Combustion air
Fan (300 - 700) ver. 3
Combustion air provides the needed air pressure
and volume for efficient combustion.
In the WD200 system, the fan motor can be fitted
with a variable speed drive. The variable speed drive
adjusts air pressure according to burner’s capacity
by controlling the fan speed.
Operating and display unit
AZL ver. 4
The WiseDrive system operating and display unit is
used for monitoring and adjusting settings.
The menu is available in several languages.
The operating and display unit has an internal
memory backed up by a battery. The memory stores
the burner control parameters. Battery durability is
approximately 10 years.
O2 module (WD200)
PLL52 ver. 3
O2 module and oxygen sensor measure the residual
oxygen content of the flue gases. Burner control
uses the measurements to monitor and optimize
the combustion process. Flue gas and combustion
air temperature sensors can be connected to the
system to measure efficiency.
