The unit may only be opened by an electrician and installed according to the circuit diagram on the unit or in these instructions. Observe existing safety instructions.
To satisfy the requirements of protection class II, corresponding installation measures are required.
This independently installable electronic device is exclusively for controlling the temperature in dry, enclosed rooms with normal surroundings.
This device is in conformance with EN 60730 and functions according to operating mode 1C.
Damage to the device, fire, or other hazards may arise if these instructions are not followed.
These instructions are a component part of the product and must remain with the end customer.

Product characteristics
Fig. 2: Default display
Four buttons below the display are used to operate the temperature controller (Fig. 2, items (13) to (16)). In the menu, you can activate operating modes, adapt programs and make settings. If a button is not pressed for more than three minutes, the unit automatically switches back to the previous function and the default display (Fig. 2). Program 1 and AUTO mode are the preselected defaults; see “Default programs” and “Modes and setting menus (overview 1)”.
Programming when the controls are removed
The unit can also be programmed when the controls are removed. The current temperature is not displayed, the “heating mode” display flashes, and the display is not illuminated. If a button is not pressed for more than three minutes, the display goes dark.
Display information on the current mode
To go to the default display when the controls are removed and the display is dark, press any button.
Selecting modes and setting menus
Manually adapting the target temperature
You can always adapt the target temperature in modes AUTO, MAN, and TIMER.
Turning off the controls
The controller offers three default time/temperature programs (full-day settings). These full-day settings depend on the selected heating mode (installer settings, H1) and can be selected by the user and adapted to individual heating preferences (user settings, G1 and G2). The factory setting is program 1.
The default time/temperature programs are illustrated in the following in sections in graphs and tables. A specific example is used (room temperature controller) for program 1 to explain the full-day settings.

Select program (G1)
The factory setting is program 1.
The device is in the default display.
Press the M button.
The help text “MENU…” appears at the bottom edge of the display.
Adapting the program (G2)
The default programs can be adapted to individual heating comfort. A maximum of 9 switching times/intervals per day is possible. All adaptations affect the active program. When you switch to the new program, the adaptations are not saved; that is, any adaptations made to a default program must be reconfigured.
The desired program is active (G1), and G1 – PROGRAM SELECT ONE appears.
The numbers correspond as follows: 1 Monday, 2 Tuesday… 7 Sunday.
With the exception of individual weekdays, switching times can also be set for blocks of days 1-5, 6-7, 1-7.
If needed, additional temperatures and switching times can be set using the same procedure. The number of the switching interval is displayed in the bottom line of the display in front of the switching times. The respective end time in the display becomes the start time of the next interval. Each switching time can be decreased to the previous time or to 00:00 and increased to a maximum of 23:50. If ->>> flashes in the display, the following switching time falls within the next weekday.
If all 9 switching times of the day are already assigned, the program automatically jumps to the next day of the week. You can delete a switching interval indirectly by increasing the previous interval. Repeatedly press
Modes and setting menus (overview 1).
To follow is an overview of the modes and setting menus within the main menu.

Installation and electrical connection
DANGER!
Electric shock from touching live parts.
Electric shock can be fatal.
Before working on the device, disconnect the connecting lines and cover the surrounding live parts.
The controller should be installed at a location in the room that is easily accessible for use.
When using the internal temperature sensor, the chosen installation site should:
The terminals (18) before the power supply and switching current are designed for solid or flexible lines with a cross-section of 1 to 2,5 mm2.
Only install the temperature controller in non-conductive plastic flush-mounted boxes with a diameter of 60 mm.
An external remote sensor is necessary for the modes “Floor temperature controller” and “Room temperature controller with limiter”. The remote sensor line carries mains voltage and can be extended to 50 m with appropriate wires. In order to prevent signal faults, do not run the remote sensor line together with the power lines. It is recommendable to run the remote sensor in ducting.
CAUTION!
The heating system will malfunction if the controls are incorrectly set.
This can damage the heating system.
Only a technician may adjust the settings.
Set the heating mode when starting the controller.
ROOM is the default. When switching the heating mode, all of the user and installer settings are reset to the default.
Additional settings are available under “Installer settings”.
