Operation parameters of flue gas fan
Fan output [Π100] - this value defines fan output. When the "Πr" is on "0-10", it is max. fan
output that can be reached during automatic fan operation.
Minimum fan output [n 40] - the lowest fan output, that can be used, when are the fan
rotations controlled automatically and when the fan rotations continually increase during
boiler start-up.
Coefficient of the fan speed decreasing [Πh10] - this parameter influences way of the fan
speed decreasing, when the boiler temperature is near to required value. For example, setting of
this parameter to the value of 2 means, that when is regulator in the operation mode and boiler
temperature is for 2°C lower than the required boiler temperature, fan will work at max. output
[Π100]. Next increasing of boiler temperature causes continual decrease of the fan output up to
its minimum [n 40].
Automatic regulation of the fan rotations [Πr 1] - is active, when this parameter is set to „0-
10" and causes automatic decrease of fan rotations, when temperature of water in the boiler
reaches required temperature. If is the parameter set to „-", then is the automatic decrease of fan
rotations inactive and fan works at output set by the "Π" parameter. Setting of the parameter
value in the range from 0 to 10 means time in minutes of the continual increase of the fan speed
from 40% up to the value "Π" for correct boiler start.
Operation time of ventilator [Πn 5] - time of ventilator rotation that is necessary for suction
of accumulated gas before and after loading. By setting the parameter to „-" is the function
inactive. This function can be activated in the OPERATION mode.
Ventilator pause [Πu 6] - time between operation periods of the fan.
Operation time of the fan in the manual mode [Πd 3] - this parameter determines, how long
will the fan work, when it was activated manually. By setting of this parameter to „--" is the
option of manual fan operation inactive.
Parameters of the central heating pump.
Temperature of the C.H. pump start [P 65] - temperature of water in boiler that causes start
of the C.H. pump. Circuiting pump works independently on boiler control process, but it is
started by boiler control in case of boiler overheating.
Hysteresis of the C.H. pump [Ph 5] - this parameter defines at which value of decrease of the
boiler temperature under the temperature of the pump start will be the pump stopped.
Operation mode of the C.H. pump [Pr 1] – the C.H. pump, independently on the operation
mode, is always inactive, when the boiler temperature decreases under value set by the [P 65]
parameter and it is always started, when the boiler temperature exceeds 90°C, when the boiler
is overheated or when the temperature sensor is damaged. In remaining cases, the C.H. pump
works in the mode set by parameter [Pr]
 mode [Pr 0] - permanent operation
 mode [Pr 1] - pump work depends on additional thermostat work mode. In [Fc 0] mode
central heating pump is turned on when room temperature is too low (additional
thermostat connection shorted or room temperature lower than temperature set with
additional thermostat knob). The pump is turned off when room temperature reaches
desired value. In [Fc 1] mode central heating pump is turned on when measured exhaust
gas temperature is higher than temperature set with additional thermostat knob. The
pump is turned off when exhaust gas temperature drops below the set temperature.
 mode [Pr 2] – in this mode is the C.H. pump started only when the regulator is in the
operation mode
