Working Princlipe Of Control Panel
Adjusting External Air Thermostat
Environment Compensation:
Device; allows to adjust activation temperature difference for both burner stages and activation
temperature value for pump. When Open/Close button is pressed, burner is activated at the
second level. In the meantime, it will display “burner activated” indicator. Boiler water starts to
warm up. When boiler water reaches the temperature of pump activation temperature, pump is
activated, when the pump is activated, related indicator is activated (Pump Active).
While boiler water temperature increases, when it reaches temperature difference value adjusted
for the first stage of the burner, burner falls to the first stage. When boiler water temperature
reaches thermostat value adjusted by user, burner switches to off position.
After boiler water reaches thermostat value and burner switches to off position, boiler water
begins to cool. During cooling down, when there is temperature difference between boiler water
temperature and adjusted thermostat temperature as much as “burner first stage difference
temperature”, the burner is activated at first level. If the temperature continues to fall, when there
is a difference between boiler water temperature and adjusted thermostat value as much as
“burner second stage difference value”, the burner is activated at the second stage.
System is closed by pressing open/close button on the panel.
Safety relay prevents the system reaching a temperature over 95 degrees regardless of the
processor. In this case, the device shuts down the burner. In order for burner to be reactivated,
boiler water should be cooled down to 62 (+-5%) degree.
By press Select button until (external) appears
and entering (external) menu, environment
compensation is activated with AUTO and
deactivated with OFF by adjusting with up and
down arrow keys, and wait 12 sec. and saved
in memory.
If this setting is selected as AUTO, control
Temperature equals to adjusted environment
Temperature difference. If selected as OFF,
control Temperature equals to adjusted
thermostat temperature.
