SHUT DOWN)
Fuel ignition in auger channel. The controller empties ignited fuel from the auger channel until temperature drops.
ALARMS Safety and temperatures sensors failure alarms.
STOP.
Controller maintains central heating and domestic water pumps operation only to protect the boiler against overheating and auger channel ignition. Room thermostat contacts closing(call for heat) and domestic water temperature drop do not result in any action. Pressing START button will result in switching the controller to STAND-BY mode.
STAND-BY.
In this mode controller does not carry out any additional operation, until room thermostat contacts close (call for heat) or domestic water temperature drop, the boiler operation will focus on maintenance of temperature according to thermostat setting programmed with the knob. If preheating of domestic water tank is necessary and the desired boiler temperature setting is higher from domestic water temperature setting the controller will follow higher setting. Pressing the STOP button () will result in switching to STOP mode.
IGNITION.
Boiler controller is switched into IGNITION mode if demand for heat follows, and if the controller did not detect the flame. During ignition the controller activates fan, auger and igniter. Fuel and air feeding rate is adjusted by the technician. IGNITION

mode follows till flame is detected. If the flame is not detected within the specified time, the controller activates „Out of fuel alarm”. Pressing STOP button, exceeding time limit for cleaning, thermostat contacts opening or if water temperature in domestic water tank is obtained during operation in IGNITION mode will result in switching of the controller into EXTINCTION (SHUT DOWN) mode.
Stabilization of the firing.
Boiler burner is switched to the stabilization of the detected flame ignition. While stabilizing the fan runs at a speed the same as when operating in maximum power. Tray gives fuel quantity such as the minimum power. In addition, depending on the service settings fuel dose may be increased gradually. Stabilization of the firing continues for the time programmed in the settings of the service or until the boiler temperature. Pressing the STOP button, exceeding the working time without cleaning, opening the contacts of the thermostat or to achieve the required water temperature in the hot water tank during operation stabilization ignition, the controller will switch to after-burning mode.
CAUTION! Stabilization of ignition can be turned off by a service technician. In this case, after the fire the controller switches to work with maximum power.
MAX. POWER OPERATION MODE.
MODULATED POWER OPERATION MODE.
MINIMUM POWER OPERATION MODE.
When in this mode the controller operates fuel feeding and fan operation to maintain firing to ensure the minimum fuel consumption. Fuel and air feeding rate is adjusted by the technician. If in spite of boiler minimum power, increase temperature follows of water temperature in relation to the top hysteresis parameter setting, the controller will be switched into EXTINCTION(SHUT DOWN) mode. When the boiler water temperature drops below the desired setting it will result in switching of the controller into „max power operation mode”. Pressing STOP button, exceeding time limit for cleaning, thermostat contacts opening or if water temperature in domestic water tank is obtained during operation in MINIMUM POWER mode will result in switching of the controller into EXTINCTION (SHUT DOWN) mode.
