2.4 Burner operation
2.4.1 Control operation
The microprocessor-based burner controller is made for fan assisted, direct burner ignition
applications.
The control powers the gas valve and DC-fan. Normal heat demand is given by a 230 VAC switch
input (depending on the model)
After heat demand and successful ignition, modulation can be controlled by external 0 - 10V or
4 - 20mA signal.
2.4.2 Basic sequence of operation
The Normal Heating mode is started when the High Voltage Heat Demand input is closed. When
ignition is successful, the fan can be controlled in a number of ways depending on parameter
setting:
•
0-10 V control , a DC voltage between zero and ten volts can be applied to connector (X3
Pins 8 & 16). At zero volt the fan will run on Minimum Fan speed. At ten volt the fan will run
on Maximum Fan speed.
•
4-20 mA control , with an external resistor of 500
Ώ 1 % placed between connector (X3
Pins 8 & 16), the fan speed can be controlled with a current in the range of 4 to 20 mA.
At 4 mA the fan will run on Minimum Fan speed. At 20 mA the fan will run at Maximum Fan
Speed.
•
On/Off control , when the option On/Off control is selected, the fan speed depends on the
fan Slope control parameter: When slope control is off (parameter set to zero), the fan
speed will immediately go to maximum. Otherwise the fan speed will rise from Ignition Fan
speed to Maximum Fan speed with(value)*50 RPM/sec. Slope control works for both
increasing and decreasing of fan speed.
