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 configuration 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.
