Error Messages

I Information:Possible errors or malfunctions which can arise during operation are displayed by the electronics in the display with an error number EXX.X and   with a short description of the error as well.¾ These errors can subsequently be read from the error memory r38 in the service programme.   Using the “Mr.C” button the date and time of the error message can be called up. ¾ In error mode all actuators are switched off, the buzzer   sounds and the appliance goes into error mode. After confirmation of the error with the button, the CONVOTHERM can only be operated with   the emergency programmes.Possible error messages.

 Water Quality Testing

Has the maximum allowed water hardness been exceeded? In OEB and OGB a water hardness of over 18°, this is with heavier scale   build up in the steam generator, a water softening system is recommended: an hydrogen ionic exchanger! In OES and OGS, a water   hardness of over 7° a water softening system (recommended is: an hydrogen ionic exchanger such as an partial decalization system   from the company Brita) is absolutely necessary Information can be acquired from your water supplier. no  yes  if , yes, which   measures were taken?

Attention – Working in the connection area of the unit: Work in the connection area of the unit must be carried out by a qualified electrician in accordance with the local power supply company regulations as well as current EU regulations. When working in the connection area, the unit main power supply must be shut off (an all-pole isolation switch with a minimum contact opening of 3mm must be located close to the unit) Make sure that the unit’s power has indeed been switched off! After servicing, a final test, according to the local and current regulations, must be performed.

Attention – working on the unit’s gas system: Working on the gas technology in a unit can only be performed by a qualified installer from an authorized gas supplier. Check all connection points outside and inside the unit for sealed tightness (with a gas detector or leakage spray). Attention: Do not spray leakage spray on electrical components of the ignition and flame monitoring devices!
