When this type of regulator is selected, the valve works according to <room
temperature reduction> parameter. Activation of this regulator enables the
user to view the current temperature of the CH boiler, water boiler and the
valves. This regulator should be plugged to RJ (telephone-type) socket of the
ST-408N controller using a four-core cable with appropriate pins (to the
socket at the back of the controller)

TECH regulator algorithm
When this type of regulator is selected, the valve works according to <change
in valve set temp.> and <room temperature difference> parameters.
Activation of this regulator enables the user to view the current temperature of
the CH boiler, water boiler and the valves. This regulator should be plugged to
RJ (telephone-type) socket of the ST-408N controller using a four-core cable
with appropriate pins (to the socket at the back of the controller)

Standard regulator 1, 2 and 3
When this type of two-state regulator is selected, the valve works according to
<room temperature reduction> parameter. This regulator should be connected
to the controller in the place labelled Regulator pokojowy 1,2 lub 3 using a
two-core cable.
IV.d.7) Weather-based control
For the function of weather control to be active, the external sensor mustn't be
exposed to sunlight or influenced by the weather conditions. After it is installed in an
appropriate place, weather control function needs to be activated in the controller
menu.
For the valve to operate correctly, the user defines the set temperature
(behind the valve) for 4 intermediate external temperatures:
TEMP. FOR -20
TEMP. FOR-10
TEMP. FOR 0
TEMP. FOR10
Heating curve – it is a curve according to which the set controller
temperature is determined, on the basis of external temperature. In our
controller, this curve is constructed on the basis of four points of set
temperatures for respective values of external temperatures. Set temperatures
must be determined for the following external temperatures: -20ºC,-10ºC, 0ºC and
10ºC.
The more points constructing the curve, the greater its accuracy, which allows
its flexible shaping. In our opinion, four points seem a very good compromise
ensuring decent accuracy and easiness of setting the course of this curve.
In our controller:
XA = -20ºC,
XC = 0ºC,
XB = -10ºC,
XD = 10ºC,
