pulled
out.
- Thread the pre-wired terminal
strip from below through the
recess in the lid (2) and plug it
into the control in the correct
position (see label on the
control).
- Connect the protective earth
cable to the boiler lid using the
spade connector.
Check that
the boiler protective earth
cable is connected correctly!
- Connect the plug for the mains
connection and boiler protective
earth cable.
Check that the boiler
protective earth cable is
connected correctly!
- Mount the control on the lid (2)
using the four screws provided.
- Hook in the cover plates (41) if
the boiler is a type L.
- Hook in the lid cladding (2) and
additionally the rear lid cladding
(27).
