If the device fails to enter into installation status after the date setting is completed, the screen will have a scrolling display of “InS” and “n”, you can take off the battery and restart the process when the device enters into installation status successfully, the screen will display “Ada”, you can enter the next step to fix with Valve.
Adaptation
Note: The device is easy to install and can be done without draining heating water or intervening in the heating system. No special tools are required, nor does the heating system have to be switched off. The standard thread M30x1.5 ring adaptor(figure) can be directly used for the most popular manufacturers brand valves in the market. For some special Danfoss brand Value RA/RAV/RAVL, please use Danfoss valve adapters furnished in the accessories package (assembling as a figure on the next page). After the screen displays “AdA”, the heating radiator head is ready to be installed with the valve as follows.
- After the “AdA” display on the screen, the radiator head is ready to be fixed with the Valve, and the radiator head wheel axle will be at its start bottom position to be fixed well with the valve.
- Remove the old mechanical thermostat head from the valve.
- Fix the device to the valve, tightening the thread ring with the valve by hand.
- After installing the radiator head, press the Confirm key to start valve adaptation mode.
- After the “AdA” display on the screen, the radiator head is ready to be fixed with the Valve, and the radiator head wheel axle will be at its start bottom position to be fixed well with the valve.
- Remove the old mechanical thermostat head from the valve.
- Fix the device to the valve, tightening the thread ring with the valve by hand.
- After installing the radiator head, press the Confirm key to start valve adaptation mode.
Adaptive operation
The LED display in Figure “H” has a scrolling display for “AdA” and “_”. The device will do the auto adaptation process; if any problem, the screen will display “F1”, “F2”, “F3” and “F4” errors; if auto adaptation is correct, the device will enter into normal display mode. Notes:
- F1 — If the valve is driven slowly, check whether the valve is jammed;
- F2 — If the adaptation range is too wide, check whether the valve is not installed in place and whether the screw is tightened. and also try to add the plastic cap in the accessories package and repeat the adaptation process from the beginning.
- F3 — If the adjustment range is too small, check whether the heating valve is blocked and valve resistance is too large.
- F4 — The valve is not installed or valve travel was not detected properly. Repeat adaptation several times if necessary.
Due to material fatigue, the closing force and valve trace may be changed negatively. If the device shows error F4, uninstall the device and add one or two of the shims delivered in the accessories package as following figures between the valve and radiator adaptor. Repeat the installation adaptation process from the beginning.
Operating modes
The device has 3 operation modes: auto mode(automatic mode), Manu mode(manual mode), and holiday mode, and the device can be recurrently switched into different modes through a simple press on the touch mode key “G” (as figure). The LED “B” and “D” indicate three statuses:
- “B” lighting on holiday mode

switches to the next cycle times temperature automatically) Short press
recurrently on the touch mode key ”G”, until both key “B” and “D” lighting
off, the device enters auto mode. Rotate the knob right and left to adjust the
temperature value: the range is (0.5C-29.5C), with 0.5C for each rotation
step. The device will be operated based on the manual setting temperature
until the next automatic temperature skipping time is reached.
Manu mode Under the manual mode, The device will set the room temperature as the display temperature till it is changed to another mode, the temperature can be changed manually by the knob key.

“Tof ”- Temperature offset correction
As the device is installed with a heating radiator, its detected temperature
is near the radiator, it can be a discrepancy between real room temperature
and the measured temperature by the device. We can use this setting to correct
the temperature offset. Discrepancy setting can be between ±5°C. for example
actual room temperature is 18°C but the device indicate 20°C, we can set
+2.0°C. Inverse also. Rotate the knob to select the temperature offset(-5.5°C

saving mode under the Auto mode, the device will enter Auto mode automatically
again after the device finishes its present cycle time. Note : Comfortable
mode and energy-saving mode can only be used in manual mode and automatic
mode.
Stop mode
After the winter season, if users do not use the heating system any more. The
device can be set completely into heating-stopping mode. In this mode,
depending on the need for repair, the heating valve will be fully open/closed.
Anti-calcification protection remains effective in these two states. In the
manual mode, turn the knob to the right until the screen displays “On” to open
completely (in a condition that the heating system had been switched off by
the main Valve). Or turn the knob to the left until the screen displays “off”
to close completely. Turn the knob to the left to change the temperature on
the screen, device exits the stop mode.
Anti-freezing mode
If it is not necessary to provide heating for the room, the thermostat can be
set to anti-freezing mode. In this mode, the heating valve is closed, unless
there is risk of frost (when the room temperature drops to 0°C, thermostat
will open the valve automatically, until the temperature rises to 5°C). Anti-
calcification protection remains effective. Turn the knob to the left until
the screen displays “Off”, indicating that the device enters into anti-
freezing mode. Turn the knob to the right to change the temperature to exit
anti-freezing mode.
Child lock mode
Press the “Manu mode/auto mode/Holiday mode switching Key” “G” and “energy-
saving and comfortable mode Key” “E” simultaneously to open the child safety
lock and the screen displays “LOC” letter. Press the “Manu mode/auto
