Temperature Management Floor heating controller
Ref.-no.: ..FTR 231 ..
Operating Instructions
Floor heating controller
1. Area of application
Used in domestic electrical installations to regulate electrical floor heating
systems and temperature control systems.
2. Function
The floor heating controller consists of two parts:
• Control unit for setting the required floor temperature
• Remote sensor in the floor for monitoring the set temperature
Control unit:
Using the setting knob, set the required temperature for your floor. The
numbers  – 6 on the knob correspond to a temperature range of 10 – 50
°C.
Note the setting instructions from the manufacturer of your floor heating
system.
If the temperature in the floor falls below the temperature you have set,
the control unit requests heat; this state is displayed by the red LED
above the setting knob. You can therefore see if your heating is using
energy.
A range restriction can also be carried out in the setting knob.
The operating state of your floor heating is switched on or off with the
mains switch 0 – I.
You also have the option of programming a temperature reduction via an
external time switch e.g. during the night.
If you have installed this type of time switch, the temperature reduction is
indicated by the green LED above the setting knob. The temperature
reduction is approx. 5 °C.
Example: The temperature set by you on the control unit is 34 °C
(number on dial = 4). This means that the temperature in the floor e.g.
during the night can drop down to 29 °C without your heating switching
itself on.

Ref.-no.: ..FTR 231 ..
Sensor:
The sensor is to be installed in the floor. It monitors the floor temperature
set on the control unit and issues commands to switch the floor heating
on and off.
Safety instructions
Electrical equipment may only be installed and fitted by qualified
electricians while observing the current accident prevention
regulations.
Non-observance of the safety warnings or installation instructions
may damage the device, cause fire or other hazards.
In the event of a fault, mains potential can be present at the sensor.
L The switch 0 – I on the control unit causes a singlepole disconnection
of the device from the mains and interrupts the circuit to the heating
resistor in the floor.
L When working on the load circuit, the mains voltage must be
disconnected in principle.
L When the sensor is interrupted, the relay contact is closed. If the
sensor experiences a short circuit, the relay contact is open.
3. Connection and installation
Control unit
Mount the control unit in a switch box in accordance with
DIN 49 073.
Notice! The device must always be mounted with its supporting
frame on top of the wallpaper!
• Carry out the electrical connection according to the wiring diagram
(Fig. (1)). Solid conductor cross-section: 1 to 2.5 mm2 No PE
conductor required. PE conductor is only used for looping through.
Protection class II can be achieved through appropriate installation
measures.

• Mount the control unit with the screws supplied.
• Place the center plate together with the frame on the flush insert.
The center plate must snap in place in the top left of the housing
base.
• Tighten the screw (A in Fig. (2)).
• Clip on the setting knob (B).

4. Sensor
The sensor must be laid in a conduit. It is thereby protected against damp
and can easily be replaced in the event of a repair.
Dimension drawing of remote sensor: Fig. (3).
5. Restricting the temperature setting range
The controller is set ex works to the maximum setting range of to 6.
There are 2 adjustment rings (Fig. (4)) in the setting knob which have a
setting range of 5 to 30 °C. When restricting the range, we ask you to
carry out the setting according to the diagram (Fig. (5)):
