No fuel detection time
The time countdown starts after the flame brightness has dropped below
the value of the
Flame detection parameter. After the countdown is
finished, the controller attempts to ignite the burner and should it fail
three times, an alarm message of “ignition failure" is indicated.
Max. burner temperature
Defines the maximum feeder temperature. Should the value be
exceeded, the "maximum feeder temperature exceeded" alarm is
generated.
Max. flue gas temperature
Defines the maximum flue gas temperature. Should the value be
exceeded, the "maximum flue gas temperature exceeded" alarm is
generated.
Additional feeder operation time
Defines the additional feeder (bunker feeder) operation time. The feeder
is attached to the additional B module. After that time, the additional
feeder operation is stopped despite the fuel level sensor contacts are
open. The fuel level sensor contacts are located in the additional B
module.
Exhaust fan
Activates the operation of the exhaust fan.
Min. exhaust fan power
Minimum exhaust fan power in % selectable by the user. It is used only
to limit the available fan power range. It is not used for the fan control
algorithm and should be as low as possible to ensure slow and smooth
fan rotation and unrestricted flue gas extraction.
Vacuum sensor
Activates the operation mode with the vacuum sensor. Once the mode is
activated, the rotational speed of the exhaust fan is set by the controller
to reach the required value of the vacuum in the combustion chamber.
Min. vacuum
Defines the minimum value of the vacuum in the combustion chamber.
Should the value be exceeded, the "minimum vacuum exceeded" alarm
is generated.
Max. vacuum
Defines the maximum value of the vacuum in the combustion chamber.
Should the value be exceeded, the "maximum vacuum exceeded" alarm
is generated.
Vacuum correction
Corrects the vacuum sensor readings.
Vacuum - blowing correction
Defines the allowed exhaust fan blowing power variability range for
operation with the vacuum sensor.
Feeder calibration
Calibrates the efficiency of the feeder. Requires boiler shutdown.
14.2 BOILER
Thermostat selection
Options to choose from:

Deactivated (deactivates room thermostat influence on boiler
operation)

Universal (activates room thermostat for boiler)

ecoSTER T1 (option available after connecting room panel Room
Control, boiler operation is dependant on room thermostat No1 in
Room Control)

Room Control T2 (option available after connecting room panel
Room Control, boiler operation is dependant on room thermostan
No 2 in Room Control
– on sensor CT7)

Room Control T3 (option available after connecting room panel
Room Control, boiler operation is depended on room thermostat
No3 in Room Control
– on sensor CT7)
Min. boiler temp.
Minimum preset boiler temperature which can be set in user menu and
minimum temp. which can be set automatically by controller, i.e. from
night reductions etc.
Max. boiler temp.
Maximum preset boiler temperature which can be set in user menu and
minimum temp. which can be set automatically by controller, i.e. from
night reductions etc.
Reserve boiler
Description in point 12.13
Alarm indication
Configuration of the alarm output so that it is activated if one or more
selected alarms occur.
