Antifreeze protection (warning)
Cause:
Control light 2 yellow:
Correction:
Reset:
Boiler temperature is < 7°C, when the boiler
is switched off
Lights
Do heat-up and burn-out
Automatically with new burn-out (button +),
or when the boiler temperature is > 8°C
Emergency program: Yes, burn-out is possible - do that!
Antifreeze protection
Boiler temperature
(°C)
Actions of regulator: At boiler temperature < 7°C:
Circuiting pump starts
By this action, if there is warmth of the tank,
it is taken off. If there is no warmth in the
tank, the freezing point in circuiting water
decreases.
At boiler temperature > 8°C:
Circuiting pump is switched off
Incorrectly measured values of Oxygene sensor – Lambda probe (error)
Cause:
Control light 2 yellow
Non-apparent heating by means of sensor
error in electric circuit or short circuit
Lights
Correction: Check sockets and conductors.
Demount and clean oxygene sensor. If it is
necessary, replace it.
Reset:
Emergency program:
Actions of regulator:
Automatically after error removing and
resetting of scale of the oxygene sensor.
Regulator works with alternative air V1 and
V2. After burning-out, the boiler must be
manually switched off by the „-“ button.

Not to shorten the boiler´s life-time, it is necessary to remove the
error immediately! Possible expiration of warranty!
Errors, functions and actions of regulator - summary
Errors and functions Actions or operation of the regulator
Power failure When the power is supplied again, the operation state is
regenerated, same as it was before.(boiler starts or stops again)
Too high boiler temperature < 90°C: fan is stopped
> 89°C: fan is switched on
Incorrectly measured values
of boiler temperature
Stop of flue gas fan and connection pump. It is not possible to
turn the boiler on.
Incorrectly measured values
of flue gas
It is possible to turn the boiler on. Regulator works with
alternative air V1 and V2. After burning-out, the boiler must
be switched manually!
Incorrectly measured values
of O2 sensor (Lambda probe)
While heating-up, no line graph is dislayed.It is possible to
turn the boiler on, regulator works with spare air V1 and V2.
Automatic function of switch If the boiler is switched on for 30 minutes and flue gas
