Factory Settings
III.k)
The regulator has been pre-configured. However, it should be adjusted to your individual needs. It is
possible to return to the factory settings at any time. By enabling the Factory Settings, all existing boiler
settings will be replaced by settings made by the manufacturer. From then on, you can again set your
own operating parameters for the boiler.
Fitting parameters
III.l)
Access to fitting parameters is disabled for the user. This special view contains advanced
parameters accessible only by the manufacturer.
IV. Protections
In order to ensure a safe and faultless operation, the regulator has been provided with numerous
protections. In the case of an alarm, an acoustic warning is sounded and the display shows a
corresponding message.
Press MENU button to restore the controller to operation. In the case of the C.H. Temperature Too
High alarm, wait until the temperature drops below the alarm value.
Thermal protection
IV.a)
The boiler is protected with an additional bimetal sensor (located at the boiler temperature sensor) that
disables the fan when the temperature exceeds the critical value: 85
boiling in the system when the boiler has been overheated or the controller is damaged. When the
protective function is enabled and the temperature drops to a safe value, the sensor will automatically
restart the device and the alarm will be deactivated. If the sensor is damaged or overheated, the burner,
fan and feeder are disabled.
Automatic Sensor Check
IV.b)
When the temperature sensor of the central heating or hot consumption water is damaged, an
alarm is sounded with an additional indication shown in the display, e.g.: „C.H. Sensor Damaged".
Blow is disabled and both pumps are activated simultaneously, regardless of the temperature.
If the central heating sensor is damaged, the alarm will remain active until the sensor is replaced. If the
hot consumption water sensor is damaged, pressMENU to deactivate the alarm and restore the single
(house heating) pump mode. To be able to operate the boiler in all modes, it is necessary to replace the
sensor.
Temperature Protection
IV.c)
The regulator features an additional protection in case the bimetal sensor is damaged. After the
temperature exceeds 85 O C, the alarm is sounded with the display showing the following message:
O C. This is to prevent water from
