*Sensor’s function may differ from the drawing
depending on selected scheme
16.2.5. Temperature sensor installation
Temperature sensors are equipped with
brass coat with diameter of 6mm and 50mm
long. They should be installed possibly close to
the temperature measurement point. The sensors
must be installed so that the brass coat is
thermally insulated from the environment.
The collector temperature sensor must be
located in the collector tube possibly deep, as
this is conditional for correct measurement.
If you need mount your sensor on pipe surface
(e.g. CH temp. measurement), then the sensor
coat must be attached using a brace, and the
jointing point to insulate e.g. with foam or other
insulating material, so that there is sufficient
temperature convection to the sensor.

16.2.6. Room temperature sensor
installation
The room temperature sensor type CT7 is
only used in the M scheme.
Controller cooperate with CT7 type room
temperature sensor. The sensor should be
connected to the
T3 input. Use a cable with a
cross-section of at least 0,25mm
2
to connect
sensor. Recommended cross-section is 0,5mm
2
.
Cable should not be longer than 20m .
Fig. 16.10 Cable socket and how to close the CT7
sensor housing
Sensor cables should be separated from power
cables (~230V). If not, incorrect temperature
readings can occur. Minimum distance between
sensor cables and power cables should be at
least 100mm.
In order to guarantee a maximum operation
efficiency
of the regulator, follow the
recommendations concerning a place of sensor
assembly:

Sensor should be assembled on a height
app. 1,5m over the floor level.

Avoid places which are strongly sunlit,
close to heating devices, in direct vicinity
of
doors and windows, where a
