CONTROLLER INSTALLATION
Hazardous voltage is present inside the controller and on its output cables.
Therefore, it is absolutely forbidden to install the device prior to
disconnecting its power supply. Such installation must be performed by
qualified technicians only. Do not install a controller showing signs of any
mechanical damage.
a)
mounting the controller:
⚫
using a pair of screws mount the controller box on a wall or any other supporting
structure (screw anchors with screws are supplied with the controller);
⚫
using fasteners fix controller cables to the wall.
b)
fixing the sensor:
⚫
do not immerse the sensor in liquids nor install them at flue gas outlets to the
stack;
⚫
fix the sensor on the boiler in a point specially designed for that purpose or on an
unshielded outlet pipe of the CH boiler (as close to the boiler as possible);
⚫
using hose clip tighten the sensor to the pipe and cover it with thermal insulation.
c)
connecting the power cable to the pump:
⚫
connect the yellow or yellow-green wire (protective cable) with the terminal (
);
⚫
connect the blue wire to the terminal (N);
⚫
connect the brown wire to the terminal (L);

terminal boxes.
f)
connecting the controller:
⚫
after securing the cables against any accidental rupture,
connect the power cable
to a 230 V / 50 Hz socket with an earthing pin.
g) connecting the thermal protection
⚫
fix a bimetallic circuit breaker along with a temperature sensor on the boiler in a point
specially designed for that purpose or on an unshielded outlet pipe of the CH boiler (as
close to the boiler as possible);
⚫
put the bimetallic circuit breaker against the pipe
(the side without 90°C label
facing the pipe)
, using hose clips fix it tight to the pipe and cover with thermal
insulation.
