numerous protections. In the case of an alarm, an acoustic warning is sounded and the
display shows a corresponding message.
Press the encoder 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.
.13. Thermal protection
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
O
C. This is to prevent water from 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.
.14. Automatic Sensor Check
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.
.15. Temperature Protection
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:
The current temperature is read from an electronic sensor and processed by the
thermoregulator. When the alarm temperature is exceeded, the fan is shut off and both
pumps begin to run in order to distribute hot consumption water throughout the system.
.16. Anti-Boil Protection
This protective function is used only with the water heater priority mode. For
example, when the water heater setpoint temperature is 55
O
C and the boiler
temperature rises to 67
O
C (5
O
C over the so-called priority temperature), the controller
