Operating Instructions Floor heating controller

Two electronic control panel components: one with a dial and knob, the other showing an internal circuit board (no visible text or symbols)

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 - 1.

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 ^ (number on dial = 4). This means that the temperature in the floor e.g. during the night can drop down to 29 ^ without your heating switching itself on.

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.

① 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.
① When working on the load circuit, the mains voltage must be disconnected in principle.
① 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.

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)):
