  Description of functions
  The programmable temperature controller automatically controls the room or floor temperature depending on the time and day of the week. The automated program can be interrupted at any time by manual entries.
  The temperature controller has three selectable programs for heating which can be adapted to your individual comfort. The controller is equipped with an internal sensor for measuring the room temperature. In addition, an external remote sensor can be connected, for example, to measure the floor temperature. The temperature controller compares the measured temperature with set values. If the temperature falls below the current setting, the heating system is turned on.
  The control method depends on the type of heating and is determined by the installer:
• Room temperature controller: The heating is turned on when the room temperature falls below the set target temperature (measured with an internal sensor or external remote sensor).
• Floor temperature controller: The floor heating is turned on when the floor temperature falls below the set target temperature (measured using an external remote sensor).
• Room temperature controller with a limiter (in conjunction with floor heaters):
  The room temperature is measured and regulated using the internal sensor. An additional external remote sensor is connected to measure the floor temperature, and a target temperature range for the floor is set. The room temperature control is deactivated when the floor temperature is outside of this range. If the temperature falls below this range, the heater is turned on, and if the temperature is above this range, the heater is turned off independent of the current room temperature.

Basic information

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.

• Press in the default display.
  Information on the current mode/setting is displayed in the form of a marquee.
• Return to the default display by pressing .

Selecting modes and setting menus

• Press in the default display.
  MENU briefly appears in the function display (8). A help text as a marquee appears at the bottom edge of the display.
  Use the + / – buttons to switch to the desired mode/setting.
• Select the desired mode/setting by pressing .
  Another menu opens depending on the mode/setting.
  • Go back to the last display/setting by pressing .
• Return to the default display by pressingseveral times.

Manually adapting the target temperature
You can always adapt the target temperature in modes AUTO, MAN, and TIMER.

• In the default display, press + or -.
  The current target temperature flashes.
• Set the desired temperature by pressing + / -.
• Accept the displayed temperature by pressing .
  The device returns to the default display.

Turning off the controls

• In the default display, press thebutton for 10 seconds.
• First “MENU” appears in the display. After 10 seconds, the device switches to the default display, and “OFF” appears.
• Turn the controls back on by selecting a mode.

Default programs

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.

Information for electrically skilled persons

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.

Installation site

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:

• Enable free circulation of air
• Not be in a draft (such as an open window or doors)
• Not be located behind curtains, cabinets, shelves, etc.
• Not be exposed to direct sunlight
• Not be directly influenced by sources of heat
• Not be adjacent to external walls
• Be 1.5 m above the floor.
  Connecting and installing the controller.
• Remove the controls (1) from insert (7).
• Remove a maximum of 8 mm of insulation from the connecting lines.

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.

• Connect the controller according to the connection diagram (Fig. 4).
• If necessary, connect an external remote sensor (20) (see “Connecting the external remote sensor”).

Only install the temperature controller in non-conductive plastic flush-mounted boxes with a diameter of 60 mm.

• Align the insert (7) in the receptacle (22).
• Fix the insert with fastening screws (23). Install the insert so that the plastic tongue (21) functions as insulation against the fastening screw (Fig. 5).
• Mount the design frame (5) and secure it by attaching the controls (1).

Connecting the remote sensor

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.

• Connect the remote sensor according to the connection diagram (Fig. 4, item (20)).
• When inserting and removing the connecting line using an appropriate tool, press the release button (Fig. 4/7, item (24)).
