VNT20 is a fan speed regulator integrated with a room thermostat. It features automatic fan speed
regulation in function of the temperature. PI regulator automatically reduces the device airflow, and thus
energy consumption and noise level, when the set room temperature is being approached
During control in AUTO mode the speed is regulated automatically and smoothly on the basis of a signal
from the temperature sensor. Change of the fan airflow results in changing the heat capacity in function of
temperature difference. Either a separate valve with actuator for every heater or one valve for all heaters
may be used in this mode. In AUTO mode it is not necessary to use valves. In this case the heating
medium is regulated by the boiler automatic system. The speed regulation knob is inactive in AUTO mode
(setting it to minimum switches off the fan control). The minimum speed in AUTO mode may be changed
in the range of 0-60% (default setting to 30%).
During control in MANUAL mode the room thermostat and the speed controller operate independently.
The room thermostat controls the operation of the SRV2, SRV3d or SRS valve with actuator, while the
speed controller controls the fan speed. The room temperature is thus controlled by the thermostat which
opens and closes the valve depending on the thermostat setting. In this case the fan is operating at a
constant speed adjusted by the user for the entire time of operation of the device. This mode of operation
is called „continuous”. Operation in „thermostatic” mode consists in that after reaching the set room
temperature the device is switched off completely (the valve is closed and the fan is switched off).
Setting the speed regulation knob to „standby” position in MANUAL control mode results in switching off
the fan while the thermostat continues to control the valves operation. This is a form of protection of the
device and the system against freezing of the medium.
The VNT20 integrated control panel allows (through the R10 signal distributor) simultaneous operation of
up to 10 devices.
In order to increase the general safety, the fan connection is executed in the junction box located
outside on the cable.

VNT20 tai su patalpos termostatu integruotas ventiliatoriaus sukimosi grei č io reguliatorius. Temperat ū ros
funkcijoje yra automatinis ventiliatoriaus grei č io reguliavimas. Temperat ū rai art ÷ jant prie patalpoje
nustatytos temperat ū ros, PI reguliatorius automatiškai mažina našum ą , o vadinasi ir į renginio
triukšmingum ą bei energijos sunaudojim ą .
AUTO režime sukimosi greitis yra reguliuojamas savaime, tolygiai pagal signal ą , kur į duoda temperat ū ros
daviklis. Kei č iant ventiliatoriaus našum ą , kei č iasi šildymo galia temperat ū r ų skirtumo funkcijoje. Šiame
režime galima pasinaudoti atskiru vožtuvu su servovarikliu kiekvienam šildytuvui arba vienu vožtuvu,
skirtu visiems šildytuvams. AUTO režime neb
ū tina naudoti SRV2d vožtuv ų . Tokiu atveju vandens
šildym ą reguliuoja katilo automatika. Sukimosi reguliavimo ranken ÷ l ÷ AUTO režime yra neaktyvi
(nusta č ius ant minimumo, išsijungia ventiliatoriaus valdymas). Minimalius apsisukimus AUTO režime
galima keisti diapazone 0-60% (gamyklinis nustatymas ant 30%).
MANUAL valdymo režime patalpos termostatas ir grei
č io reguliatorius dirba nepriklausomai vienas nuo
kito. Patalpos termostatas valdo SRV2d, SRV3d abra SRS vožtuvo su servovarikliu darb ą , tuo tarpu
grei č io reguliatorius valdo DSS2e ventiliatoriaus sukimosi reguliatori ų . Tad temperat ū r ą patalpose
kontroliuoja termostatas, kuris atidaro ir uždaro vožtuv ą , priklausomai nuo termostato nustatymo. Šiuo
atveju ventiliatorius dirba pastoviu, vartotojo nustatytu sukimosi grei č iu per vis ą į renginio darbo laik ą . Tok į
darb ą vadiname „pastoviu“. Darbas „termostatiniu“ režimu remiasi tuo, kad pasiekus nustatyt ą
temperat ū r ą patalpose, į renginys yra visiškai išjungiamas (užsidaro vožtuvas bei išsijungia ventiliatorius).
MANUAL valdymo režime, nusta č ius sukimosi grei č io reguliavimo ranken ÷ l ę į „bud ÷ jimo“ pad ÷ t į ,
ventiliatorius išsijungia, o tolimesn į vožtuv ų darb ą kontroliuoja termostatas. Taip apsaugome į rengin į ir
instaliacij ą nuo vandens sušalimo.
VNT20 integruoto valdymo panelio d ÷ ka (R10 skirstytuvo pagalba), tuo pa č iu metu galima aptarnauti iki
10 į rengini ų .
Kad padidintume saugum ą , ventiliatori ų reikia pajungti iš kabelio išvestoje pajungimo kabelin ÷ je
movoje
