Frequently Asked Questions - 75643030 HAGER

How do I install the Hager 75643030 thermostat?

Installation should be performed by a qualified electrician. The thermostat is typically wall-mounted. Connect the wires according to the wiring diagram in the manual. For battery-powered models, insert 2x AAA batteries.

How do I program the thermostat schedule?

Press the programming button PROG to enter schedule setting. Use the arrow buttons to set time and temperature for each period (e.g., morning, day, evening, night). Refer to the manual for detailed steps.

What type of batteries does it use?

The thermostat uses 2x AAA alkaline batteries. Replace them once a year or when the low battery indicator appears.

Can I use this thermostat with underfloor heating?

Yes, the Hager 75643030 is compatible with electric underfloor heating. Ensure the load does not exceed the relay rating (typically 16A). Consult a professional if unsure.

How do I reset the thermostat to factory settings?

Locate the reset button (usually under the flap or in the battery compartment). Press and hold for 5 seconds using a pointed object. This will erase all custom settings.

Why is my thermostat not turning on?

Check if batteries are inserted correctly or have power. Try fresh batteries. If mains-powered, verify the circuit breaker is on. If the display remains off, contact support.

How do I set the temperature manually?

Press the + or - buttons to adjust the temperature. The set temperature will be displayed. If in program mode, manual adjustment overrides the schedule until the next programmed change.

What does the frost protection symbol mean?

The frost protection mode maintains a minimum temperature (usually 5°C) to prevent pipes from freezing. This function can be enabled via the menu or automatically when the thermostat is in standby.

Can I lock the thermostat to prevent tampering?

Yes, many Hager thermostats have a key lock function. Press and hold the OK button for 5 seconds to lock/unlock. A lock icon will appear on the display.

Where can I find the user manual?

You can download the PDF manual for model 75643030 from notice-facile.com or the Hager official website. It contains installation, programming, and troubleshooting details.

System information

This device is a product of the KNX system and complies with the KNX directives. Detailed technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.

The function of this device depends upon the software. Detailed information on loadable software and attainable functionality as well as the software itself can be obtained from the manufacturer's product database. Planning, installation and commissioning of the device are carried out with the aid of KNX-certified software. The latest versions of product database and the technical descriptions are available on our website.

Intended use

• Operation of loads, e.g. light on/off, dimming, blinds up/down, brightness values, temperatures, calling up and saving light scenes, etc.
• Touch sensor: Installation in double flush-mounted appliance box according to DIN 49073
• Glass sensor: Glass sensor TS: Installation in double installation socket for glass sensor (see chapter 6.3. Accessories)

Product characteristics

• The pushbutton functions switching, dimming, controlling blinds, value transmitter, calling up moods, etc.
• Operation through touching the sensor buttons
• LED to display status or actuation
• Integrated room temperature sensor
• Room temperature control with setpoint value specification
• Display of room and setpoint temperature
• Display of external temperature; in conjunction with external KNX temperature sensor
• Display of day and time, in conjunction with KNX time encoder
• Temperature limitation for floor heating; in conjunction with external temperature sensor
• Integrated bus coupling unit

4 Operation

The operation of functions or electrical consumers can be set individual for each device. Two operating modes are used:

- Single button operation: Switching on or off or dimming brighter/darker, e.g. of lighting, takes place alternately when the same sensor button is pressed repeatedly.

- Two button operation:

Two sensor buttons next to each other form a function pair. Pressing the left button, for example, switches or dims lighting on or brighter, pressing the right one switches it off or makes it darker.

Operating a function or load

Consumers such as lighting, blinds, etc. are operated using the sensor buttons (2) and such operation depends on the programming of the device.

■ Press a sensor button.

The stored function is executed.

The actuation pulse is relative to the length of touch. Depending on the function, short and long actuations may trigger different actions, e.g. switching/dimming.

Operating modes and display icons

The device compares the current room temperature with the setpoint temperature and controls heating or cooling devices according to the current demand. The setpoint temperature depends on the current operating mode and can be changed by the user, depending on the programming. The operating modes and the current controller status are shown in the display.

5 Information for electrically skilled persons

DANGER!

Electrical shock on contact with live parts in the installation environment. Electrical shocks can be fatal.

Before working on the device, disconnect the power supply and cover up live parts in the working environment.

Mounting and connecting the Touch sensor

Figure 10

(5) Power supply connection
(6) Connection of wired floor temperature/remote sensors (accessories)
(7) KNX connection
(8) Programming LED
(9) Programming button

The device is installed by screwing the mounting frame to the appliance box or to the wall. Increased dismantling protection is achieved by securing the device on the bottom of the mounting frame using a retaining screw.

Use double flush-mounted box. Mounting on single flush-mounted boxes or surface-mounted boxes is not possible.

Bus voltage and an additional power supply are available at the installation location.

The yellow and white wire pair of the KNX bus line can be used to provide an additional power supply.

• Align the mounting frame (10) and screw it to the appliance box or the wall (Figure 11). Observe marking TOP = TOP. Use the enclosed set of screws.
  ■ Connect power supply to the terminal (5).
  ■ Connect the KNX bus voltage to the terminal (7).
  ■ Optional: Connect the external temperature sensor to the terminal (6).

i Programming button and LED are accessible only from the back of the device. If possible, load the physical address into the device before the final installation (see chapter 5.3. Commissioning).

■ Attach the device onto the mounting frame until it locks in place.
■ Tighten the retaining screw (11) on the bottom of the mounting frame. Use a Pozi-Drive screwdriver, size 0.

Preparing the Glass sensor for mounting on a smooth substrate

Figure 12

(12) Adhesion points for adhesive dots
(13) Retaining peg

The adhesive dots prevent the glass sensor from slipping when mounted on smooth surfaces.

■ Free the adhesion points for the adhesive dots on the rear side of the glass sensor (12) from impurities.
■ Remove the adhesive dots from the carrier film and stick them to the four adhesion points.
■ Free the substrate of impurities.
■ Before mounting the glass sensor, remove the protective film from the adhesive dots.

Before completing mounting, align the glass sensor and press it in the area of the adhesive dots, in order to fix it in place.

Mounting and connecting the Glass sensor

Use the double installation socket (accessory). Mounting on single concealed sockets is not possible.

Optional: For increased dismantling protection or to increase the shadow gap to the wall, use the enclosed mounting frame (10). For this, lock the mounting frame onto the device from behind. Observe marking TOP = TOP.

Bus voltage and an additional power supply are available at the installation location.

The yellow and white wire pair of the KNX bus line can be used to provide an additional power supply.
If necessary, measure the surface compensation. With deeper installation sockets, adjusting the retaining pegs (14) on the threaded pins (15) allows a surface compensation of up to 20 mm. Unscrew the retaining pegs (14) by the surface compensation x, so that they are at a distance of 15 mm + x from the socket for the threaded pins
When the mounting frame is used, the distance for the surface compensation is 20 mm + x from the socket for the threaded pins.
