The temperature regulator operation is
based on heating/regulation curve which we
obtain by means of choosing points inclu-
ding both the expected temperature and the
reference temperature, by choosing a ready
made curve or by changing options for room
regulation. The regulator preserves the tem-
perature with the heating source suitable for
the reference point (e.g outer or inner tem-
perature), chosen during conguration pha-
se. Regulation algorithm causes the heating
costs lower and the same gives full comfort of
room and weather regulation. The regulator
uses two sensors for proper operation. There
is also a possibility of extending its existing
connection cable up to 50 m with a cable sec-
tion of 0,2÷2,5 mm
2
. The reference tempera-
ture sensor can be replaced with a standard
resistor, which causes one sensor operation
as in the standard temperature regulation.
The regulator is a perfect solution in eve-
ry situation we want to be sure there was a
full factor ciculation e.g.: cooling systems or
heating systems, but also in situations where
suitable temperature difference is necessary
for preserving best conditions with maximum
low costs e.g.: hot water circulation. Repla-
cing one temperature sensor with a standard
resistor has the effect of constant regulation
around one point in accordance with the ad-
justed curve, close to the chosen points.
Replacing one temperature sensor with a
potentiometer with similar functions has the
effect of changing a universal regulator into a
standard temperature regulator with differen-
ce regulation possibility by means of curve
and hysterisis. It allows to control, e.g., the
heating source in such a way its temperature
is higher than the adjusted one including dif-
ference corresponding e.g. the ambient tem-
perature loss through windows, etc.

If the regulator is in the weather mode, the adjusted temperature values constitute a point of curve shift. The basic heating curve is based on 20 °C
comfort temperature. If the comfort temperature is adjusted to 25 °C the curve shifts to 5 °C up, however it goes 5 °C down if the comfort temperature is adjusted
to 15 °C. The antifreeze temperature switches off the regulator and switches on protection mode against freezing.

The reference temperature sensor should be mounted where hot water escapes
or at the top of a container (boiler) so it has the best contact with the temperature
of hot water for use. The expected temperature sensor should be mounted just
behind the last point of water drawing so it has the best contact with hot water for
use that returns to the container.

When the container reaches up to 40 ˚C the circulation pump should be switched
on manually for about 2 to 5 minutes; temperature should be measured in the point
where the expected temperature sensor is built - just behind the last water drawing
(economically recommended) or in the point just before returning to the container.
The container’s temperature should be increased by 10 ˚C and the whole experi-
ment should start from the beginning. All the points should be written down in a
table. An exemplary table is presented below.
