Operating Instructions
Room thermostat Touch 2
Item No. 2480785
Intended use
The heating thermostat is intended for temperature control in conjunction with
an electric heater.
The product operates under the mains voltage; the mains operated load can be
connected and switched on or off by temperature control.
It is equipped with an internal and external sensor (probe). The external
sensor can be used to measure the temperature in a different location to the
thermostat, such as on the floor with an electric floor heating system.
A keypad lock can be activated to protect against the incorrect operation, and
a backup (non-removable) capacitor supplied with the unit serves to preserve
data in case of power failure.
This device has an IP20 ingress protection rating and is suitable for dry
rooms and indoor use.
Do not use it outdoors. Contact with moisture, e.g. in bathrooms, must be
avoided under all circumstances.
For safety and approval purposes, you must not rebuild and/or modify this
product. If you use the product for purposes other than those described above,
the product may be damaged. In addition, improper use can result in short
circuits, fires, electric shocks, or other hazards. Read the instructions
carefully and store them in a safe place. Make this product available to third
parties only together with its operating instructions.
This product complies with the statutory national and European requirements.

---|---
a) General information
-
The device is not a toy. Keep it out of the reach of children and pets.
-
Do not leave packaging material lying around carelessly. This may become dangerous playing material for children.
-
Protect the appliance from extreme temperatures, direct sunlight, strong jolts, high humidity, moisture, flammable gases, steam, and solvents.
-
Do not place the product under any mechanical stress.
-
If it is no longer possible to operate the product safely, take it out of operation and protect it from any accidental use. The safe operation can no longer be guaranteed if the product:
– is visibly damaged,
– is no longer working properly,
– has been stored for extended periods in poor ambient conditions or
– has been subjected to any serious transport-related stresses. -
Please handle the product carefully. Jolts, impacts, or a fall even from a low height can damage the product.
-
Consult an expert when in doubt about the operation, safety, or connection of the appliance.
-
If you have questions that remain unanswered by these operating instructions, contact our technical support service or other technical personnel.
b) Installation/connection Caution, safety hazard!
The product should only be installed by people with relevant electrical
knowledge and experience! *)
If it is not installed properly, you risk:
- your own life
- the life of the user of the electrical device
If it is not installed properly, you risk severe damage to property, e.g. by
fire.
You face the risk of personal liability for personal injury and material
damage.
Always consult an electrician!
*) Technical knowledge required to perform the installation:
For the installation, the following specialist knowledge is required in
particular:
- The “Five safety rules”: Disconnect from the mains; protect against accidental switch-on; ensure there is no voltage; earth and short-circuit; cover or protect adjacent live parts
- Use of suitable tools, measuring devices, and personal protective equipment, where necessary
- Analysis of measurement results
- Use of electrical installation materials to meet the requirements for disconnection
- IP protection ratings
- Installation of electrical installation materials
- Type of power supply (TN system, IT system, TT system) and the corresponding connection criteria (classic earthing, protective earthing, necessary additional measures, etc.)
If you are not a professional, do not do it yourself, have it performed by a specialist.
Further warnings:
- The construction of the product corresponds to the protection-class II (double or reinforced isolation). Ensure that the insulation of the housing is neither damaged nor destroyed.
- During installation, all poles must be disconnected from the mains voltage, e.g., via RCD. There must be an appropriately rated fuse or circuit breaker between the RCD and the product.
- The device must be voltage-free during installation and connection. Furthermore, turn off the automatic circuit breaker and the earth leakage circuit breaker to disconnect all the poles from the mains voltage. Secure it against unauthorized reconnection, e.g., with a warning sign. Check to make sure there is no voltage with a suitable measuring instrument (e.g., a digital multimeter).
- Never connect the product to the power supply immediately after it has been transferred from a cold room into a warm one (e.g., during transport). The condensation that forms might destroy the device. Moreover, there is a danger of electric shock!
- Allow the product to reach room temperature. Wait until the condensation has evaporated. This might take several hours. Only after this, should it be installed, connected to the mains supply, and put into use.
- Do not use the product in rooms with adverse environmental conditions, where combustible gases, vapors, or dust are or may be present! There is a danger of explosion!
c) Ingress protection
- This device has an IP20 ingress protection rating and is suitable for dry rooms only.
- There is protection against touching live components and ingress from foreign particles >12.5 mm.
- There is no protection against water, combustible gases, and vapors.
Installation
-
To remove the front panel, slide the front part with the display upwards (A). The two parts are connected by a ribbon cable (B).
The ribbon cable can be disconnected if needed. Be careful not to damage it. -
On the back of the wall thermostat (C) there are 6 terminals for connecting the:
– The main power supply
– Electrical load
– External NTC temperature sensor
• Connect the main power supply to the corresponding inputs 3 and 4.
• Connect the load (e.g., an electric radiator or electric floor heating) to corresponding outputs 1 and 2.
If the load requires a protective earth connection it must be connected separately.
The thermostat complies with protection class II and does not by itself require a protective earth connection. -
If using an external temperature sensor (probe), it should be connected to terminals 5 and 6 (C). There is no polarity so it does not matter which way you connect the wires.
When laying out the connection cable, make sure it is protected from sharp edges.
Never fasten the connection cable with nails, screws, or similar. -
Insert the wall thermostat into the flush-mounted/ surface-mounted box and fasten it using the included screws (D).
**** Make sure that the cables are not damaged when inserting the wall thermostat into the flush-mounted/surface-mounted box. -
Reconnect the ribbon cable if needed. It can only be connected one way, do not use force when plugging in!
-
Align the front panel (E) and push it down (F). It should lock into place.
-
Switch on the voltage supply.
-
The wall thermostat is now operational.
