TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL
overheated, the burner, fan and feeder are disabled.
Аutomatic 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 then 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, pres MENU
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.
Тemperature Protection.
The regulator features
an additional protection in case the bimetal sensor
is damaged. After the temperature exceeds
85°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.
Anti-Boil Protection.
This protective function is used
only with the water heater priority mode. For example,
when the water heater setpoint temperature is
Modèle and the boiler temperature rises to
67°C
(
5°C
over the so-called priority temperature), the
controller shuts off the fan. If the boiler temperature
reaches
80°C
, the C.H. pump will be activated. If the
temperature continues to rise, the alarm will be
activated at
85°C
. Such condition may appear when
the water heater or the pump is damaged or when
the sensor has been improperly installed. However,
if the temperature drops, the controller will activate
the fan at
66°C
and it will remain in the duty mode
maintaining the priority temperature of
62°C
.
Monitoring the flue gas outlet temperature. This
sensor constantly monitors the flue gas outlet
temperature. If the sensor is damaged, disconnected
from the controller or removed from the flue conduit,
Flue Gas Sensor Damaged massage will appear on
the display. This will cause the controller to switch
to the emergency mode. In such case, only boiler
temperature is used. The controller is operated using
only the boiler sensor and the zPID function remains
active without the flue gas outlet sensor.
Fuse.
The controller has a network protection WT
3.15 A
tube fuse. Higher current ratings may cause
damage to the controller.
