New technical requirements have been realised with this update.
This includes the required adjustment of Angular JS to Version 1.8.
Furthermore, optimisations have been made, which enhance your user experience.
We look forward to your feedback on the new version.
Some of our units have an error code that gives us more detailed information about the cause of the error.
The flashing code is similar to a Morse code. This means short and long flashing characters in an individual sequence (e.g. short, long, ls slls).
This can be used to offer faster help when contacting your dealer, service partner or our service centre.
Mover
On the Mover models, the flashing code consists of eight consecutive characters. This is repeated several times, each time starting anew after a pause of approx. three seconds.
As soon as a fault is indicated on the remote control, the LED (j) on the control unit emits the flashing code.
These mover models have the flashing code output:
l
Combi 4/6 (E)
With the Combi Gas connected to the CP classic analogue control unit, the flashing code also provides more precise information on the cause of the fault.
If the control unit reports a malfunction, the cause can be narrowed down more precisely using the flashing code on the heating board.
For Combis manufactured before 06/2018, there are eight flashes of the red LED. For Combis produced later, the number was increased to ten characters.
You are welcome to send us flashing codes by e-mail as a video or directly name them by telephone.
The LevelControl measures the cylinder level via ultrasound. For this, it is necessary that the coupling pad of the device has clean contact with the bottom of the gas cylinder.
Suitable are upright (propane / butane – LPG) steel or aluminium gas cylinders with a diameter of 200 to 350 mm.
Depending on the cylinder type and age, there may be different obstacles to clean measurement.
Here are some examples of obstacles and the corresponding solutions:
Bottle heavily rusted/dirty
Due to the uneven surfaces caused by rust, the ultrasonic signal can no longer penetrate cleanly into the bottle. A measurement is therefore not possible.
In this case, it is recommended to mount the LevelControl in such a way that the coupling pad rests on a surface that is as smooth as possible. In severe cases, the only solution is to replace the bottle.
Bottle stand base too narrow
On such a bottle, the LevelControl has no place underneath. The bottle rests with its entire weight on the LevelControl and squeezes the coupling cushion. This also means that no measurement is possible.
The supplied feet or other distance blocks can provide a remedy.
Bottle base dented/flattened on the underside
If the LevelControl is attached to the centre of such bottles, the coupling pad no longer rests on the ground as desired. A measurement is therefore not possible at this point.
In this case, simply move the LevelControl a little out of the centre.
Tank bottles/gas tanks
Tank bottles have a special interior that enables refuelling (fuel indicator, etc.). This interior deflects the ultrasonic signal of the LevelControl so that no measurement result can be calculated and displayed.
The LevelControl cannot be used on such bottles/tanks.
Thanks to the customers who sent us the photos for better clarification.
You see the warning message “W255H” on your digital display and cannot control your heating anymore?
This primarily indicates a connection problem between the digital control panel and the heating. In this state, commands entered cannot be transmitted or cannot be transmitted correctly.
Attention!
A reset on the CP plus is not used to delete an error, but corresponds to an initialisation, i.e. a device search.
If the reset is carried out while there is a connection problem to the heating, the heating menu is completely lost. Only the time and the setup symbol remain.
Two factors can be considered as causes of the connection problem:
Communication is only possible if the heater is powered in addition to the control unit. If this is not the case, the control panel responds with the message W255H.
Please check the heating fuse in your electrical block as well as the fuse on the control board of the heating (Combi) or in the supply line (Varioheat). Replace a defective fuse if necessary.
Note: In our installation instructions, we recommend installing our units on permanent plus.
This means that the power supply to our units cannot be switched off by the central control element (main panel). There should be a permanent connection via the electrical block to the body battery.
The TIN cable is used to transmit commands from the control panel to the heater. If this connection is interrupted, the control panel responds with the message W255H.
Please check whether the plug of the TIN cable is correctly seated in the socket on both the control element and the control board of the heater.
As soon as the cause is eliminated, the warning message disappears automatically from the display.
Advice for Combi D: If the installed TIN cables exceed a total length of 12 metres, an error may occur in the communication with the digital control unit (W255H). The “control panel cable coupling” accessory provides a remedy.
Please place this coupling between the TIN socket on the heater and the TIN cable. If two TIN sockets are occupied, it does not matter which of the two TIN cables the coupling is used with.
The article “control panel cable coupling” can be ordered from our specialist dealer (part number 39050-00175).
