6.3. Operating instructions diraTRON load controller
The burner load is typically controlled by the climate computer (through Fiduface).
The burner selector switch is set to
“external”.
When the burner load is not controlled by the climate computer, it is controlled by a
the diraTRON 108H load controller. This is the case when the
burner selector
switch is set to “automatic”
or
when there’s an error in the climate computer’s
system (then the diraTRON automatically takes over).
The diraTRON 108H is a modulating burner load
controller. It initiates the burner start/stop and controls
its load based on the requested boiler temperature
(setpoint).
The
corresponding display, integrated in the burner’s
switch panel casing shows the following values:
(1)
The requested boiler water
temperature in °C (setpoint).
(2)
The actual boiler water temperature in
°C (actual value).
Press the up and down arrow keys
(
)
to
change the setpoint. Using the keys automatically
brings you to the change setpoint section in the
menu. Use the menu/OK key (3) to set the
setpoint
.
Note: the burner starts when the boiler
temperature is 2°C under the requested
value and stops 6°C above the requested
value.
In the case that the burner load is controlled
externally by the climate computer, the diraTRON
still shows the actual value for burner load.
