TVV20, valve + SD20, actuator
Another water regulation alternative with
thermostat controlled heat supply, without the
option of adjusting or stopping the water flow.
Pipe dimension of TVV20 is DN20 (
3
/
4
”).
Consisting parts:
• TVV20, 2-way regulation valve
Pressure class PN16, maximum pressure 2 MPa
(20 Bar), maximum pressure drop for TVV20 is
100 kPa (1,0 Bar). The kv-value is adjustable in
three stages:
TVV20
kv 1,6 kv 2,5 kv 3,5
• SD20, actuator on/off 230V~
The heat supply to SW02 is controlled by a room
thermostat. Works on/off. The time span between
closed and open prevents sudden pressure
changes in the pipe system. Protection class:
IP40.
Room thermostats
(see accessories on page 2)
Regulates actuator SD20 to open/close the valve
when there is a demand for heat. The room
thermostat can also be used to start/stop the fan
motor, see wiring diagrams.
KUR, time switch
Digital time switch to start/stop the fan, change
between high/low air flow or for night time
reduction via external thermostat. With night
time reduction, energy savings are obtained
through a lower temperature for a specified time
such as nights and weekends. 24-hour or week
function. Protection class: IP55.
SWFT02, basic filter
SW02 can be equipped with a filter. The filter is
mounted in front of the water coil (pushed down
