Function
1. Operating switch ON-Thermostat ON-Gas pressure switch ON-Air damper closed.
A control is made that the air pressure switch does not indicate fan pressure. Then the
burner motor starts.
2. Air damper motor opens.
The air damper motor opens the damper to full load. A control is made that the air pres-
3. Air damper motor closes.
The air damper motor closes to low load . Then the ignition spark is formed.
4. Main and safety valves open
5. The safety time expires.
6. Operating position.
The burner is in operating position and can now change over to full load if the operat-
ing switch and the thermostat for full load are in positon ON. The burner can alternate
between full and low load depending on set temperature.
7. Stop.
The operation of the burner can now be interrupted by means of the operating switch or
the thermostat.
• The control locks out.
The red lamp in the control is lit. Restart the burner by pressing the reset button.
