2. Area of Application
Heating systems
For combined radiator-surface heatings the RTL-TH
DIGITAL Regulation Box is used for the room tempe-
rature-dependent regulation of the surface heating
while limiting the return flow temperature.
3. Technical Description
The regulation box consists of a wall insulation
box with a pre-mounted valve module, an electrothermal actuator, a protective cap, an air vent plug,
a flowmeter for measuring and regulating the volume flow and a wall cover.
The valve module is provided with a 3/4“ male
thread (Euro taper) for a connection via Simplex
compression adapter on the pipe side.
The valve is comfortable activated with the room
temperature controller RTL-TH DIGITAL.
This programmable temperature controller allows
programming switching events (up to 9 per day) and
temperatures according to personal needs. Aer
installation the device automatically shows the time
of day and the room temperature.
In AUTO mode, the heater will be automatically activated according to programmed time and temperature. Program 1 is the default pre-set program (see 8.
room temperature controller).
Room temperature will be regulated based on the
Work on heating systems must only be done by qualified
professional personnel and in accordance with the

1. Features
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 reliable and troublefree operation because otherwise
there might be damage to the floor structure!
Caution:
The maximum permissible supply flow temperature of the surface heating must be respected.

Note for arranging the regulating box in rooms
with showers or bathtubs:
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.
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 suiciently 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.
Aerwards 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.
2 of 12
Please pay attention to a tension-free installation
and the correct flow direction (supply flow le
- see arrow mark!) when connecting the piping
system. Reversely mounted connections cause
valve noises and a bad control behaviour.
Tension-free compression connection must also
be guaranteed when the system is in operation,
i.e. expansion loops or appropriate securing of
the pipeline must be provided.
Before starting the plaster and wall covering
works, the box is to be covered with a protective
cap. The remaining space between the box and
the wall notch can be filled with PU foam.

Aer finishing the wall covering works, the final
mounting is done by removing the protective cap
and putting on the wall cover.

6. Ventilation
The system can be ventilated as necessary using the
ventilation valve installed.
7. Flowmeter
Flowmeter regulating valve for the regulating the volume flow. The upper part of the valve consists of a
valve cone with a rising spindle and a handwheel for
adjustment. The sight glass is installed in the hand
wheel where the flow can be read directly in L/min
on the printed scale depending upon the position of
indicator unit. The adjustment on the flowmeter can
be blocked by the delivered stop cap and sealed if
desired.
Volume Flow Regulation
Remove the lock cap. The control is performed by
turning the black handwheel whereby the valve
cone will be turned down when turning to the right.
The volume flow will decrease until reaching the
complete blocking. The opening of the valve is performed by turning it in the opposite direction.
Cleaning Flowmeter
The sight glass and measuring spring can be removed for maintenance and cleaned, even at full
system pressure. In order to do so, hold the black
5 of 12
hand wheel firmly and turn to the le to remove the
sight glass.
Do not use any tools when removing the sight
glass! Risk of breakage!
Unscrew the sight glass quickly and removed, together with the spring located inside. The flowmeter
locks automatically once the sight glass and spring
have been removed. In this condition, there may
be some slight water loss from the valve. Clean the
sight glass quickly and screw together again in the
opposite order.

Troubleshooting
1. It is getting warm too late: a. Are clock and program events set correctly?
b. Is the „Optimum Start“ feature switched on? (see H7)
Did the controller had enough time (serveral days) to
adapt to the room’s characteristics?
c. Is an automatic change between Summer and Winter time
activated? (see G5)
2. The controller does not accept any changes: Is access protection switched on? (see G6)
3. The range of temperature setting is limited: Are temperature limits set (see G7)
4. Temperature display doesn‘t change: Is display of set-temperature activated ? (see G10)
5. The room heats up too slow: The return temperature may be limited from the controller‘s
max-limiter (see H3).
6. The room becomes too warm: The return temperature may be limited from the controller‘s
Min-limiter. (see H3)
