VI.JV.R1.02

Electronic programmable room thermostat 

The Akva Lux II TDP-F Type 144B2403 is equipped with a zone valve, 

and is thereby prepared for fitting of a thermal actuator TWA-A, 

which enables connection to an 

electronic programmable room 

thermostat

For Akva Lux II TDP-F Types 144B2434 and 004U8089 zone valve and 

thermal actuator are available as an option.

The thermal actuator is switched on by an external contact from 

the room thermostat, and starts to open or close the valve. The ac-

tuating movement is achieved by means of an electrically heated 

expansion element. When the heating current is switched off, the 

actuator shuts or opens the valve.

The actuator is equipped with a visual position indicator to show 

the open or closed position of the valve.

If the substation is connected to a room thermostat the tempera-

ture is controlled by the room thermostat and radiator thermostats. 

Please note that the room thermostat keeps the temperature at a 

constant level in the whole apartment according to the set room 

parameters.

Consult additional maintenance instructions for room thermostat 

for further information. It is recommended to avoid fully opened 

thermostats on some radiators and fully shut-off on others. Higher 

temperature at the top and lower temperature at the bottom part 

of radiators means that the system operation is correct. To keep cor-

rect temperature and friendly microclimate for human beings in the 

apartment, it is recommended to ensure regular airing in rooms.

Thermal actuator TWA-A

Please note

: Before mounting of 

the electronic room thermostat, an 

thermal actuator TWA-A for ON/OFF 

controls of the heating system must 

be mounted on the zone valve.

TWA-A

For Danfoss RA valves

TWA-V

For Danfoss RAV/VMT valves

TWA-L

For Danfoss RAVL valves

TWA-K

For Heimeier/MNG/Oventrop 

valves with M30 × 1.5 connection,

generally as per attached drawing.

Other valves must be verified 

individually to ensure correct 

valve closing measurement and 

valve top geometry.

TWA-D

For Danfoss RTD valves
