Operation functions
After switching the burner on, it is appeared on the LCD screen the program's logo defining the
type of the driver and the version of the current software
While activating, the burner carries out a test of the connected sensors. In case of one lacking,
on the screen appears an appropriate message (---). The work of the burner without a heating
water temperature sensor (CH) is blocked and an emergency mode is activated (CH pump is
still on).
Correct connection of sensors causes displaying of actual CH furnace's temperature and the
temperature of useful warm water of the WUW buffer (if the function is active). On the screen
appears which function is currently used by the driver.
The burner may work in three working modes (“STOP”, “IGNITION”, “AUTOMATIC WORK”).
The mode changes when the “MODE/ ” button is pressed. Activating the “STOP” mode is
possible in all modes after pressing the “MODE/ ” button for 3 seconds. When Stop is
activated, the burner goes at “Burning off” process (if there is fire) and the at “Cleaning”
process.
When the burner is activated for first time, it is on “Stop” mode. Every next time, its status is
saved in the regulator's non-volatile memory. Activating the driver again, automatically causes
switching on of the lately used working mode.
In the table beneath a short description of particular functions of the burner, activated
depending on the working mode of the driver, is shown.
