Controller assembly
10.1
General requirements
The controller should be installed by a
qualified installer in accordance with
currently valid standards and regulations.
Prior to installing the controller make sure
that it will properly cooperate with hydraulic
and electrical system. It is recommended to
install an output module inside boiler room
first. During the assembly, control panel
should be electrically connected to the output
module and left in the boiler room. In will be
used to verify if electrical connections are
proper. After verification, the control panel
can be moved to a residential room.
10.2
Output module assembly
The regulator casing does not provide dust
and water immunity. In order to provide the
protection from these factors the regulator
should be enclosed with a proper casing.
The regulator is to be enclosed – which
means the regulator should be screwed on to
the flat horizontal or vertical surface (e.g.
room wall). To screw on the regulator use
mounting holes and proper screws. Location
and spacing of mounting holes are shown in
the picture below. The regulator must not be
used as a free-standing device.
Arrangement and spacing of the mounting holes in the
housing.
After installation make sure that the device is
properly mounted and it is impossible to
detach it from the mounting surface.
The regulator casing provides the IP20
protection rating. The casing on the
connectors cover side provides IP00 rating,
and because of that connectors must be
unconditionally covered with the cover.
If there is a need to gain an access to the
terminals side, it is a must to disconnect the
mains voltage and make sure there is no
dangerous voltage on regulator terminals.
10.3
Temperature sensors assembly
The regulator is compatible only with CT4,
CT-10, CT6-P, CT6-W sensors. The use of
other sensors is prohibited.
At least one heating circuit temperature
sensor and one external temperature sensor
(weather sensor) are necessary to activate
the controller.
The controller is equipped with
various types of temperature
sensors.
Connecting
an
inappropriate sensor will cause
incorrect
operation
of
the
controller.
Sensors for heating circuits
Direct heating circuit sensor (H1-S) should
be installed in a hydraulic coupling. If there
is no hydraulic coupling in the system, it can
be fixed to a supplying pipe coming out of
the heat source (boiler).
Assemble the adjustable heating circuit
sensor (H2-S or H3-S) on a pipe after the
heating circuit pump. The temperature
sensors should be installed in a sleeve
located in stream of running water in pipe,
but also it can be installed on the pipe, on
condition that it is thermally isolated from
the pipe.
Mounting temperature sensor: 1 - pipe, 2 – clamps, 3 -
thermal insulation, 4 - temperature sensor
.
Insulate sensors affixed to the external
surface of the pipe with the use of thermal
insulation covering the sensor together with
the pipe.
