Functional description
Lowering mode (ECO)
In many areas of the building it makes sense for the temperature to be set
to a lower level at certain times rather than to heat permanently to the
comfort temperature. By connecting the input terminal Ø to 24 V, the
temperature is reduced by 4 °C. This should be controlled by a central clock.
Cooling mode
Modern heat pump systems often also provide the option of cooling rooms. In
cooling mode, it is possible to change the cooling temperature using the
control knob. Switching between heating and cooling mode is done via the
control knob or by wiring the input terminal “C” with 24 V.
Temperature drop detection
In the event of a sharp drop in temperature, e.g. after opening a window,
the system regulates to the frost protection temperature of 5 °C for a maximum
of 30 minutes. Pressing or turning the control knob cancels the operation.
Offset
This function allows the adjustment of the position of the control knob so
that it cor-responds to the room temperature. Thus, the indication of the
temperature via the control button is comparable in different rooms. An
adaptation of up to +/- 3 °C is possible.
Controller adaptation
Depending on the heating system, the control behaviour can be adjusted.
Pulse width modulated control (factory setting): Optimised for
electrothermal valve drives (see Technical data): The output is not
permanently actuated, but for a time period (pulse width) that depends on the
difference between setpoint and actual tem-perature. This method brings the
actual temperature gradually closer to the setpoint temperature.
Two-point control: The output remains switched on until the selected
setpoint temper-ature has been exceeded by 0.5 °C. The output will not be
switched on again until the setpoint value is undercut by 0.5 °C. Since most
heating systems respond very slowly, this type of control can entail
temperature overshooting.
Setting the valve type
Depending on the electrothermal valve drive used, an adaptation to the
valve type must be made. There are valve drives where the valve is opened
(deenergised opened) or closed (deenergised closed, factory setting) when no
supply voltage is applied.
Operation
Brief overview
| Function | Control knob | Status LED | LED colour |
|---|---|---|---|
| Change room temperature | … turn right or left | maximum 2 minutes | Red = |
heating mode Blue = cooling mode
Orange = frost protection (10 seconds)
Display operating mode| … press briefly| 10 seconds.| Red = heating mode Blue = cooling mode Orange = frost protection
Increasing or reducing the room temperature
- Turn the control knob to the right or left. If the setpoint temperature is not reached, the LED lights up for a maximum of 2 minutes in the colour of the current operating mode. In the middle position, the device regulates to approx. 20 °C setpoint temperature. The room temperature reached depends on the installation location of the device and the ambient conditions. The lowest setpoint temperature is approx. 5 °C and the highest setpoint temperature is approx. 30 °C.
Adjustment rings for temperature limit
Indication of the current operating mode
- Press the control knob briefly.
The LED lights up for 10 seconds in the colour of the current operating mode.
Orange = frost protection, blue = cooling mode, red = heating mode.
Switching off the temperature control
- Press the control knob for longer than 2 seconds until the LED lights up orange.
The device has switched to frost protection. The frost protection prevents the temperature from falling below 5 °C. Each time the control knob is turned, the LED lights up orange for 10 seconds.
- To activate the temperature control, press the control knob again for more than two seconds.
The device switches back to the previous operating mode. The LED lights up for
10 seconds.
Red = heating mode, blue = cooling mode.
Manual switching between heating and cooling mode
If 24 V is present at the input terminal C, manual switching to heating mode
is not possible.
- Press the control knob for longer than 4 seconds until the LED flashes red in active heating mode or flashes blue in cooling mode.
- Briefly press the control knob again to change the operating mode.
- Press the control knob for longer than one second until the LED lights up continuously to accept the displayed operating mode.
After 10 seconds without actuation, the displayed operating mode is
automatically adopted.
Red = heating mode, blue = cooling mode.
Information for electrically skilled persons
Selecting a suitable installation location.
- Recommended installation height: 1.50 m on interior walls
- Do not mount the device near sources of interference, such as ovens, refrigerators, draughts (e.g. next to the door) or direct sunlight. This affects the tem-perature measurement of the internal temperature sensor.
- Do not mount the device within shelf walls or behind curtains and similar covers
- Do not use the device in multiple combinations with heat-generating devices such as dimmers
DANGER!
Mortal danger of electric shock. Disconnect the device. Cover up live parts.
Connecting and fitting the device
-
Connect electrothermal valve drive (10) to insert (1) according to connection diagram .
-
Connection example of the insert
Observe the conductor cross-sections. -
Clampable conductor cross-section
-
Optionally, connect the lowering mode input Ø via a switching contact of a central clock (8).
If 24 V is applied to the input, the setpoint temperature is reduced by 4 °C.
- Optionally, connect the cooling input C via a switching contact of the heating system (9).
If 24 V is applied to input C, the cooling mode is active. If 24 V is switched off, the device automatically switches to heating mode.
After each switchover, the LED lights up for 10 seconds in the colour of the current operating mode.
- Fit device in appliance box; terminals must be at the bottom.
- Fit cover frame (2), central plate (4) and control knob (5).
- Switch on supply voltage.
Commissioning
Setting the control mode and valve type
Default setting:
- Pulse width modulated control (PWM)
- Valve type deenergised closed (NC)
This setting can be used with most heating systems without adaptation.
Changing the settings
- Press the control knob for longer than 20 seconds.
The LED flashes green for PWM control and green/blue for 2-point control.
- Press the control knob briefly: The control behaviour is changed.
- Press the control knob for longer than one second: The control behaviour is saved.
Adapting the valve type.
The LED flashes red for valve type “deenergized closed” (NC) and red/blue for valve type “deenergized opened” (NO).
- Press the control knob briefly: The valve type is changed.
- Press the control knob for longer than one second: The valve type is saved. The setting mode is exited automatically.
- After approx. 2 minutes without any operation the menu is exited without sav-ing.
Setting the temperature limits
The room temperature controller has a setting range of 5 … 30 °C. The adjustment rings on the central plate can be used to limit the temperature setting range.
- The specified temperature values may deviate from the actual room temperat-ure depending on the installation location.
- Pull the control knob (5) off the central plate (4) so that the adjustment rings (7) are visible (see figure 4). The temperature values shown in the picture are for orientation purposes.
- Turn the large blue adjustment ring clockwise to the desired minimum temper-ature. Each notch corresponds to a change of about 1 °C.
- Turn the small red adjustment ring anticlockwise to the desired maximum tem-perature.
- Replace the control knob, observing the coding of the control knob and rotary axle.
Setting the offset
This function allows the adjustment of the position of the control knob so
that it cor-responds to the room temperature. Thus, the indication of the
temperature via the control button is comparable in different rooms. An
adaptation of up to +/- 3 °C is possible.
- This setting is only possible if the lower temperature limit has not been raised by the blue setting ring (see Setting the temperature limits).
Precondition: The desired setpoint temperature has been reached in the room.
- Turn the control knob to 5 °C (left stop) and press twice in quick succession (double-click).
The LED flashes quickly, alternately red and green.
- Turn the control knob to the desired position for the current room temperature and press it for longer than one second.
The control knob position is saved and the LED lights up green for 5 seconds. If the LED flashes red for 5 seconds, the change was greater than +/- 3 °C and the adaptation is discarded.
