Danfoss Akva Lux II TDP-F Instructions For Installation And Use Manual page 14

Instructions for installation and use
Electronic programmable room thermostat (option)
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-o 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.
Safety valve
As optional equipment the substation can be equipped with a safety
valve set.
Please note that this is not part of the delivery and must be ordered
separately and mounted on site.
Always establish a blow-o pipe from the safety valve. The blow-o
pipe must be lead to a drain in accordance with applicable legislation.

For installation of safety set in Akva Lux II TDP-F with top connection
please contact your local Danfoss sales o ce.
10.0 Installation instructions, recirculation connection
If the household piping system features domestic hot water
recirculation, the substation must be connected to the recirculation
system. The circulation set for recirculation connection is not standard
equipment. The set must be purchased as extra equipment and
mounted on site.
We recommend establishing recirculation BEFORE mounting the
substation on the wall.
Connect the recirculation pipe from the xed household piping to
a circulation pipe mounted in the substation (please note that the
circulation pipe is not included in the optional circulation set, however,
please refer to the photoes to your right, which illustrate possible circula-
tion pipe connections).
You must always t a pump, non-return valve and safety valve to
the recirculation pipe, with ow direction towards the substation.
If a time-controlled pump is used, we recommend setting of the
circulation water temperature to approx. 35°C.
Please note that if the circulation pump (outside the substation) is
stopped for a protracted period, we recommend that the bypass
thermostat is shut o for the same period.
The circulation set and and control change possibility from bypass
to DHW recirculation will be described thoroughly on page 15.
