Akva Lux II TDP-F
Electronic programmable room thermostat
The Akva Lux II TDP-F types 004U8264 and 004U8044 are equipped
with a zone valve, and thereby prepared for fitting of a thermal
actuator TWA-A, which enables connection to an
electronic pro-
grammable room thermostat
.
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.
11.0 Flow regulator
A flow regulator is a control device, which, irrespectively of mains pres-
sure, maintains the designated flow rate. This means that the flow reg-
ulator automatically equalizes all changes in pressure within a large
pressure range (normally 1 to 10 bar), and thereby ensures a constant.
flow regardless of water supply pressure.
Even at low pressures the required flow is obtained. At high pres-
sures no unnecesssary water is wasted; in fact much water and en-
ergy can be saved by using flow regulators.
