room temperature. The return flow temperature
of the surface heating (measured by the remote
sensor) will be limited. The heater will be switched
on when the room temperature drops below the
current set-point.
In case of function
„Min Return Temp“
(H3) it will be
heated if the return temperature drops below the set
min-value. This is even when the room temperature
is too high (permanent floor temperature).
In case of function
„Max Return Temp“
(H3) heating
will be stopped if the return temperature exceeds
the set max-value. This is even when the room
temperature is too low.
Adjusting the maximum return temperature
„Max
Return Temp“
(H3) is absolutely necessary for re-
liable and troublefree operation because
otherwise
there might be damage to the floor structure!
Caution:
The maximum permissible supply flow tempera-
ture of the surface heating must be respected.

Note for arranging the regulating box in rooms
with showers or bathtubs:
1
The regulation box has to be arranged outside of
the zones 0, 1 and 2 in conformity with DIN VDE
0100-701 to prevent contact with splashing water.
Prepare the insulation box for the mounting by
inserting the fixing clips from the backside into
the drill holes at the corner points of the box and
securing them with the supplied screws so that
they cannot fall out.
2
The fixing clips are arranged crossed-over. The
clips can also be exchanged in any way depending
upon the construction site situation. The clips can
be moved horizontally in order to create a depth
compensation as long as the screws have not been
finally fixed.
The box is positioned to fixing clips on the rough
wall in a sufficiently large wall recess (approx. 180 x
230 mm). Please pay attention to the mark of the
protective cap to the surface of the finished wall
in order to adjust the box optimally in the depth.
Afterwards fix the box with the adjusting screws.
Before the connection of the pipings, the notches
on the box are to be formed by breaking out the
walls at the corresponding positions.
