the boiler burn out, in case when the
temperature will hold over the set point
value.
ATTENTION: Improper setting
of this option may cause a
constant rise of the temperature!
Suspension pause shouldn’t be
too short.
12.13. Language
This function allows the user to change
the language version.
12.14. Factory Settings
There is always the possibility of returning
it to factory (default) settings. Switching
on this function will cause the user to
lose all personal device settings which
will be replaced by the settings saved by
the manufacturer (this does not apply to
settings of the service menu). At this point
it is possible to re-set personal settings of
the controller.
12.15. Controller safeguards
In order to ensure a safe and faultless
operation, the controller 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 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
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°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 fan is disabled.
Automatic sensor check
In case when the CH temperature sensor is
missing or damaged an alarm is activated,
which additional reports the fault on the
display e.g.:
The fan is being turned off, whereas CH and
HCW pumps are operating independently
from the current temperature, each in
accordance with its specific settings. In
case of CH sensor damage, the alarm will
remain active until the sensor is replaced.
If the HCW sensor is damaged, the user
should press MENU which will turn off the
alarm and the controller will return to one
pump operation (house heating). In order
for the boiler to operate in all modes the
sensor needs to be replaced.
Temperature protection
After the temperature exceeds 85°C, the
alarm is sounded with the display showing
the following message:
