Controller assembly
Environmental conditions
Due to fire risk it is forbidden to use the
controller in proximity of explosive gases or
dust. Moreover the controller cannot be used
in conditions of water steam condensation or
be exposed to effects of water.
Storage and transport
conditions
The controller cannot be exposed to
immediate effects of atmospheric conditions
i.e. rain or sunrays. Temperature of storage
and transport should be within scope
-
15…
+65
°C
.
Mounting requirements
Regulator should be installed by qualified and
authorized technician with observance of
applicable standards and regulations.
The manufacturer disclaims any liability for
damage caused by non-observance of
instructions specified in this manual.
Ambient temperature and temperature of
mounting base should be within the range of
0
…50˚C
.
Prior to installing the controller make sure that
it will properly cooperate with hydraulic and
electrical system.
Module installation
The regulator should be screwed on to the flat
horizontal or vertical surface (e.g. boiler
housing, 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.
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.
Temperature sensors assembly
The controller cooperates solely with
temperature sensor type CT-10, CT6-P, CT6-
W. 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.
Caution: 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 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 (from boiler).
Assemble the adjustable heating circuit
sensor on a pipe after the heating circuit
pump. Insulate sensors affixed to the
external surface of the pipe with the use of
thermal insulation covering the sensor
together with the pipe.
Mounting temperature sensor: 1 - pipe, 2
–
clamps, 3 -
thermal insulation, 4 - temperature sensor.
